Coolant thermostat (thermostat)
A warning  If the engine is hot after driving a small section of the route, it may be due to the fact that the radiator zashlakovyvaetsya calcareous sediments.
With increasing warming of the engine thermostat opens the large coolant circuit. If the coolant thermostat is closed due to a malfunction, the engine gets too hot. This can be identified by indication of the coolant temperature, which is in the red range, while simultaneously radiator remains cold. But a faulty thermostat, even after cooling, the coolant can be further opened. This is evident by the fact that the engine is no longer reaches its operating temperature, or an arrow indicating the engine coolant temperature slowly moves up than before winter or decreases power consumed for heating.
Check
| PERFORMANCE ORDER | | 1. Remove the control thermostat coolant. | | 2. Measure the height of the thermostat, note the size of "a". |  | 3. Slowly heat the thermostat in a water bath. Thus it should not come into contact with the walls of the vessel, and is completely immersed in water. The temperature is controlled suitable thermometer. At a temperature of about 87 ?� C bimetal regulator begins to lengthen, reaching a maximum elongation at a temperature of about 102 ?� C. Once the water reaches a temperature of bath opening, should start to open the butterfly valve of the thermostat. | | 4. Heat the water in the bath to boil it. Remove the thermostat, measure the height (dimension "b") and compare with the first measured value (the size of "a"). At the end of the opening lift amount of opening is about 8 mm. Since this temperature is not reached, check whether the regulator opened up a comparable size, otherwise replace it. | | 5. Finally, make sure you fully closed again when cooled regulator, otherwise replace the regulator. | | 6. When not functioning, replace the thermostat. | | 7. Set the thermostat in place. |
