CAUSE | REMEDY |
Too high coolant temperature indicator is in the red area of the scale |
| Too little coolant circuit | The compensation tank should be filled up to the mark. See subsection 5.2., Check the tightness of the cooling system. |
| Do not open coolant regulator (thermostat) | Check whether the upper hose heated coolant to the radiator. If not, remove and check the controller, replace if necessary. |
| Faulty pump liquid cooling system | Disassemble and check the pump. |
| Faulty sensor indication of the coolant temperature | Additionally, check the sensor. |
| Faulty coolant temperature display | Check the display device. |
| Defective radiator cap screw | Check the cooling system, perform pressure test screw cap. |
| Plastnki dirty radiator | Remove the heat sink and blow compressed air from the engine. |
| Radiator intoxicated within calcareous sediments and corrosion products. Radiator heated only at the top, does not heat the lower radiator hose Coolant | Replace the heat sink. |
| The radiator fan rotates in accordance with an increase in engine speed, faulty bimetallic plate hydraulic clutch cooling fan | When the coolant temperature is about 90-95 ?� C, leave the engine running with the engine speed 4000-4500 r / min., And the speed of the fan shaft should clearly increase. Otherwise, check the hydraulic clutch cooling fan, if necessary, replace the bimetallic platinku. |
