11.9. Characteristic malfunctions in the engine cooling system

GENERAL INFORMATION

REASON
WAY OF ELIMINATION
Engine overheat (according to the index of temperature)
Low level of cooling liquid Restore level.
Weakening of a belt of the fan Adjust a belt tension.
Perezhatiye of hoses Replace hoses.
There is no access of a stream of air to a radiator Clear a radiator or push aside obstacles (fog lights, etc.)
The radiator mouth stopper is faulty Replace a stopper.
Wrong installation of the moment of ignition Adjust.
Low turns of idling Adjust.
Formation of air traffic jams in the cooling system Remove air.
Severe conditions of the movement Periodically you transfer the engine to the mode of the raised idling turns to improve cooling.
Wrong installation of details of the cooling system Establish details.
The thermostat is faulty Replace.
Breakage of the roller of the pump or failure of a krylchatka Replace the pump.
Radiator contamination Wash out a radiator.
Contamination of channels of the cooling system Wash out system.
Deposits of a scum in the cooling channels Repair or replace the block of cylinders. The scum will be visible at removal of details of the cooling system or during removal of caps of channels.
Wheels completely do not rastormazhivatsya Repair brakes.
The increased friction in engine details Repair the engine.
Concentration of antifreeze exceeds 68% Restore normal composition of cooling liquid.
Violation of air consolidations Restore consolidations.
Malfunction of the sensor or index Repair or replace the faulty device.
Loss of cooling liquid owing to leak or foaming

Replace liquid, repair or replace faulty details.

The engine does not get warm up to the normal temperature
The thermostat is faulty Replace.
Malfunction of the sensor or index Repair or replace the faulty device.
Losses of cooling liquid (emission)
Level of liquid is higher than norm Restore level.
Engine stop right after driving Before a stop the engine has to work a little on bystry single to the course.
Education in the cooling system of air traffic jams (liquid "eruption" is sometimes observed) Remove air.
Insufficient concentration of antifreeze owing to what the boiling point goes down Restore normal composition of liquid.
Aging of antifreeze or pollution Replace liquid.
The leaks caused by weakening of collars of hoses, fasteners, drain traffic jams, malfunction of hoses or a radiator Execute pressure testing of system and find places of a leak, repair.
Damage of laying of a head of cylinders Replace laying.
Cracks in a head of cylinders, the soaking-up collector or in the block of cylinders Replace faulty details.
The radiator mouth stopper is faulty Replace a stopper.
Hit of cooling liquid in oil (the block of cylinders)
Damage of laying of a head of cylinders Replace laying.
Cracks in a head of cylinders, the soaking-up collector or in the block of cylinders Replace faulty details.
Level of liquid is not restored
Low level of liquid Add to the mark FULL.

Leak in the cooling system

Execute pressure testing of system and find places of a leak, repair.
The radiator stopper, damage or lack of laying is leaky closed Repair, replace laying.
The radiator stopper is faulty Replace.
The tube of a broad tank is littered or flows Eliminate defects.
Air vents of a broad tank are littered Clean.
Noise
Zadevany krylchatka of the fan for a casing Adjust the provision of a casing, check a condition of support of the engine.
Weakening of a krylchatka on a pump shaft Replace the pump.
It is worn-out (slips a drive belt) Replace or grease a belt with silicone lubricant.
Weakening of a belt of the fan Adjust a belt tension.
Pulley roughness Replace a pulley.
Wear of the bearing of the pump Take off a belt and be convinced that noise proceeds from the pump. Replace the pump.
The planes of pulleys are displaced (a belt distortion) Check combination of the planes of pulleys. If necessary repair.
Liquid does not come to a heater radiator
Deformation of an inlet branch pipe of the pump Eliminate.
Excess of hoses of a radiator of a heater Eliminate an excess or replace a hose.
Deformation of a branch pipe or channels of a radiator of a heater Repair or replace a radiator.
The final branch pipe of the thermostat is littered or pressed Remove a scum or eliminate perezhaty.
Contamination of a perepuskny opening of the soaking-up collector Clean.
The heater crane is faulty Replace the crane.
Contamination of the channel of cooling liquid in the soaking-up collector Clean or replace a collector. Right after a stop the engine passes into a condition of "a thermal otmokaniye". It is caused by temperature increase of cooling liquid on the idle hot engine, in the absence of circulation through a radiator. If temperature of the engine exceeds a boiling point, then liquid "transfusion" is observed. Rare manifestation of such effect is allowed.
