CAUSE | SOLUTION |
The coolant temperature is very high. At the same time the instrument cluster warning light |
| Insufficient cooling liquid in the cooling system | Check and, if necessary, bring to the coolant level. At constant coolant loss, determine and correct the cause of coolant leakage |
| Do not open the thermostat | Check whether the hot water hoses connected to the radiator. If the hoses are cold, remove the check operation and, if necessary, replace the thermostat. Alternatively, remove the thermostat. Thus the engine will warm up to normal operating temperature for a longer time |
| Dirty outer surface of the radiator | Blow the radiator with compressed air from the engine compartment |
| Reduced permeability of the radiator due to deposits on the inner surface of the heat sink of lime or rust | Replace radiator |
| Radiator fan is not working | On the fan power connections Check the electrical connections to the thermal sensor and fan motor. Check the engine cooling fan, which disconnect the electrical connector from the temperature sensor and lock the connector pins. Ignition radiator fan should work. Otherwise, replace the radiator fan motor |
| Faulty valve in the lid of the expansion tank | Check valve pressure |
| Faulty coolant temperature | Check the indicator and coolant temperature sensor |
| It does not work the water pump | Replace the water pump drive belt |
