DIY repair of a vaz 2106 water pump

If, during the operation of the VAZ 2106 engine, extraneous noise is heard from the water pump (pump) or a leak appears, then this part must be replaced. In most cases, it is a complete replacement that is made, and not repair, since the cost of the part is not so high, only about 600 rubles.

So, to perform this repair, we need the following set of tools:

1. Ratchet small and medium
2. Heads 10 and 13
3. Slim extension cord
4. Screwdriver
5. Open-end or box spanner 13

Now below we will analyze in more detail the procedure for removing and installing the pump. The first step is to unscrew the clamps securing the coolant supply pipes:

Then disconnect the pipe from the water pump:

Now you need to unscrew the two nuts securing the metal tube on the left side, which supplies the antifreeze (antifreeze) to the interior heater system (stove radiator):

And then we remove the tube from the studs, pulling it off with a little effort and pulling it to the side, as shown in the photo below:

Then you need to unscrew the three bolts securing the pump to the VAZ 2106 engine block. One of which is located at the very top in the center:

And two bolts still attach the VAZ 2106 water pump from below, this is clearly shown below:

Then you can safely take the pump out:

If necessary, we buy a new pump and install it in a strictly reverse order, installing all the removed parts in their places.

Everyone knows that any engine in which there are moving parts is inherent in friction as an integral characteristic. In an automobile engine, which is an internal combustion engine, the source of heat that must be removed is not only friction, but also the bursts of combustible fuel.

To reduce the temperature, lubrication of rubbing surfaces is used, which significantly reduces the temperature, and a cooling system, the main heat exchanger of which is a VAZ 2107 radiator.

But the radiator will be absolutely useless if there is no coolant flow through it. This current provides the "heart" of the VAZ 2107 cooling system - a water pump, or pump.

The pump is essentially a multi-blade impeller of a centrifugal type. It consists of a cover and a shaft. As a rule, the repair of a water pump is associated with two malfunctions, which, in principle, are easily determined:

• There is a coolant leak. This can be seen by a puddle under the car in the area of ​​the hood, by a rapid decrease in the level of coolant in the expansion tank, or even by a fountain splashing from the pump under the hood lid (if you open the hood with the engine running). This situation is the most unfavorable, since if repairs are not carried out on time, you can get a short circuit of high-voltage wires, fill the breaker-distributor, and even cause a fire in the engine compartment of the VAZ 2107. This is most often the fault of the leaking oil seal (8).
• Noise is heard during pump operation. In this case, the bearings on the shaft of the water pump (7) are faulty, since it usually works completely silently.
• There may be a situation where pump repair is not required. For example, the driver notices that the engine temperature is “on the red scale”. But it turns out that the sensor showing the voltage output by the generator also shows that the generator is "dead". It turns out that it is just enough to tighten the generator drive belt, since both the pump and the VAZ 2107 generator are on the same drive.

For effective injection of antifreeze into the cooling system, the gap between the impeller and the casing wall should be within 0.9 - 1.3 mm. In the event that the gap is too large, then the pump will poorly pump the antifreeze. If the gap is small, the impeller blades may break.

Many car enthusiasts believe that changing the water pump is better than disassembling it. In any case, you decide to repair the pump or replace it, you first need to remove it from the engine.

How to remove the pump?

• All work must be done "dry", that is, after the liquid has been drained from the cooling system of the VAZ 2107 (from the radiator and cylinder block);
• After that, we remove the generator drive belt, take the 17 key (the end key is better) and unscrew the generator strip fasteners, and then remove it from the generator:
  
• Then, holding the pulley with a screwdriver (so that it does not turn) using a 13 key, first we loosen it, and then we unscrew the three bolts of its fastening:
  
• We got to the pump. We take a 13 socket wrench and unscrew the nuts from its cover. There are 4 of them:
  
• Now, carefully, taking a mallet-type hammer (so that there is an elastic firing pin), tap the pump cover around the perimeter, and then remove the pump from the studs. The pump is removed.
• Attention! It is recommended that after removing the VAZ 2107 pump, in any case, change the cover gasket to a new one.

The installation of a new pump (or an old one, after the pump has been repaired) is carried out in the reverse order.

In conclusion, it should be said that the pump and its blades can be covered with "scale" from the old antifreeze. It can be removed using phosphoric acid, or by shaking the pump in Coca-Cola.

The pump is one of the elements of the cooling system of the VAZ 2106 car, located in the water pump. Its purpose is to force the coolant to move throughout the entire engine cooling system. This part is considered very important, since if it stops working, the cylinder block stops cooling and can jam.

Any pump can last a long time. The term of its operation directly depends on the conditions of its operation. Sometimes, the breakdown is minor and may need to be repaired. For example, a defective oil seal or bearing can be replaced.

However, there are situations when a part cannot be repaired, and it needs to be replaced. Moreover, replacing the pump on a VAZ 2106 car should be urgent, since if this breakdown is ignored, the engine may overheat and ultimately jam.
