General check
| PERFORMANCE ORDER |
| 1. Measure level of cooling liquid, check a tension of a driving belt and functioning of the temperature sensor. |
| 2. If the engine is warmed up too long, most likely, that jammed the thermostat in open situation. Replace the thermostat. |
| 3. If the engine overheats, check temperature of the top hose of a radiator if the hose not hot, means, the thermostat jammed in a closed position. Replace the thermostat. |
|
Thermostat check
| PERFORMANCE ORDER |
| 1. For carrying out more careful check the thermostat is necessary for removing from the engine. |
| 2. If the thermostat is not closed at 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 situation. |
|
Replacement
| PERFORMANCE ORDER |
| 1. Disconnect a wire of the minus plug of the accumulator. |
| 2. Merge cooling liquid from a radiator. Disconnect a radiator hose from a casing of the thermostat or from an inlet tube. |
| 3. In 4-хцилиндровых 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 shooters) 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 being joined surfaces and establish new laying.
|
| 9. Establish the thermostat and a thermostat casing upside-down removals. |
