4.6. Removal and check of the thermostat on the car with the engine UEPA-331

Serviceability of the thermostat can be checked, without removing it. At the serviceable thermostat after launch of the cold engine the taking-away (lower) hose of a radiator has to remain some time cold, and then quickly to heat up, indicating the beginning of circulation of liquid on a big circle (see. "Description of a design"). If the taking-away hose of a radiator begins to heat up practically right after launch of the engine or does not heat up in general, it indicates malfunction of the thermostat and need of its replacement.

We merge cooling liquid (see. "Replacement of cooling liquid on the car with the engine UEPA-331").

The screw-driver we weaken the screw of a collar of fastening of a bypass hose to a thermostat branch pipe...

... also we remove a hose from a branch pipe.

Similarly we weaken the collar screw...

... also we remove the bringing hose of the pump of cooling liquid from a thermostat branch pipe.

Having raised the thermostat...

... we weaken the screw of a collar of fastening of the bringing hose (from a radiator) to a thermostat branch pipe...

... also we remove the thermostat.

For check of the thermostat we lower it in a vessel with cooling liquid, we warm up liquid and we control the beginning of opening of the main valve on the thermometer.

We install the thermostat in the return sequence.
