Replacing the coolant on the VAZ 2110-2112

I don't know why, but even many experienced owners drive their cars for more than 100 kilometers and never replace antifreeze or antifreeze (depending on what is filled) during this period. In fact, this fluid must be changed every 000 years or the vehicle's mileage of 2 km, whichever comes first.

If you do not change the coolant in a timely manner, then corrosion may appear in the channels of the block and the cylinder head ahead of time and the engine resource will, of course, be reduced. This is especially true for the cylinder head. Quite often I had to disassemble the motors and look at the cooling channels in the cylinder head eaten by corrosion. After such a picture, it becomes scary for your car and you will definitely not forget to change the antifreeze on time.

So, below I will give a more detailed report on the implementation of this work, as well as provide a list of the required tools:

Head for 10 and 13
Ratchet
Phillips screwdriver
Keys for 13 and 17 (provided that you have a 2111 engine and you have to remove the ignition module)

I have already said above, but it is better to repeat myself. If you have a 2110-2112 engine, then the antifreeze drain plug, which is located in the block, is free and can be done without any problems. If the engine model is 2111, then an ignition module is installed there, respectively, it will have to be removed first. Here is its location (below the 4th cylinder):

After it is removed and set aside, in order to avoid flooding with antifreeze, you can proceed to further work. We unscrew the front part of the engine crankcase so that you can substitute the container under the radiator drain hole.

Now we unscrew the plug of the expansion tank, then the plug in the engine block and the radiator, of course, you first need to substitute a container of the required volume under each drain hole.

Here is the plug in the block after unscrewing:

But on the radiator:

It is worth noting that when draining the coolant on the VAZ 2110-2112, the car must be on a flat, flat surface. After all the antifreeze has drained, you can screw the plug into the cylinder block and radiator into place. Then you can start replacing the coolant. To avoid an air lock in the cooling system, first disconnect the fluid supply hose to the throttle assembly, which is shown in the photo below:

And pouring antifreeze into the expansion tank, you need to pour it until it pours out of this disconnected hose. Then we put it on the output and tighten the clamp. Next, top up to the required level, and tighten the tank cap.

We start the engine and let it warm up until the radiator cooling fan works. We are waiting for the car to completely cool down (in the morning after replacement) and look at the fluid level in the expander.
