4.11. DOHC engine thermostat

1–bolt, 15–20 N • m;
2–the sensor of temperature of cooling liquid;
4–thermostat casing;
7–the union of an exit of cooling liquid.


1. Merge cooling liquid to the level located below the thermostat.
2. Remove the union of an exit of cooling liquid and laying.
3. Remove the thermostat.
4. On a thread suspend the thermostat in a transparent vessel with water. Insert into water the thermometer, heat up a vessel with water and watch the thermostat valve. Define temperature of the beginning of opening and complete opening of the valve of the thermostat.

Temperature of the beginning of opening of the valve of the thermostat: 82°С.
Temperature of complete opening of the valve of the thermostat: 95 °C.
Thermostat valve stroke: 8,0 mm


1. Establish the thermostat so that the valve for air removal correctly settled down in a nest. If the thermostat is established in the wrong situation, its working capacity can be broken.
2. Establish new laying and the union of an exit of cooling liquid.
3. Fill in in cooling system necessary amount of demanded cooling liquid. Start up the engine and check absence of leaks from cooling system.
