How to replace a Chevrolet Niva cooling radiator. Other components of the cooling system

The aluminum radiator has advantages such as:

1. Low price, which attracts many motorists.
2. Relatively light weight parts. But at the same time, aluminum cannot boast of high thermal conductivity, therefore, the thermodynamic instability of the material leads to corrosion.
3. Maintainability.

Copper radiator is not so popular, but we have more reasons stop the selection on it:

1. Corrosion resistance.
2. High efficiency of action.
3. Great level of thermal conductivity.
4. Strength and durability.

At the same time, the only drawback of copper radiators is their high cost, but the advantages described above cover it.

Since the radiator performs the function of protecting the engine, it must itself be High Quality and withstand temperature fluctuations. The price of a spare part varies widely and depends on various factors: material, quality, manufacturers.

How to replace a cooling radiator on a Chevrolet Niva

With visible damage, even without antifreeze leakage, the radiator needs to be replaced. Antifreeze is a liquid that cannot be frozen at sub-zero temperatures.
Replacing this spare part is a very laborious task, but, following the sequence of actions, any motorist will cope with it.

You will need:

1. Remove bumper.
2. If the car is equipped with air conditioning, then the air conditioning radiator should be removed.
3. Depressurize the air conditioning system.
4. Remove the cooling radiator.

Niva Chevrolet belongs to the ranks of SUVs, respectively, is operated in different weather and climatic conditions. Therefore, before making a choice of a radiator, weigh all the advantages and disadvantages of the product.

Hello! I really need step-by-step instructions for removing the stove radiator without. I have a Chevrolet Niva (Bertone Edition) with air conditioning, bought in 2010. Thank you! (Yuri)

Hello Yuri. Many nivovods face the need to replace the radiator. About how to replace the device without removing dashboard, we will explain further.

Device replacement

First you need to disconnect the battery terminal.

1. Dismantle the side panel, as well as the glove box, by unscrewing all the necessary screws.
2. Next, unscrew the bolt and dismantle the air duct located at the passenger's feet. Unscrew electronic system engine control, it will be easier.
3. Dismantle the airbag plug, which is mounted on four bolts from the inside. Next, cut out the plastic and remove the duct.
4. Now you need to remove the cabin filter element. Dismantle the so-called volute together with the damper body, the structure should be moved to the side. After that, disconnect the supply wires and dismantle the electric motor along with the snail.
5. Next, you will need to unscrew the evaporator, which is attached with two bolts to inside. In addition, disconnect the pipes together with their fastening device.
6. The bottom plates should be bent. The evaporator itself should be slightly moved to the side (to the right). Here it will be as careful as possible, in no case should a lot of force be applied so as not to damage the element. Press the evaporator to the floor vehicle then just pull it out.
7. The radiator hoses must be removed. If you see that they are in a deplorable state, then it is advisable to replace them immediately, then the pipes can be cut off. Besides, it will be much easier. The device mounting bolts must also be removed.
8. Then you just have to dismantle the element and replace it with a new one. All further assembly is carried out in reverse order. You need to wait a while for the noise to dry. Pay attention to the condition of all hoses and pipes, if you notice any flaws, we recommend that you change them immediately.

Video "How to change the radiator on a Chevrolet Niva with your own hands"

A detailed replacement process is presented in the video (auto video - Valery Pospelov).

Replacing the radiator on cars is rarely required. This mainly occurs when the system is depressurized as a result of damage. We will analyze in detail how to replace a defective part with a new one, what set of tools will be required to carry out this type of work, and how the work differs on cars with and without an air conditioning system.

First you need to make sure that the problem is in the faulty radiator. In some cases, coolant leaks may be due to burst pipes. If there is no visible damage and only traces of antifreeze indicate a leak, you can try to wash it. But this does not apply in cases where obvious damage is present, in this case urgent replacement is required.

Before starting work, it is necessary to take care of the presence of WD-40 fluid to unscrew the rusted bolts, it is also necessary to have a container with a volume of at least 5 liters to drain the used coolant. During operation, you will also need to drain the used fluid from the hydraulic booster.

Operating procedure.

For work you will need the following set of tools:

• antifreeze;
• sealant;
• head on 8, 10, 13, 17;
• Phillips screwdriver
• power steering fluid
• container for draining the coolant.

Replacing the radiator on a Chevrolet Niva.

After necessary equipment prepared, you must disconnect the battery, because during the repair process it is necessary to disconnect some electrical components of the system.

To provide access, it is best to remove the decorative grille from the bumper and unscrew the crankcase. Sometimes it is quite difficult to unscrew it, because the bolts holding it rust. In this case, you can spray them with WD-40, wait 10 minutes, after which it will be much easier to do. After removing the protection, you need to remove the engine mudguard, this will provide better visibility from the inspection hole.

At this stage, it is best to once again inspect the pipes leading to the radiator, since a leak may appear on their lower part, imperceptible in the normal state.

After that, we drain the antifreeze from the system.

During this, it is best to unscrew the lid on expansion tank and open the heater tap. To do this, we translate the stove regulator into the red zone. At the bottom of the radiator, we open a special valve that allows you to drain most of the liquid.

About 8 liters of antifreeze will fit in the cooling system of the Chevrolet Niva SUV, but some of it will remain in the system, so when choosing a container, you can get by with a container of 5-6 liters.

We remove the case air filter to allow access from above. Under it are pipes leading to the power steering radiator. When they are disconnected, a small amount of liquid may come out of them. If necessary, it can be reused, just pour it into a clean container.

After disconnecting the pipes, it is necessary to remove the power steering cooler. But it is worth remembering that this procedure is not required. It is only designed to increase the free space for installing a new radiator, so as not to damage its cells.

The radiator is attached with brackets at the top. For greater convenience, it is best to remove the brackets themselves.

We turn off the fans, they are attached with 6 nuts to the radiator. You do not need to remove them individually, it is better to dismantle the entire unit completely. After turning them off, you need to remove the last pipe.

In this case, each master acts in his own way. Some masters prefer to shoot front bumper, others simply bend the diffuser towards the engine to be able to remove the radiator.

Installation.

First you need to prepare new radiator. To do this, remove the rubber legs from the old one and put them on new part, since new radiators are not equipped with them. Next, we assemble in the reverse order. During installation, it is best to position the clamps so that they are as accessible as possible in case of the next replacement.

When assembling the power steering system, there is no need to pump fluid, if a small amount of air gets inside, it will come out after a while into the expansion tank. Therefore, after replacement, it is necessary to monitor the fluid level for some time and, if necessary, add it to the maximum mark.

After assembling the system, it is necessary to fill in new coolant. Must be filled out via expansion tank. It is important to start the engine after filling so that the pump works and wait until the engine warms up to operating temperature and the thermostat will open. At this point, the large circle will be open and you will need to add antifreeze to the system until right level.

All work on replacing the radiator is divided into several stages. If there is not enough time, and the car is needed during the day or due to
There is no time to do repairs, then it can be done in the evenings after work for several hours. If you replace it in the usual way with the removal of the panel, then the car will remain motionless until the panel is put in place, although most of the repairs on the Chevrolet Niva can be moved around, but you must remember to make sure that the level of antifreeze in the tank is normal.
You should pay attention to the fact that during operation there are a lot of bolts, and in order not to get confused, then which one, where the bolt comes from, it is desirable to mark them.

• A short screwdriver with a reverse, it will greatly help during work.
• T20 torex, and cross bit
• Electrical tape that should be wrapped around the bit and inserted into the key for seven, and wrapped with electrical tape,
• since there is one self-tapping screw, to which it is impossible to crawl with a simple screwdriver.
• Flat-blade screwdriver.
• Keys for ten, nineteen, twenty-four, and eight
• Pliers to remove the clamps on the nozzles
• Flashlight to have a stationary light inside the panel
• Silicone sealant, you will need it during assembly, but this is already a wish

First stage. We take the glovebox.

Unscrew the cover with right side from the glove compartment. To do this, all the screws that are visible on the tunnel and inside the glove compartment are unscrewed. The glove compartment on the lid on the underside has a pad that is held on by 3 screws, and on top closer to the handle by four. It should not be unscrewed, as it will not interfere.

The second stage, remove the airbag.

Remove the negative terminal from the battery so that the airbag does not work. From below, among the wires, we are looking for a red terminal. We take a flat screwdriver, the latch that is attached to the panel frame, hook it up and pull it all the way down. All, thus, we release the chip and disconnect it. The pillow block with a plug on the panel are one piece. With a key of ten, we unscrew the fastenings of the pillow to the frame, which is held on by two bolts. The plug on the panel is removed with a flat screwdriver, we press the latches from the bottom with our hand, and pull the pillows up.

The third stage, we remove the passenger air duct.

We hook the side plugs at the passenger grille with a screwdriver, and two self-tapping screws behind them. We pull out the grate towards ourselves, if it doesn’t go boldly pull it towards ourselves. We take out the air duct, peeling off the reinforced adhesive tape that tightens the air duct.

The fourth stage, remove the nozzles.

We get to the nozzles and inside we unscrew the self-tapping screw, after which we pull the nozzle towards us.

Fifth stage, remove the fuse box and the ECU.

Pulling out the air conditioning evaporator will most likely interfere with our brains. It is enough to remove them from this mount and just leave them hanging. You can do this later, but you will have to remove them anyway.
We unscrew the cover of the brains with a ten key, and unscrew the fastening bolts with a Phillips screwdriver. From the bundle of wires, two go to the body, this is a mass, they do not allow the ECU to be lowered low. Therefore, we unwind the electrical tape and bring these wires to the side.

The sixth stage, remove the snail.

It should be removed, after which we unscrew the four screws that attach the snail to the body. There is no need to remove the motor that is there. From the bottom of the stove you can clearly see the self-tapping screw, unscrew it, then inside the panel on the right, there is a self-tapping screw, a bat with a key for seven, (you can see how to do this in the picture above) unscrew it by sticking one hand into the hole where the airbag is with the key in the air duct hole on the passenger side. Thus, we twist with the right hand, and press with the left.
We bend the iron brackets into the salty cable that regulates the position of this damper, remove it by prying the casing latch with a narrow screwdriver.

The seventh stage, we disassemble the snail and take it out.

This is one of the most difficult moments. To remove the two halves, the bottom and top, you need to remove six latches. We pry off the upper ones with a flat screwdriver until they fly away, we already touch the rest by touch. After the latches have been removed, we separate the case into two parts by turning the upper part to the right.

The eighth stage, remove the air conditioner evaporator.

As a rule, the car can be equipped with air conditioning; without air conditioning, we skip this step. If the first option, then you should unscrew the air conditioner tubes. Freon will start to come out, it is better for them not to breathe. Nearby are a couple of studs with nuts, they are unscrewed together. Then remove the bolts that secure the evaporator housing. To the left of the nozzles there is one self-tapping screw, you can not notice it, and therefore if you do not unscrew it, there may be problems with removal. After all the manipulations, we shift the evaporator to the right, taking it out of the stove, pull it down a little and towards ourselves. We remove the front bracket from the left, removing it from the mount.

The ninth stage, we remove the stove radiator.

We remove the heater radiator, the heater radiator should be removed carefully, and it is better to lay a bag or oilcloth under it so that antifreeze does not get into the cabin. Preparing five liter canister or an eggplant, under antifreeze. We drill a hole in the bottom of the radiator, and drain the liquid into a container. Then unscrew the clamp from the nozzles, and two screws. After that, we pull out the radiator and pull out the remaining pipes, and we will see a leak on the radiator.

The tenth stage, replacing the radiator and pipes.

In this final step, we change the radiator or hose (pipes). We advise you to change everything, since the old ones do not know how long they last.

Thus, on the car, the Niva Shivrale was replaced, the radiator was made, we assemble everything in the reverse order!

Cabin heater - an eternal problem domestic cars. She is familiar to us from the “nines” and “eights”. Despite close cooperation with General Motors, the Chevrolet Niva SUV also has problems with the cabin heater. In particular, this is a radiator. In today's article, we will talk about how to replace the radiator of the Niva-Chevrolet stove with our own hands.

Symptoms

Determining this is easy enough. If the insides of the heat exchanger are clogged, the Chevrolet Niva heater simply will not work. From the deflectors will blow constantly cold air because antifreeze does not circulate inside. The stove simply has nowhere to take heat from.

But this malfunction can also occur due to a failed stove drive (especially if it is cable). Open the hood and check the fluid level in the expansion tank. If it is at a minimum, then there is a leak. It may be associated with a breakdown of the radiator cells. Often antifreeze flows directly into the cabin. Therefore, you will immediately notice a characteristic smell. The liquid itself will be oily, and greasy streaks will appear on the carpets.

What is needed for replacement?

So, first you need to choose a new heat exchanger. There are several manufacturers of stove radiators for the Chevrolet Niva on sale:

• DAAZ.
• "Luzar".
• "Craft".

Judging by the reviews, the best of them is DAAZ. Also given manufacturer works closely with certified services and dealers to warranty repair. The price of a new element is about 1600 rubles.

We also need thin foam rubber. It is necessary in order to reduce the gaps in the passage of air. Thanks to this "tuning", the flow will pass directly through the radiator, and not past it.

In addition, you will need a Phillips screwdriver to unscrew the interior elements and the heater pipe clamps.

Since coolant is used to operate the stove, it will certainly spill during dismantling. To avoid a flood in the cabin, we prepare a cut plastic bottle and pieces of polyethylene. Ideally, you need to drain the fluid completely from the system. At the end of the installation, fill it again through the expansion tank.

Getting Started

If the radiator of the Niva-Chevrolet stove is being replaced without air conditioning, you need to remove the glove compartment from passenger side. It is attached with screws. We put the latter in a separate box so as not to experience difficulties with installation.

If the radiator of the Niva-Chevrolet stove with air conditioning is being replaced, you will have to disassemble the front panel and part of the engine compartment.

So, let's start with the replacement. First, unscrew the glove compartment and remove it from the passenger compartment. Next, you need to remove the lower air duct, which blocks access to the radiator. For safety net, we put cardboard or polyethylene on the rugs.

Next, using a Phillips screwdriver, loosen the clamp securing the lower radiator pipe. Be careful - antifreeze may splash when disconnecting. Try to remove it carefully so that the coolant does not get on the skin and eyes. If the pipe is firmly seated in the groove, turn it clockwise and counterclockwise. At the next stage, unscrew the second pipe. It is also attached to the clamps. Next, unscrew a couple of screws that attach the radiator itself to the stove body.

Take the heat exchanger out. Get ready for difficulties. The radiator may hit the air duct. To remove it, you will need to bite off the plastic corner of the heat exchanger. It can also rest against the cover of the relay box. In this case, you will have to take the key to 8 and unscrew the block cover. This is the only way to make room for dismantling the radiator of the Chevrolet Niva stove.

Installation

So, the replacement of the Niva-Chevrolet stove radiator is almost completed. Now you need to install new element in reverse order. First you need to paste over it with a thin strip of foam rubber. It is better to use "Moment" or "Liquid Nails" glue for this. Next, with the help of a file, we bite off a plastic corner (in the same way as during dismantling). Installation can also be difficult. Often foam rubber clings to interior details.

Therefore, you need to apply dexterity and dexterity in order to place the element without damage in seat. Then we install pipes on the heat exchanger on both sides. We fasten the glove box and other interior parts. This completes the replacement of the Niva-Chevrolet stove radiator. It remains only to add antifreeze to the desired level in the expansion tank.

As a rule, the stove pipes fit quite tightly on the radiator. Experienced motorists recommend using Litol-24 grease. We coat it inner part pipe and install everything in place. The rubber band should go in with no effort. Additionally, lithol will provide us with tightness and prevent leaks of antifreeze at the joints.

So, we found out how to replace the radiator of the Niva-Chevrolet stove with our own hands.
