Kia Rio III was equipped with both 1.2, 1.4 or 1.6 liter petrol engines and diesel units (1.1, 1.4 CRDI). Due to the greater distribution of cars with gasoline units, do-it-yourself replacement of the Kia Rio 3 fuel filter will be considered using the most popular 1.4-liter power unit as an example.
How often do you need to replace
According to the manufacturer's prescribed routine maintenance, the fuel filter should be changed every 60 thousand km. During the warranty period of the car for 15 and 30 thousand km, if necessary, the coarse filter element is inspected and cleaned.
The car with lost dynamic characteristics, problems with starting the engine itself can tell you how much to change the TF. But the exact conclusion of the fault of the power supply system in interruptions in engine operation can only be obtained after measuring the fuel pressure in the rail. If the measured value is significantly less than 345 kPa, then the problem is the loss of performance of the fuel pump or a clogged TF.
Choosing a fuel filter for Kia Rio 3
Special requirements for the choice of filter elements should be made only if your Rio is equipped with a Diesel cycle engine or a gasoline unit with direct injection (for example, 1.6 G4FD, which is a GDI series engine). It makes no sense for owners of cars with atmospheric internal combustion engines and distribution injection on valves to prefer original products instead of, for example, Bosch filters.
According to the Hyundai / Kia spare parts catalog, the coarse strainer has a number - 31090-1G000, and the filter element for fine particles - 31112-1G000.
Where is the phone on Kia Rio III
The coarse and fine filter elements on the Kia Rio III are located inside the fuel tank, so the fuel module will need to be dismantled to replace it.
From the tool, you will need cap heads for 8 and 12, a knob or a ratchet with a small extension. Also, do not do without a sharp knife and pliers.
Before starting self-replacement, relieve pressure in the fuel line. To do this, just start the engine, then remove the fuel pump fuse (F3, 15A) from the mounting block in the engine compartment and wait until the engine stalls.
Replacing the fuel filter Kia Rio 3
- Remove the rear seat, as this is the only way you will gain access to the fuel module. It is most convenient to unscrew the seat with a socket head for 12 with an extension cord. The mounting brackets are located between the cushion and the back of the rear row of seats. After unscrewing the bolts, lift the pillow (it is held on by 2 latches), after which it can be moved away and completely removed.
- You will have access to the fuel section hatch, which is attached to the car body with a sealant. The hatch can be removed by separating the sealant from the body with a knife. If the work is carried out in the cold season, the perimeter sealant can be slightly warmed up with a building hair dryer.
- Be sure to clean the hose attachment points, the seat of the fuel module from dust and dirt.
- Remove the fuel module power connector (the ignition key must not be in the On position).
- Remove the gasoline vapor ventilation hose. Using pliers, squeeze the ends of the self-tightening clamp and slide it behind the fitting. If the procedure is performed in frost, be careful when removing the hose, since the fitting, like the module itself, is made of plastic.
- By pressing the latch, dismantle the fuel hose going to the ramp. Also release it from the plastic holder.
- Using an 8 socket and extension, unscrew the module cover stop plate.
- Remove the fuel module. This should be done as carefully as possible so as not to damage the FLS float.
Dismantling the module and installing a new fuel filter
- Disconnect power connectors.
- Using a slotted screwdriver, pry off the LLS retainer, then slide the sensor and remove it from its seat together with the float and connector.
- Dismantle the locking clips of the corrugated fuel supply hose.
- Pull out the outlet tube tip and O-ring. Do the same for the inlet fitting.
- Press the latches on the top of the fuel module, after which the cover and glass can be separated.
- Pry off the two plastic clips on the cup body and remove the filter element housing holding the fuel pump and pressure regulator.
- The fuel pump inside the housing also rests on the latches.
- The coarse filter is fixed to the fuel pump with a lock washer.
- Disconnect the "-" terminal of the fuel pressure regulator.
- Remove the rubber seal from the fuel return fitting.
- The fuel regulator is held by a plastic retainer with 2 latches (do not forget to install the plastic thrust ring and rubber gasket during assembly).
- Remove the fuel drain pipe from the filter housing.
Before installing a new filter, put the O-rings on the inlet and outlet fittings. After replacing the fuel filter on the Kia Rio 3 yourself and assembling all the components in the reverse order to removal, turn on the ignition several times to make sure the connections are tight and fill the system with gasoline (do not forget the fuse).
Kia Rio (2012-2013) is one of the most common car service procedures. The task of the fuel cleaning element is to protect the power unit from clogging and rust. During the passage through the filter material, the fuel undergoes mechanical cleaning from impurities, which significantly extends the life of the engine.
According to experts, there are about one milligram of all kinds of impurities in a liter of fuel. During fuel filtration, dirt and dust particles are almost completely removed, which are very often found in the containers in which it is stored. The fuel is also cleaned from resins formed during chemical reactions and condensate, snowflakes and raindrops that enter the gas tank during refueling.
Attention! During disassembly, be sure to pay attention to the position of the float indicating the fuel level, use any impromptu stand for this.

How to choose a fuel filter?
When choosing a fuel purifier for the Kia Rio, it is best to seek help from a selection professional or look at the instructions that come with the car. Various modifications of this brand of car are distinguished by small design features that also affect the fuel purifier.
No need to try to find an identical fuel filter for the Kia Rio on your own, because if you can find an identical housing model with the same threaded connection, this does not mean that the rest of the parameters will also work. It is necessary to take into account pressure indicators, throughput, the presence of valves, or vice versa, their absence.
- 31112-1G000 - Fine fuel cleaning element.
- 31090-1G000 - Coarse fuel cleaning element.
We carry out a replacement
The following symptoms may be prerequisites for replacing the Kia Rio fuel purifier:
- high noise during operation of the fuel pump;
- jerks appear at high speeds, which gradually become more frequent, and also appear at low speeds.
What will be needed?
- new fuel barrier;
- Phillips screwdriver;
- flat screwdriver;
- pliers;
- a set of keys;
- sealant;
- spray for cleaning the carburetor.
Steps
The fuel system designs of the Kia Rio 2012 and 2013 are very similar, so the replacement process is almost identical.
- We remove the rear seat of the Kia Rio - for this you need to unscrew the bolts with a 12 wrench.
- We remove the plastic protection - it usually sits on the sealant and, in order to remove it, you need to pry it with a screwdriver.
Opens access to a small hatch, fastened with self-tapping screws.
- The fuel system is under pressure, so for further work you need to reset it. We start the engine, and with the help of a latch, turn off the pump power block.
- We wipe the cover from debris and sand, but it is better to use a vacuum cleaner.
- We remove the fuel supply hoses, while pre-clamping the clamps with pliers. There should always be a rag nearby, because a small amount of gasoline may leak from the hose.
- Using a Phillips screwdriver, unscrew the bolts securing the pump.
- We remove the ring and slowly pull out the filter element from the glass, carefully watch so that the gasoline that remains in the pump glass does not spill.
- We fix the position of the fuel level float.
- Using a flathead screwdriver, pry off the retainers and disconnect the tubes.
- Slowly we remove the plastic latch, while freeing the guides so that we can remove them with the lid. We remove the fuel cleaning element together with the pump from the glass.
- We disconnect the negative contact, while the screwdriver remains between the fuel cleaner ring and the motor latches - this will provide an opportunity to disconnect it.
- Remove the metal valve.
- We remove the rubber o-rings from the old fuel filter.
- We put a new valve in a new cleaning barrier.
- We loosen the latches, remove the plastic part, then the o-rings.
- We put on a new filter barrier.
- We begin the assembly by installing the motor on a new filter and fixing the nozzles with latches.
- We put the fuel filter in a glass.
- We put the hatch in place, fix it with bolts and connect the chip.
- We put the assembled pump in the tank.
- Lubricate the edges of the protective cover with sealant and put it in place.
Problems that may arise after replacement, and methods for their elimination
After changing the cleaning barrier, many often face the same problem - the car does not want to start or starts very poorly.
First you need to check the removed fuel filter - it is likely that you forgot the o-ring on it. In this case, the fuel flows back and the pump needs to be re-injected, which causes complications with starting the engine. If the old filter element remains, and the ring is on it, then you will need to disassemble everything again in order to put the ring in place. If the seal is damaged or missing, you need to buy a new one.
The quality of the refueling fuel has a huge impact on the time to replace the fuel filter. If you often fill in low-quality contaminated fuel with a significant proportion of various impurities, the filter will become clogged much earlier.
Diesel-powered engines require filter replacement much more frequently than gasoline-powered ones.
The fuel filter is a part that requires fairly frequent replacement. This need is due to the following factors:
- the filter, in principle, should be changed approximately every 30 thousand km, these are the recommendations of the manufacturers, which should be followed for normal and durable operation of the vehicle;
- poor quality of gasoline sold in the territory of the Russian Federation leads to rapid clogging of the filter component.
If you neglect the timely replacement of this important part of the fuel system, you can get serious problems with the engine, the repair of which will cost much more than the elementary procedure for installing a new filter. It can be carried out by anyone who knows how to hold a screwdriver in their hands.
For example, replacing a fuel filter on a Kia Rio 3 will not be difficult. This will require only new parts, minimal skills in car repair. A viewing hole or overpass is not needed.
The role of the filter in the Kia Rio fuel system
The normal operation of the engine, and, accordingly, the entire car, depends on the serviceability of all components of the fuel system. In turn, the filter component plays a crucial role in the functioning of the entire system. He is responsible for cleaning the combustible mixture before it enters the unit.
Unfortunately, not everyone knows that even expensive brands of gasoline are far from ideal quality, and the purpose of the filter is to eliminate these shortcomings of the product. Litter and all kinds of impurities settle on the filter component of the part. As a result, it becomes clogged and needs to be replaced. The fuel passing through the filter is no longer properly cleaned, and unwanted components enter the unit.
They settle on the inner walls of the engine, as a result, the nozzles are partially clogged, the fuel is sprayed poorly. As a result, the motor starts to work unevenly, gasoline consumption increases significantly.
This is just the beginning of problems in the operation of the car with a clogged fuel filter. A long ride without replacing this part can destroy the car unit, which for cars like the Kia Rio will entail significant costs.
Important! This part for Kia Rio is inexpensive, so its timely replacement will not entail significant costs.
Why is fuel not getting to the engine?
There are two reasons why gasoline stops flowing into the unit:
- empty fuel tank. When the liquid level indicator in the tank does not work, gasoline can run out right while driving;
- clogged nozzles. In this case, the gasoline entering the fuel system is not sprayed inside the engine.
This is a consequence of a clogged filter component. As a result of its clogging, a low-quality combustible mixture enters the nozzles. The extra elements in it, that is, garbage, clog the thin channels of the nozzles. With significant pollution, they completely stop spraying gasoline in the injector. In this case, you will have to entrust their cleaning to a professional, which will entail additional costs.
The location of the cleaning filters in the Kia Rio fuel system
Gasoline cleaning in the Kia Rio fuel system occurs in two stages: the first is with a coarse filter. It is installed in front of the main filter. Most often, the second cleaning element requires replacement, this is a fine filter. It is he who filters gasoline before it enters the injector nozzles.
Important! Do not wait for the final clogging of the filters. It is better to change them in advance even before the pollution has not affected the operation of the unit.
Filter replacement
Replacing the fuel filter on a Kia Rio at a service station will cost a lot, since the dismantling of this part is associated with the dismantling of the rear seat. It is for this reason that the owners of the third generation Kia Rio prefer to perform the procedure on their own.
Important! It is worth buying a replacement part from official Kia dealers. since cheaper options can be very inferior to the originals in quality.
Dismantling
Replacing the fuel filter on the Kia Rio begins with the dismantling of the obsolete part. At this stage, we act according to the instructions:
After that, you should change the old Kia Rio filter to a new one and assemble the module in the reverse order. After that, the metal cover protecting the filter is put on again. The hose clamp must be clamped as tight as possible. Do not forget to put the fuel tank cap on the sealant. All actions usually take no more than an hour. The main thing is to follow clear instructions for performing work.
Important! To properly disassemble the Kia Rio 3 module, you need to look at the instructions for the car.
Car owners, not only KIA Rio, are forced to strictly comply with the regulations for the use of cars and regularly change the oil and filter elements. According to TO, every 60,000 km of run are accompanied by similar procedures. This article will discuss how to replace the fuel filter of KIA Rio models from 2005 to 2013.
When replacing, motorists are faced with the problem of cars of this brand: the KIA Rio fuel filter is located in a hard-to-reach place - under the bottom.
And this is only for the first models. Installing a new filter with your own hands in the case of owning a KIA Rio 2012,2010,2014,2011,2013 is more complicated.
However, they still carry it out themselves for a number of reasons:
- Budget savings. The service center overcharges for basic, do-it-yourself services. This problem exists not only for the KIA Rio model, but due to the complexity of replacing it, it is more acute.
- Build Quality Confidence. Yes, most owners are not specialists in assembling and installing parts. But a wide selection of instructions of a different nature will allow you to take an accelerated course of study. Thanks to the fact that you will do everything yourself, the result will not be in doubt.
- Increasing repair skills. Once you install it yourself, you can do it in the future. This may come in handy in an emergency. In addition, the more knowledge about your own Kia Rio car, the better.
However, there are also significant downsides. If the following points scare you, it is better to contact a KIA Rio specialist:
- High probability of error
- The impact of defects on the entire operation of the car
- Replacement duration
- Fire risk
- Difficulty in loosening fasteners.
More often, savings are put above the waste of time and they decide to change the KIA Rio filter without the help of specialists.
Updating filters on older models
As already mentioned, for older models, the filter is located under the bottom. It is necessary to use special tools: a lift or a flyover. Difficulties can arise even at the stage of loosening the fasteners, so be prepared to use the jack fully and do repairs for a long time.
The KIA Rio mounts require moistening with special liquids so that they can then be removed and penetrated to the area where the fuel filter is located. The deoxidization of the elements takes a short time, but it also requires patience. The accumulated dust and dirt prevents the bolts from moving away from the part. You can pre-remove it with other tools, and then the replacement will be faster.
The replacement process itself will take the owner a quarter of an hour with proper skill and preparation.
The location of the filter under the bottom exposes it to danger, especially the likelihood of fuel leakage. After the repair, you need to check the car by conducting a kind of test drive for 20 minutes. During this time, you will notice if there is a leak.
Important! Be sure to check the reliability of fastening. After that, without leaving the overpass, start the KIA Rio engine, let it run for 10 minutes to make sure there is no fuel leakage.
Repair of modern models
As for the KIA Rio 2012,2010,2014,2011,2013 models, it is even more difficult to change. The fuel filter has been moved to the tank, making it easier to access. It is especially easy to replace on JB models where a jack is not needed.
The list of tools is expanding:
- sealant
- A set of keys of various sizes
- Pliers
- Screwdriver Set
The difficulty is that the replacement can take more than an hour if you have not done it before. The step-by-step algorithm is more complicated than previous models:
- Loosen the rear seat anchors located between the seat and backrest.
- Use a screwdriver to remove the sealant from the protection element so that it can then be removed
- Clean the surface of the hatch that has opened to you, from where remove the self-tapping screws.
Important! The fuel tank is under pressure!
To get rid of it, start the KIA Rio and remove the electronic connector and sunroof connections.
- Remove the hoses intended for supplying gasoline. You should be careful with their removal, because there is still gasoline inside
- Pull the pump out of the mountings
- Take out the filter element Kia Rio
- Release all fasteners and connectors.
When you replace the fuel filter, do the reverse procedure, but do not forget one thing: rubber elements of KIA Rio 2012, 2010, 2014, 2011, 2013 cars, as well as models from 2005 - 2009, are subject to replacement th year.
The higher the quality of the fuel, the more efficient the engine is and the higher its resource. This is clear to everyone, but not everyone is responsible for the choice of gasoline, relying on the decency of oil companies and gas stations. Poor-quality gasoline can ruin a modern engine for literally 20-30 thousand, especially such as the third generation Kia Rio. No, it cannot be called unreliable, but it was designed to work on normal fuel.
That is why timely replacement of the fuel filter can extend the life of the engine. How to change the fuel filter for Kia Rio 3, which filter is better to choose, how much it will cost and when to replace it - we will analyze all these nuances right now.
How to check when to change and where is the fuel filter on Kia Rio 3
Continuing the tradition of almost all modern fuel-injected vehicles, the 1.4-liter engine of the Gamma family receives gasoline already cleaned and at the right pressure in the fuel rail. And the quality of cleaning depends on when to change the fuel filter on the Rio 3
The replacement of the fuel filter for Kia Rio 3 is carried out, according to the maintenance regulations, every 60,000 km or every four years. But given the quality of our fuel and the amount of dust on the roads, experienced drivers try to change both filters more often - about once every 40-45 thousand, or even more often.
Fine filter Kia Rio 3
The main indicator of the health of the power system is considered to be the correct pressure in the system. If the pressure is below normal, we will see all the symptoms characteristic of fuel pump problems, but rather fuel filters:
Coarse strainer Pump failure and clogged filters lead to a lean mixture, and this in turn causes all of the above symptoms. Not only is driving with a clogged filter or a faulty pump less fun, it's also dangerous for the engine. If so, we check the operation of the system.
How to check the pressure in the Kia Rio 3 power system
There is nothing difficult in checking the pressure. You just need to have a short hose, a tee and a pressure gauge with measurement limits of at least 5 kgf / cm². Checking the pressure in the system is carried out in several stages:
- We check the tightness of the fuel line, gasoline is not leaking anywhere.
- We check the contacts on the fuel system devices.
- We turn on the ignition and listen - the fuel pump should turn on. This will happen if we have not started the engine for several hours. If the motor was started and the pump is silent - it is necessary, it maintains pressure for some time after the engine is turned off.
- Relieve pressure in the fuel system. (We will describe how to relieve pressure below).
- We connect a tee with a pressure gauge in the gap between the fuel line and the inlet fitting of the ramp.
- We start the engine and look at the pressure gauge. At idle, the pressure rate is 3.45-3.55 kgf / cm². If the pressure is less, we check the pump and filter, as well as the fuel pressure regulator. All this economy is located in the fuel module.
Fuel system pressure After measuring, we release the pressure again, remove the pressure gauge and install everything in place.
The fuel module is a collapsible unit that includes a coarse fuel filter (mesh), a fine filter, an electric fuel pump, a pressure regulator and a fuel gauge sensor.
Choosing fuel filters for Kia Rio 3. Which one is better, part numbers and prices
Having saved on a good filter, we run the risk of forking out for the replacement of nozzles, candles and piston
The manufacturer insists that we use only original fuel filters. They have the following catalog numbers, fine filter:
Coarse filter, mesh:
Remove and change the fuel filter on the Kia Rio. How to relieve rail pressure
The job of changing the filters on Rio 3 is not particularly difficult and we will spend no more than two hours on it if we collect all the tools and consumables. Everything will work out if we are careful and follow the instructions below.
First you need to relieve the pressure in the fuel system, since it is strictly forbidden to depressurize the fuel line under pressure. The pressure is released easily. To do this, we find the fuel pump relay in the mounting block, which is located under the hood. The relay we need is the last one in the left corner. We take out the relay from the board and start the engine.
It will idle until it has exhausted all the fuel from the system and the pressure drops. Now you can remove the fuel module.
We act like this:
- Remove the negative terminal from the battery.
- Remove the rear seat cushion. To do this, unscrew the bolt with a 12 head and pull the seat up towards you. We remove it from the salon.
- We find the plastic cover of the fuel pump hatch, pry it with a flat screwdriver and carefully remove it.
- Disconnect the contact terminal from the pump connector.
- Using pliers, open the spring clamp and remove the vapor supply hose to the adsorber.
- We press the latches on the tip of the fuel intake pipe and remove it from the fitting.
- Remove the tube holder from the bracket on the module cover.
- With a head of 8, we unscrew the clamping screws around the perimeter. There should be eight.
- Remove the clamping washer.
- We carefully take out the module assembly, trying not to damage the float leash.
- Now carefully remove the sealing ring from the gutter in the tank.
- Disconnect the fuel gauge wiring harness...
- pulling the wires out...
- ... pry the retainer with a flat screwdriver ...
- ... and remove the sensor by pulling it down along the guides.
- Remove the fuel pump power wires by unfastening the latch.
- With the same screwdriver, carefully pry off the retainer of the gasoline supply hose from the filter to the module.
- We get the fixer.
- Remove the hose tip, do not lose the rubber seal.
- In the same way, remove this hose from the filter fitting.
- Loosen the guide clamps on the module body with a screwdriver.
- Separate the cover from the body.
- On the module case we pry two clamps ...
- ... and take out the filters, pump and pressure regulator assembly.
- Loosen two fasteners at the top.
- Carefully remove the pump and tube.
- We hook the stopper on the grid ...
