11.9. Characteristic malfunctions in system of cooling of the engine
THE GENERAL DATA

THE REASON
WAY OF ELIMINATION
Engine overheat (under the temperature index)
Low level of a cooling liquid Restore level.
Easing of a belt of the fan Adjust a belt tension.
Пережатие hoses Replace hoses.
There is no access of a stream of air to a radiator Clear a radiator or push aside obstacles (antifog headlights, etc.)
The stopper of a mouth of a radiator is faulty Replace a stopper.
Wrong installation of the moment of ignition Adjust.
Low turns of idling Adjust.
Formation of air stoppers in cooling system Remove air.
Movement severe conditions Periodically translate the engine in a mode of the raised turns of idling to improve cooling.
Wrong installation of details of system of cooling Establish details.
The thermostat is faulty Replace.
Breakage of the platen of the pump or failure крыльчатки Replace the pump.
Radiator contamination Wash out a radiator.
Contamination of channels of system of cooling Wash out system.
Scum adjournment in cooling channels Repair or replace the block of cylinders. The scum will be visible at removal of details of system of cooling or at removal заглушек channels.
Wheels completely not растормаживаются Repair brakes.
The raised friction in engine details Repair the engine.
Concentration of antifreeze exceeds 68 % Restore normal structure of a cooling liquid.
Infringement of air consolidations Restore consolidations.
Malfunction of the gauge or the index Repair or replace the faulty device.
Loss of a cooling liquid owing to leak or foaming

Replace a liquid, repair or replace faulty details.

The engine does not get warm to normal temperature
The thermostat is faulty Replace.
Malfunction of the gauge or the index Repair or replace the faulty device.
Losses of a cooling liquid (emission)
Level of a liquid above norm Restore level.
Engine stop right after drivings Before a stop the engine should work a little on fast single to a course.
Formation in system of cooling of air stoppers (liquid "eruption" is sometimes observed) Remove air.
Insufficient concentration of antifreeze owing to what the boiling point goes down Restore normal structure of a liquid.
Ageing of antifreeze or pollution Replace a liquid.
The leaks caused by easing of collars of hoses, fixing elements, drain stoppers, malfunction of hoses or a radiator Execute опрессовку systems and find leak places, repair.
Damage of a lining of a head of cylinders Replace a lining.
Cracks in a head of the cylinders, a soaking up collector or in the block of cylinders Replace faulty details.
The stopper of a mouth of a radiator is faulty Replace a stopper.
Hit of a cooling liquid in oil (the block of cylinders)
Damage of a lining of a head of cylinders Replace a lining.
Cracks in a head of the cylinders, a soaking up collector or in the block of cylinders Replace faulty details.
Liquid level is not restored
Low level of a liquid Add to mark FULL.

Leak in cooling system

Execute опрессовку systems and find leak places, repair.
The radiator stopper, damage or absence of a lining is leaky closed Repair, a lining replace.
The radiator stopper is faulty Replace.
The tube of a broad tank is littered or flows Eliminate defects.
Ventilating apertures of a broad tank are littered Clean.
Noise
Задевание крыльчатки the fan for a casing Adjust casing position, check up a condition of support of the engine.
Easing крыльчатки on a pump shaft Replace the pump.
It is worn out (slips a drive belt) Replace or grease a belt with silicone greasing.
Easing of a belt of the fan Adjust a belt tension.
Pulley roughness Replace a pulley.
Deterioration of the bearing of the pump Remove a belt and be convinced that noise proceeds from the pump. Replace the pump.
Planes of pulleys are displaced (a belt warp) Check up combination of planes of pulleys. If necessary repair.
In a radiator of a heater the liquid does not arrive
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 пережатие.
Contamination перепускного apertures of a soaking up collector Clean.
The heater crane is faulty Replace the crane.
Contamination of the channel of a cooling liquid in a soaking up collector Clean or replace a collector. Right after the engine passes stops in a condition "thermal отмокания". It is caused by rise in temperature of a cooling liquid on the idle hot engine, in the absence of circulation through a radiator. If the engine temperature exceeds a boiling point liquid "transfusion" is observed. Rare display of such effect is supposed.
