4.3. The thermostat

Arrangement of a cover of the thermostat in 4-cylinder models

The thermostat cover in 4-cylinder models is located behind the water pump.

Arrangement of a casing of the thermostat in 6-cylinder models

The thermostat casing (it is specified by an arrow) is located behind an inlet collector over a transmission.

The general check

1. Measure level of a cooling liquid, check up a tension drive a belt and functioning of the temperature gauge.
2. If the engine is warmed up too long, most likely, that has jammed the thermostat in open position. Replace the thermostat.
3. If the engine overheats, check up temperature of the top hose of a radiator if the hose not hot, means, the thermostat has jammed in the closed position. Replace the thermostat.

Thermostat check

1. For carrying out of more careful check the thermostat is necessary for removing from the engine.
2. If the thermostat is not closed at a room temperature, means, it is faulty and is subject to replacement.
3. Lower the thermostat in capacity with cold water (the thermostat is closed).
4. Warm up water in capacity and watch its temperature. The thermostat should not concern walls and a capacity bottom.
5. Write down thermometer indications when the thermostat only starts to open and when it is completely open. Compare the received sizes to technical requirements.
6. Replace the thermostat if it does not open or it is not closed or it gets jammed in any position.


1. Disconnect a wire of the minus plug of the accumulator.
2. Merge cooling liquid from a radiator. Disconnect a hose of a radiator from a casing of the thermostat or from an inlet tube.
3. In 4-htsilindrovyh engines disconnect an inlet tube from a thermostat casing. For the best access remove the oil filter.
4. In 6-cylinder engines a cover of the air valve also unscrew nuts (are specified by arrows) in a back part of the engine. Shift wires to get access to bolts of a cover of the thermostat.
5. Disconnect an inlet tube (it is specified by an arrow) from a head of cylinders and disconnect a tube from a thermostat casing (6-cylinder models).
6. Disconnect from a casing of the thermostat of fastening and a wire and remove a casing.
7. Get the thermostat from a casing.
8. Clean joined surfaces and establish a new lining.
9. Establish the thermostat and a thermostat casing upside-down removals.
