GENERAL INFORMATION

REASON
ELIMINATION METHOD
Temperature of cooling liquid the very high. Thus on a combination of devices the control lamp burns
Insufficiently cooling liquid in cooling system Check and, if necessary, finish to norm level of cooling liquid. At continuous losses of cooling liquid define and eliminate the reason of an effluence of cooling liquid
The thermostat does not open Check, whether hoses of system the coolings connected to a radiator heat up. If hoses cold, remove, check working capacity and, if necessary, replace the thermostat. Alternatively, remove the thermostat. Thus the engine will get warm to normal working temperature longer time
The external surface of a radiator is polluted Blow a radiator the compressed air from a motor compartment
Passableness of a radiator at the expense of adjournment on an internal surface of a radiator of a limy raid or a rust is reduced Replace a radiator
The radiator fan does not work On the fan with an electric drive check reliability of connection of electric sockets to a temperature-sensitive element and the fan electric motor. Check serviceability of the engine of the fan of a radiator for what disconnect the electric socket from a temperature-sensitive element and close socket contacts. At the included ignition the fan of a radiator should work. Otherwise replace the electric motor of the fan of a radiator
The valve in a cover of a broad tank is faulty Check the valve under pressure
The index of temperature of cooling liquid is faulty Check serviceability of the index and the sensor of temperature of cooling liquid
The water pump does not work Replace a belt of a drive of the water pump
