Replacing the thermostat on the Niva with your own hands

Usually, if the thermostat malfunctions on the Niva, and indeed on all other cars, it is not repaired, but a complete replacement is made. This procedure itself is simple, but first it will be necessary to completely drain the coolant. Since the engines of the Niva and the “classics” are the same, you can read about draining the antifreeze here: replacing antifreeze with a VAZ 2107... After the coolant is drained from the engine and radiator, you can proceed further and here we only need one Phillips screwdriver or a holder with a bit of a suitable size:

It will be necessary to unscrew the fastening bolts of the clamps, which reliably connect the pipes and terminals of the Niva thermostat. In total, you will have to unscrew three bolts, which are clearly visible in the picture below:

After that, one by one, we disconnect the pipes from the thermostat taps, which is clearly shown in the photo below:

After that, we buy a new thermostat, the price of which for the Niva is about 300 rubles and we install it in the reverse order.

Also, it should be borne in mind that before putting on the pipes, they must be wiped dry, and if necessary, replace the clamps with new ones. If, after installation, it turns out that antifreeze or antifreeze oozes in some places of the connection, then the surest way would be to replace the required pipe with a new one!
