Cooling system

Overheat

  1. The cooler in system (the Head of Adjustment and routine maintenance) does not suffice.
  2. It is worn out or damaged приводной a belt of the water pump or adjustment of its tension (the Head of Adjustment and routine maintenance) is broken.
  3. Internal channels of a radiator are blocked or is polluted the radiator lattice (the Head of System of cooling, heating and an air conditioning) (is blocked).
  4. The thermostat (the Head of System of cooling, heating and an air conditioning) is faulty.
  5. Are broken or треснуты fan blades (the Head of System of cooling, heating and an air conditioning).
  6. Does not hold pressure a radiator cover. Make check of a cover by pressure (address on a car repair shop).

Overcooling

  1. The thermostat (the Head of System of cooling, heating and an air conditioning) is faulty.
  2. Indications of a measuring instrument of temperature (the Head System of an onboard electric equipment) are inexact.

External leaks of a cooler

  1. Hoses or ослабло their fastening on unions are damaged or destroyed as a result of ageing of a material. Replace hoses and-or tighten collars of their fastening (the Head of Adjustment and routine maintenance).
  2. It is spoilt epiploons of the water pump. In this case the cooler will exude through a control aperture in the pump case (the Head of System of cooling, heating and an air conditioning).
  3. Leaks from internal channels of a radiator or the lateral tank (ов) take place. Professional repair of a radiator (the description of procedure of removal see in the Head of System of cooling, heating and an air conditioning) Is required.
  4. Leaks through a drain stopper of the engine (the Head of Adjustment and routine maintenance) or выжимные stoppers of water galleries (Head Rjadnyj the six-cylinder engine) take place.

Internal leaks of a cooler

Internal leaks of a cooler usually come to light by check of a condition of impellent oil. Examine an edge measuring probeа and internal surfaces of a cover (covers) of cylinders on presence of traces of water and oil foaming.

  1. Leaks through a lining of a head of cylinders take place. Make check of system of cooling by pressure.
  2. There are cracks on walls of cylinders or in head moulding. For check disassemble the engine (Head Rjadnyj the six-cylinder engine).

There are cooler losses

  1. System it is filled too much cooler (the Head of Adjustment and routine maintenance).
  2. The cooler boils away as a result of an engine overheat (the Section see Takes place калильное ignition (the engine continues to work after ignition deenergizing)).
  3. Internal or external leaks of a cooler (Sections External leaks of a cooler and Internal leaks of a cooler see) take place.
  4. The radiator cover is faulty. Check up a cover pressure.

Cooler circulation is broken

  1. The water pump does not function properly. Most easier to make sure of pump functioning having pressed the top hose of a radiator at the engine working on single turns. If at release a hose the push of a liquid in it is felt, the pump functions regularly (the Head of Adjustment and routine maintenance).
  2. Passableness of system of cooling is broken. Merge a cooler, wash out system and fill with its fresh mix (the Head of Adjustment and routine maintenance). If there is such necessity, remove a radiator (the Head of System of cooling, heating and an air conditioning) and spend it обратнопоточную washing.
  3. It is worn out or damaged приводной a belt of the water pump or adjustment of its tension (the Head of Adjustment and routine maintenance) is broken.
  4. The thermostat (the Head of System of cooling, heating and an air conditioning) is jammed.
  5. On 6-cylinder engines the wrong lining drive a belt that leads to pump rotation in the opposite direction (the Head of Adjustment and routine maintenance) can take place.
