PERFORMANCE ORDER
1. If after start the engine gets warm very slowly, then, perhaps, the thermostat is in constantly open situation, and it needs to be replaced.
2. If the engine overheats, then a hand check a temperata ру the top hose of a radiator. If the hose cold, then, perhaps, the thermostat is in a closed position and does not pass cooling liquid to a radiator. In this case the thermostat is also subject to replacement.

4. For check of the thermostat lower it on a twine in a container with water. Gradually heating water, notice temperature at which the thermostat begins to open and completely will open. Take the thermostat from water and check that it was completely closed after cooling. Replace the thermostat if its parameters differ from technical requirements.
