Fuel system Toyota Corolla 120 body. Fuel filter Toyota Corolla - double replacement

High-quality fuel cleaning and uninterrupted engine operation under any operating conditions depend on the cleanliness of the filter. Therefore, Toyota Corolla is one of the most important operations in car maintenance. The design of the machine allows you to make a change with your own hands.

Where is the fuel filter located?

The fuel filter on modern Toyota Corolla cars is located in the fuel module inside the tank. This arrangement of the filter is standard for cars equipped with an engine with distributed fuel injection. On earlier models (produced before 2000), the filter is located in the engine compartment and is attached to the engine shield.

Replacement frequency

The manufacturer does not stipulate filter replacement as routine maintenance, and this equally applies to Toyota Corolla in 120 and 150 series bodies. Many services, based on the realities of car operation in Russia, recommend a preventive replacement every 70-80 thousand kilometers. Replacement can be made earlier, subject to the appearance of signs of contamination of the filter element. Since 2012, in the Russian-language service literature for Toyota Corolla, the filter replacement interval has been indicated every 80 thousand km.

Choosing a filter

In the fuel intake module at the inlet there is a coarse mesh filter, inside the module itself there is a fine fuel filter. For replacement, you can use original parts and their analogues. Before buying a filter, it is advisable to clarify the model installed on the machine.

When choosing original fine cleaning parts, it should be borne in mind that the Corolla in the 120th body was equipped with two types of filters. On the first releases from 2002 to June 2004, a part with catalog number 77024–12010 was used. On machines from June 2004 until the end of production in 2007, a filter with a modified design was used (art. no. 77024-02040). On the 150th body, a single filter option was installed (number 77024-12030 or a larger assembly option 77024-12050).

In addition, Corolla 120 cars were produced for the Japanese domestic market under the designation Toyota Fielder. These machines use a fine filter with the original number 23217-23010.

Analogues

The coarse fuel filter is usually not changed, but in case of damage it can be replaced with a non-original Masuma MPU-020 part.

Many owners, due to the high cost of original filters, begin to look for more affordable parts with a similar design. However, for cars in the 120th body, such parts simply do not exist.

For the 150th body, there are a number of cheaper analogues, from the manufacturers JS Asakashi (FS21001 number) or Masuma (part number MFF-T138). For those who want to save money, there is a very cheap version of the Shinko filter (SHN633).

For Fielder, there are similar Asakashi (JN6300) or Masuma (MFF-T103) filters.

Replacement for Corolla 120 body

Before starting work, it is necessary to empty the tank as much as possible, preferably before the reserve fuel remaining lamp turns on. This is necessary to minimize the risk of spilling gasoline on the upholstery.

Tools

Before replacing the filter, prepare the following materials and tools:

• screwdriver with a thin flat sting;
• Phillips screwdriver;
• pliers for dismantling the spring clip;
• rags for wiping;
• a flat container over which the pump is disassembled.

Step-by-step instruction

Action algorithm:

1. Raise the left rear seat cushion and fold back the noise insulation mat to gain access to the hatch of the fuel intake module.
2. Clean the installation site of the hatch and the hatch itself from dirt.
3. Unfasten the hatch installed on a special thick mastic with a screwdriver. The mastic is reusable, it should not be removed from the mating surfaces of the hatch and the body.
4. Wipe off accumulated dirt from the fuel module cover.
5. Disconnect the power connector from the fuel pump block.
6. Start the engine to run out the pressurized fuel in the line. If you neglect this item, then gasoline will flood the car interior when the tube is removed.
7. Disconnect two pipes from the module: fuel supply to the engine and fuel return from the adsorber. The pressure tube is clamped to the module by a retainer that slides sideways. The second tube is fixed with a conventional ring spring clip.
8. Unscrew the eight screws with a Phillips screwdriver and carefully remove the module from the tank cavity. When removing the module, it is important not to damage the side-mounted fuel level sensor and the float mounted on a long lever. It is better to carry out further work on the prepared container in order to prevent the ingress of gasoline residues from the module onto the elements of the car interior.
9. Disconnect the lever latch and remove the float.
10. Separate the halves of the module housing. The plastic connector clips are located closer to the top of the module. The clips are quite fragile and it is important to carry out this operation carefully.
11. Remove the fuel pump from the module and disconnect the filter from it. The fuel pump will come out with effort due to the presence of rubber o-rings. It is important not to lose or damage the rings that keep the fuel pressure in place.
12. Now you can change the fine filter. We blow the module housing and the coarse filter with compressed air.
13. Assemble and install the module in reverse order.

Replacing the filter on a Corolla 120 hatchback

On a 2006 hatchback car, the fuel filter is installed differently, so the replacement procedure has a number of nuances. Also, such a scheme was used on all 120s of the British assembly Corollas.

Replacement sequence:

1. The module hatch is mounted on four bolts for a Phillips screwdriver.
2. The module itself is tightly inserted into the tank body; a special puller is used to remove it.
3. The module has a completely different appearance. To disassemble it, you must first disconnect the hose at the base of the module. The hose can only be removed after preheating with a hair dryer.
4. The filter itself with the pump is located inside the module glass and is attached to three latches.
5. The fuel gauge must be removed to access the filter.
6. The filter can be removed from the cover of the module only when heated by a hair dryer. The fuel lines will have to be cut. It is important to remember which of the filter tubes is the inlet and which is the outlet, since there is no marking on the body.
7. Press the pump out of the filter with a 17 mm bolt.
8. Install a new Toyota 23300-0D020 filter (or an equivalent Masuma MFF-T116) and mount new pipes between the filter and the pump. The tubes must be easily bent, since the pump halves are in a preloaded state in the tank.
9. The coarse filter is in a glass and is simply washed with carburetor cleaner.
10. We carry out further assembly and installation in the reverse order.

An important point in the work is to ensure the tightness of the landing of new tubes on the fitting. It is better to check the quality of work before installing the module in the tank using a pump and a soapy solution. According to a number of reviews, the MFF-T116 filter does not fit tightly on the pump. Below is a series of photos explaining the replacement procedure.

Replacement of TF in the 150th body

Replacing the fuel filter with a 2008 Toyota Corolla (or any other) in the 150th body has some differences from a similar procedure on the 120th body. When replacing, ensure that the O-rings are correctly positioned as they hold pressure in the fuel system. Since 2010, a safety system has been used, the essence of which is to operate the fuel pump only when the engine crankshaft rotates. In the absence of residual pressure in the system, the starter has to turn the engine much longer until the pump builds up pressure in the gasoline supply pipe.

Preparation

Since the design of the modules is similar, there are no special requirements for the tools and equipment of the workplace. You will need the same tools and materials as when replacing the filter on machines with a 120 body.

Stages of work

When replacing the filter on the 150th body, there are a number of points that you should pay attention to:

1. The fuel module is fixed on the tank with a plastic threaded ring equipped with a rubber seal. The ring turns counterclockwise. To remove the ring, you can use a wooden rod, which is attached to the edges of the ring at one end, and lightly hit with a hammer on the second. The second option may be to use the gas wrench handles, which clamp the ring by the ribs.
2. The module has additional fuel pipes for ventilation of the tank cavity. Disconnecting the tubes is the same.
3. There are two seals in the module design. The rubber sealing ring 90301-08020 is placed on the fuel pump at the place where it is installed in the filter housing. The second ring 90301-04013 is smaller and fits into the check valve fitting at the bottom of the filter.
4. When reinstalling, carefully install the nut gasket. Before re-tightening the nut, it is necessary to install it until the marks on the nut itself and on the body (near the fuel hose to the engine) are aligned, and only then tighten it.

The main points of the process are explained in the photographs.

Filter on other Corollas

On the Corolla with a body 100, the filter is located in the engine compartment. To replace it, you must remove the rubber air supply pipe from the filter to the throttle module. The branch pipe is fixed with conventional screw clamps with a 10 mm nut. A fuel pipe, fixed with a 17 mm nut, fits the filter, the filter itself is fixed to the body with two 10 mm bolts. The lower fuel supply hose can be unscrewed through the hole for steering rods in the left arch. There is no pressure in the system, so the flow of gasoline will be negligible. After that, you can install a new filter (often the cheapest SCT ST 780 is used). A similar filtering system is used on the Corolla model 110.

Another option is the right-hand drive model 121 Corolla Fielder, which can be front-wheel drive or all-wheel drive. The location of the module on it is similar to model 120, but only on machines with all-wheel drive. On such configurations, an additional fuel sensor is installed on the right. In this case, the module itself has only one tube. On machines with front-wheel drive, the module is installed in the center of the body and two pipes go to it.

When removing the module from the tank, it is necessary to remove the additional fuel intake pipe from the second section of the tank. This tube is only on all-wheel drive Fielders. On a front-wheel drive car, there is a conventional pressure regulator valve.

Increasingly, designer cars are abandoning quick-change fine fuel filters: by placing a large-area cartridge directly in the fuel module housing, they lay in it a service life equal to the theoretical resource of the fuel pump. The only replaceable fuel cleaning element on such cars is the mesh at the fuel pump inlet. retaining the main part of mechanical impurities. However, taking into account the quality of the fuel, it is on it that the main load falls.

By replacing the fuel filter on your own with a Toyota Corolla, the owner can protect himself from many "surprises" in the future: as a rule, jerks during acceleration are the result of a filter that is suitable for a critical level of contamination.

Other problems that amateur writers like to scare so much have nothing to do with this: neither start-up deterioration, nor engine tripping at idle do not occur, since fuel consumption in such modes is minimal, and even with a clogged filter, the fuel pump manages to supply sufficient volume gasoline into the highway - if the filter is so clogged that it is noticeable even at idle, then such a car could not drive on its own for a long time.

How often do you need to replace?

Replacing the Toyota Corolla fuel filter in 120 (2000-2007) and 150 (2008-2012) bodies is not provided by the manufacturer as a routine operation. This work is done only at the beginning of the diagnostic procedures, if a pressure drop is detected with increasing engine load (that is, at times when the engine fuel consumption is highest).

Considering that the fuel filter is built into the fuel module housing and is not cheap even in non-original form, few people decide to perform such a procedure as a preventive one, especially since it is quite laborious. We also recommend that you perform this procedure first when buying a car with a mileage of more than 70-80 thousand kilometers or if there are specific signs of excessive filter contamination.

Choosing a fuel filter for Toyota Corolla

To search for non-original replacements, you need to focus on the following factory assembly numbers:

• 120 body, production from January 2002 to June 2004 - 77024-12010
• 120 body, production from June 2004 to February 2007 - 77024-02040
• 150 body - 77024-12030

The cardinal difference here is in the price: original filters for 120 body cost about 1,500 rubles, while for 150 body the price exceeds 4 thousand. Therefore, it is not surprising that for this particular model there is a more affordable non-original in the form of JS Asakashi FS21001 and Masuma MFF-T138.

For 120 bodies, non-original filters are difficult to find, but the price of the original is not so great.

You will also need a filter o-ring - its part number is 90301-04012.

Fuel filter replacement instructions

Before replacing the fuel filter, you need to drain the tank as much as possible, without bringing the level, of course, to a critical one - otherwise the fuel pump will have to be changed along with the filter. If you do not empty the tank, then when removing the fuel module, the risk of spilling gasoline into the passenger compartment is too great.

In the future, we will write about cars in the 150th body, since replacing the fuel filter with your own hands on both models is similar in principle, but here it is somewhat more complicated. Let's start by accessing the gas tank hatch, which is located under the back seat of the car.

On the 120 body, the hatch is round, glued to a non-drying mastic.

At 150 - egg-shaped, attached in exactly the same way.

Now you need to start the engine and at the same time disconnect the connector from the fuel pump - the engine will generate almost all the pressure in the line, and when the fuel supply pipe is disconnected, there will be no risk of getting a jet of fuel under pressure.

Disconnect the fuel supply pipes, fan and adsorber. Before this, the fuel pump cover should be washed - it is better to work with the fuel system with clean hands.

The fuel pump is held by a shaped nut. You can unscrew it without the original puller by inflicting a few gentle blows on the rib along the tangent - after that you can tighten it with your hands.

We remove the fuel pump, trying not to spill fuel into the passenger compartment.

Now it is necessary to separate the filter assembly from it - the order of operations is easy to understand by placing a new part next to it. Having pulled the pump itself out of the assembly, we change the sealing ring and the fuel receiver mesh on it.

We fix in place a new fine filter, connect the pressure pipe to it.

Now you can install the assembly in place, paying attention to the fact that it sits exactly before tightening the nut - otherwise the sealing ring of the cover will not be compressed tightly.

Toyota Corolla is the world's leading car sales leader. It is for this reason that she got into the Guinness Book of Records. Such demand was brought to her by fundamentality, ease of operation, as well as impressive characteristics.

Sedan Corolla 120

Cars of this brand are considered one of the most enduring in the world and rightfully top numerous reliability ratings. But, despite all these aspects, this car needs timely maintenance. In our article, we will conduct a detailed analysis of an important part of this process - replacing the fuel filter and the 150th body.

Hatch leading to the fuel tank

Changing gas filters is important to maintain engine power, avoid problems when starting it, and to extend the life of pistons, piston rings, connecting rods and pins.

Replacing the gas filter in is carried out independently, if the owner of the car has an idea about working with tools of medium complexity.

Spare parts and tools

Before changing the fuel filter to Corolla, you need to prepare. To do this, prepare the necessary tools and materials in advance. We will need:

• coarse gas filter;
• fine fuel filter;
• narrow slot screwdriver for fasteners;
• Phillips screwdriver.
• wrench for 8,

Also prepare a large amount of rags and a container of water.

Execution of work

The Corolla gas filter is located in the tank and is part of the fuel pump module, consisting of:

• fuel pump;
• primary gas filter - a component that cleans fuel from excess moisture and various impurities;
• final filter - a component that thoroughly filters fuel from smaller particles;
• float showing the amount of fuel.

fuel pump cover

Before starting work, it is necessary to drain the fuel from the system so that later it does not fill the car interior with it. To do this, pull the fuse from the fuse box, and leave the engine idling until the fuel pump and line are empty and the engine stalls. Next, open the gas tank cap to relieve pressure. It is also recommended to replace filters with a small amount of fuel in the tank.

Gasoline pump and filters assy

First you need to disconnect the negative terminal of the battery. Then we remove the rear seat, fixed with two latches and a guide. You need to do this with sharp movements. Under the seat is the gas tank cavity cover with wires connected to it. The cover is secured with sealant and lifted with a flat-tip screwdriver. This frees up the entrance to a small space above the tank, where the fuel system unit is installed. To avoid getting dirt into the tank, you need to clean it with a vacuum cleaner under the place where the seat was, and then above the tank itself.

Now it is possible to assess the degree of contamination of the tank and coarse mesh. The degree of contamination of the fine fuel filter cannot be seen.

The next task is to disassemble the fuel module. To do this, dismantle the float by bending the plastic latch. Then the mesh is removed and the fine filter is disconnected, which is fixed with a rubber gasket.

One latch

When disassembling an old gas filter, it is important not to lose the rubber bands, in case new ones were not purchased. The hardest thing is to remove the rubber band from the top of the gas tank.

We insert the rubber bands into the new filter element, similar to the location in the old one, and complete the structure. The coarse filter and the retaining ring become problematic.

Two more latches

Now we return all the details to their place in the sequence in which they were shot. Tighten the nuts again, attach the tubes. But before you put the seat in place, it is worth checking how the system works. To do this, insert the key into the ignition and turn it to the "ON" position, but without starting the car. The operation of the fuel pump should be audible. The sound should be familiar. The metal tank cap is installed using the same sealant, after which the rear seat can be installed in place.

Possible troubles and difficulties

After replacing and placing the fuel pump in the fuel tank, the car may not start the first time. The reason for this may be poor sealing of the fuel pipes, as a result of which the fuel pump does not create sufficient pressure in the line.

Leaky fuel pump pipes

When disconnecting the hoses from the body, you should be careful. The system is pressurized and fuel may splash into the passenger compartment or eyes. It is worth stocking up with a sufficient number of rags for cleaning.

It is also worth being attentive to fire and sparks near the work site, because. after removing the cap, gasoline vapors from the tank quickly fill the cabin.

Check for leaks prior to installation

How often to change

Signs of a clogged filter element

Corolla 120 station wagon

The need to change the fuel filter can be indicated by the operation of the car. Some of its features may indicate problems in the fuel pump. And so that each time you do not have to disassemble the fuel pump to check its serviceability, you need to pay attention to such violations in operation:

• it is difficult or impossible to start an unheated engine;
• at idle, the power unit is unstable;
• the car twitches while driving, slows down on its own;
• there is a feeling of "triple";
• deterioration of the dynamic properties of the vehicle.

The fuel filter in imported cars differs significantly from the filters of domestic VAZs. For a driver who has just moved to this foreign car, you need to know that Toyota Corolla has two fuel filters. The main one is located in the gas tank and is attached together with the fuel pump. It is he who plays the main role in cleaning the fuel and its further supply to the pump.

However, when the fuel filter ceases to perform its functions, this will certainly begin to affect the operation of the car. It can pull badly, it doesn’t start the first time, it picks up acceleration weakly. This significantly increases fuel consumption. If the filter is not replaced on time, the fuel pump may fail. This happens because it constantly pumps the necessary amount of fuel for the operation of the car, and a clogged filter will prevent it from doing so.

Replacing the main filter - follow the instructions

Replacing the fuel filter in a Toyota Corolla is a feasible task for every driver. In car dealerships, there is basically only an additional filter, which is located under the hood, so think about ordering the main device in advance. It is not worth saving on the purchase and it is better to purchase only the original. It will serve you much longer than the Chinese fake, which is now saturated with the auto parts market.

Before replacing, you will need not only the part itself, but also additional tools: a pair of screwdrivers and sealant, as well as open-end wrenches to replace the second filter. The main fuel filter in a Toyota Corolla is located under the rear seat in the fuel tank. This type of filter is called submersible. To replace it, you need to raise the rear seat, or even completely unscrew it for a while. Under the seat you will see a metal cover, the so-called hatch. Using a screwdriver, carefully pry it out, as it is attached to the sealant. When doing this, be careful not to damage the electrical wires.

Opening the cover, you will see a fuel pipe and a chip with wires. First of all, turn off the power plug. The next step is to disconnect the fuel pipe. There is an arrow on its plastic retainer that indicates the direction in which you need to scroll it - do this carefully so as not to break it. After disconnecting, gasoline may pour out, so substitute a rag or bottle. To prevent spilling of gasoline, before starting all work, it is necessary to remove the pump fuse from the mounting block.

The engine must be turned on. You have to wait until it dies down. These actions will lead to the fact that all the fuel that is in the tube will burn. Before removing the pump and filter, pay attention to its correct location in the tank - in the same way, you will need to put a new part back. Unscrew and remove the clamping ring, then carefully remove the pump with the filter - it is important not to damage or move the level float with the fuel grid.

The next step is to remove the part itself. To do this, turn the entire body over and carefully slide a few rivets, then remove the cover. Under the cover there will be a rubber gasket, which also needs to be removed. Then remove the metal snap ring that holds the fuel screen. If possible, replace it with a new one, or at least rinse well in water and let dry.

Then disconnect the pressure regulator - it will be quite difficult to do this, since it is located in the sealing gum. After that disconnect the fuel pump and sealing rings. Now take a new filter and assemble everything in reverse order. Before assembly, you can lubricate all rubber sealing joints with oil, this will greatly simplify the assembly process. Clean the hatch cover from the old sealant and apply a new one. It will be necessary to hold it under load for 10-15 minutes so that the sealant hardens.

Replacing the second filter is a simple task

After replacing the main filter, you can proceed to replace the second one. At this stage, everything is much easier. It is located under the hood, in the middle of the car frame. In Toyota Corolla, it is attached with two twists and a clamp. Carefully unscrew them, if necessary, treat the fasteners with WD-40 so as not to break the thread. Then unscrew the filter and replace it with a new one. Don't forget to replace the rubber o-rings that come with the kit. They are located in the fuel lines.

Toyota Corolla is a Japanese car, characterized by high workmanship, optimal dynamism, reliability and safety. In order for the operating parameters of the car to remain at the proper level, it needs timely and proper maintenance, replacement of consumables, tuning and diagnostics. One of the components that affects the overall performance is the Toyota Corolla fuel filter, the replacement of which can be carried out by the driver on his own, without contacting the service station.

Signs of clogging

In order for the fuel system of a car to work accurately, clean fuel must flow into it, without dust, abrasive particles, water and various impurities. To do this, all kinds of cleaning elements are installed in cars, the main of which is a filter for incoming fuel.

The fuel filter elements of Toyota Corolla cars in the E120 and E150 bodies are different in design, but the principle and procedure for replacing them are the same.

As a result of the work, the cleaning element is gradually clogged, which affects the overall performance of the car. If the high quality of the fuel entering the fuel pump is not ensured, the mechanism may fail. And this, as a rule, entails a violation in the operation of the motor itself.

The manufacturer recommends changing the Toyota Corolla fuel filter both with a body of 120 and with a body of 150 no later than every 60-80 thousand kilometers. But given the quality of gasoline in our country, it is better to do this even more often.

The following characteristic signs of unstable operation of the car testify to the clogging of the filter:

• a significant increase in the volume of fuel consumed in the absence of changes in the operating mode;
• acceleration became slower;
• with a decrease in engine speed, its power also decreases significantly;
• the car often stalls when stopped, for example, at a traffic light;
• startup becomes unstable, especially after a break of several hours;
• unstable operation of the transmission, lack of a clear response to gear shifting.

A clogged filter that damages the fuel system should be replaced as soon as possible.

Features of selection and replacement

In the auto parts market, the owner of a Corolla of both 2008 and later versions can be offered a choice of at least three types of filters - Chinese and Korean analog parts and originals. Original products, as a rule, cost an order of magnitude more expensive, but are of high quality and reliable. How much a Toyota owner is willing to pay for a new filter element depends on his budget.

After 2008, Toyota Corolla began to be equipped with fuel filters, which, if clogged, can be changed regardless of the gasoline pump, without resorting to replacing the entire module responsible for supplying fuel to the gas tank.

You should always be very careful in the selection process, and you need to purchase exactly the fuel filter for Toyota Corolla that suits the specific year of manufacture of the car and body type.

Replacement in 2007-2008 vehicles with 120 body

The average period at which the element will qualitatively filter fuel on Corolla E120 cars is 50 thousand km. But keep in mind that this parameter is calculated for Japanese roads, the quality of which is much higher than domestic ones. Therefore, in the case of using a car in our country, you should change the filter every time after a run of 25-30 thousand km.

In order for the replacement procedure to go quickly and without problems, you should prepare such a set of tools and other necessary items:

• a new fuel filter that will be installed to replace the old one (preferably original, although sometimes there are Chinese consumables that work well);

• new sealing rings (2 pieces);

• Phillips and flat type screwdrivers;
• rags;
• dishes for draining excess fuel.
  

First you need to remove the rear seats and remove their interior upholstery. Underneath is the fuel pump cover.

With a flat screwdriver, carefully, trying not to damage anything, it is necessary to remove the fuel pump cover.

After all this has been done, you should start the car a couple of times and let it stall so that all the gasoline that may be in the system is gone from it. Then you need to remove the battery terminals. After that, the pump itself is taken out, and it is inspected, the condition of the mesh for rough cleaning is assessed.

It is necessary to dismantle the float and remove the coarse fine cleaning elements, which we replace with new ones.

After installing new elements, reassemble in reverse order and install the gasoline pump in its place.

Replacement in a car with a body 150

To replace the fuel filter on a Toyota Corolla 150, you need the same set of tools, as well as new filters and o-rings. In this modification, the fuel pump cover is made of plastic and equipped with a rubber seal. To remove the fuel pump, it is necessary to turn the ring counterclockwise and loosen the seal. The further replacement process is the same as for the 120 body.

Conclusion

This replacement procedure is typical for various Coroll bodies and is applicable to cars up to and including 2004. The location of the filter element does not depend on whether it is Fielder or not, what engine is installed (1.6 l or another). It is necessary to change the fuel filter in a timely manner, this will help prolong the efficient operation of the engine, make the operation of the car comfortable and of high quality, and also prevent other problems and malfunctions in the fuel system.
