Radiator VAZ-2106: replacement of the element

The fuel-air mixture generates a huge amount of heat during combustion. Accordingly, for normal operation of the engine, a good heat sink is needed. This function is performed by the cooling radiator. VAZ-2106 is also equipped with them. But sometimes it happens that the part fails. How to determine the breakdown and replace this element yourself? Let's consider.

Why does this happen?

The main reason that the VAZ-2106 radiator has become unusable is leakage or breakdowns inside the element. If you notice that the level of antifreeze began to fall, and after a short parking under the machine a puddle with a liquid formed, most likely a breakdown occurred in the cooling system. It's not recommended to ride with such a malfunction. Some owners prefer to repair the old element with argon welding. But not in all cases it is possible (especially if it's a copper VAZ-2106 radiator ). And not every master will guarantee trouble-free operation of the restored heat exchanger. Therefore, the best way to solve the problem is to replace the radiator. VAZ-2106 is a very repairable car. Therefore, it is easy to fix it yourself. Below we will tell you how to do it.

Instruments

What tools do we need to replace? To remove and install the radiator, we need a "10" head, an extension cord, a ratchet, a cross and a flat screwdriver. The presence of a viewing pit is not necessary.

Step 1 - merge antifreeze

The first step is to drain the old coolant. An important point - to produce coolant discharge is required only "on cold". If the car has just been driving recently, wait until the engine has cooled down. So, we set the car on a flat surface (you can with a slight inclination upwards). In the salon we cover the cock, which serves the antifreeze on the radiator of the heater. VAZ-2106 continues to stand still. After that, open the hood and unscrew the cap of the expansion tank. This is necessary in order to eliminate the vacuum in the system. Further we substitute capacity on 5-7 liters under a drain aperture. You can use an ordinary pelvis, as in the photo below. Unscrew the plug (it is in the area of the cylinder block) and wait until the antifreeze completely leaves the engine. This will take about five minutes. After that, tighten the lid and other openings. Proceed to the next stage.

Step 2 - dismantling the SOD fan assembly with the electric motor and the casing

This is an obligatory stage. How to extract this mechanism? For convenience, first remove the terminals and take out the battery. After that, disconnect the harness in the area of the left headlamp. We take out the power supply. We get the holders of the fan switch. To do this, squeeze the part with your fingers on the sides and remove it from the hole in the casing. We unscrew the bolts of the casing itself. The last element is extracted together with the fan outside (gets to the right upwards). Often it is contaminated, so cleaning it will be superfluous.

Step Three - remove the hinged

Now we need to extract all the hinged elements. So, we need to loosen the hose clamp of the expansion tank and the nozzles that go to the engine of the car. Usually they are twisted with a Phillips screwdriver. If the compound is oxidized, a small spanner can be used. First, take out the expansion tank hose, then the upper radiator hose. Now it is necessary to disconnect the wires from the fan switch. After that the carabiner or spanner is required to unscrew the fastening bolts of the radiator itself. The element is attached to the left and right. Now you can safely pull out the radiator VAZ-2106 outside. In its place, install a new heat exchanger. Try to place it as neatly as possible, so as not to damage copper or aluminum honeycombs. Otherwise, the radiator breakdown will occur before it is installed on the vehicle. Reassemble in the reverse order.

Fill the antifreeze

Now it only remains to fill the system with a new coolant. To do this, unscrew the cap of the expansion tank and fill the antifreeze with a technological watering can. Try to dose the flow of fluid. Do not pour too much antifreeze at once - there is a risk of air bubbles. Also, to avoid venting the system, press down repeatedly on the bypass and outlet pipe. Topping up the antifreeze to the desired level, tighten the lid and start the engine. Having warmed up to operating temperatures, a fan must start working. If it does not spin, check that it is correctly installed. After a day, check the level of antifreeze. If necessary, top up it to the desired mark. If not available, dilute it with distilled water (but do not mix different brands of coolant).

Helpful Tips

It often happens that if you install a new radiator, VAZ-2106 starts to lose the antifreeze. And it follows not because of a breakdown, but because of poorly fixed nozzles. Experienced car owners recommend to handle the pipes with silicone sealant and install them on new yokes. By the way, the hoses themselves should not be hard or pinched. If so, it is better to replace them with new ones. Also, cracks on the nozzles are not allowed. The repair kit is inexpensive, so it is better to stock up with new items in advance. Also, during the replacement of the radiator, it is recommended to check the condition of the heat exchanger supports. If they are badly worn, replace them too.

What if the antifreeze became brown?

In addition to leaks, owners are faced with a phenomenon such as a discoloration of the coolant. What is the reason? Whether to change anew the radiator VAZ-2106? The reason is the low quality of the antifreeze. The change in color indicates that there are no special additives in the liquid - corrosion inhibitors. Such a liquid is falsified and is not subject to exploitation. Buy only quality antifreeze.

Conclusion

So, we found out how to replace the VAZ-2106 cooling radiator. As you can see, this procedure can be performed independently with a minimum set of tools. By the way, the cost of a new radiator for the "six" (aluminum, produced by DAAZ), together with the clamps and branch pipes, is no more than 2.5 thousand rubles.
