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.  |
