Cooling system

Overheat

1. Insufficient refrigerant in the system (Head of Adjustment and routine maintenance).
2. Worn or damaged water pump drive belt is broken or adjustment of its tension (Head of Adjustment and routine maintenance).
3. Blocked internal channels of a radiator or contaminated (blocked) grille (Head of System of cooling, heating and air conditioning).
4. Faulty thermostat (Head of System of cooling, heating and air conditioning).
5. Broken or cracked fan blades (Head of System of cooling, heating and air conditioning).
6. Do not keep the pressure radiator cap. Inspect the pressure cap (refer to the service station).

Hypothermia

1. Faulty thermostat (Head of System of cooling, heating and air conditioning).
2. Inaccurate temperature meter (Head System of an onboard electric equipment).

External coolant leak

1. Damaged or destroyed as a result of the aging of the material, or hoses are loose on their unions. Replace the hoses and / or tighten collars of their fastening (Head of Adjustment and routine maintenance).
2. Spoiled water pump seals. In this case, the cooler will trickle through the inspection hole in the pump housing (Chapter cooling systems, heating and air conditioning).
3. There have been leaks of internal channels of a radiator or the side of the tank (s). Requires professional repair the radiator (see the description of the procedure for the withdrawal. Chapter cooling systems, heating and air conditioning).
4. There have been leaking through the drain plug of the engine (Chapter Settings and maintenance) or the clutch release cork water galleries (head straight six-cylinder engine).

Internal coolant leaks

Internal coolant leaks are usually detected by checking the state of the motor oil. Inspect the blade of the probe and the inner surface of the cover (covers) of cylinders on presence of traces of water and foaming oil.

1. Have the leak through the cylinder head gasket. Inspect the cooling system pressure.
2. There are cracks on the cylinder walls or in the casting head. To check disassemble the engine (head straight six-cylinder engine).

Is a loss of coolant

1. system fueled too much cooler (Head of Adjustment and routine maintenance).
2. The cooler boils due to overheating of the engine (see. Section holds surface ignition (the engine continues to run after the ignition is switched off)).
3. There have been internal or external coolant leaks (see. Categories External coolant leakage and internal leakage of the coolant).
4. Defective radiator cap. Check the pressure cap.

Disturbed circulation cooler

1. Do not functioning properly the water pump. The easiest way to ensure the functioning of the pump pinching the upper radiator hose when running the engine at idle. If the hose is released, there is a push liquid inside the pump is functioning properly (Chapter Settings and maintenance).
2. Broken patency of the cooling system. Drain the coolant, flush the system and fill it with fresh mixture (Head of Adjustment and routine maintenance). If the need arises, remove a radiator (Head of System of cooling, heating and air conditioning) and spend it obratnopotochnuyu washing.
3. Worn or damaged water pump drive belt is broken or adjustment of its tension (Head of Adjustment and routine maintenance).
4. Conjuring thermostat (Head of System of cooling, heating and air conditioning).
5. On 6-cylinder engines can take place properly install the drive belt that rotates the pump in the reverse direction (Head of Adjustment and routine maintenance).
