Cooling system

Overheat

  1. The cooler in system does not suffice (The head Nastroyki and routine maintenance).
  2. The driving belt of the water pump is worn-out or damaged or adjustment of its tension is broken (The head Nastroyki and routine maintenance).
  3. Internal channels of a radiator are blocked or it is polluted the front grille (The head of the Cooling system, heating and air conditioning) (is blocked).
  4. The thermostat (The head of the Cooling system, heating and air conditioning) is faulty.
  5. Fan blades (The head of the Cooling system, heating and air conditioning) are broken or burst.
  6. Does not hold pressure a radiator cover. Make check of a cover pressure (address on car repair shop).

Overcooling

  1. The thermostat (The head of the Cooling system, heating and air conditioning) is faulty.
  2. Indications of the measuring instrument of temperature (The head Sistema of onboard electric equipment) are inexact.

External leakages of a cooler

  1. Hoses are damaged or destroyed as a result of material aging or their fastening on unions weakened. Replace hoses and/or tighten collars of their fastening (The head Nastroyki and routine maintenance).
  2. It is spoiled epiploons of the water pump. In this case the cooler will exude through a control opening in a pump housing (The head of the Cooling system, heating and air conditioning).
  3. Leaks from internal channels of a radiator or the side tank(s) take place. Professional repair of a radiator is required (the description of the procedure of removal see in the Head of the Cooling system, heating and air conditioning).
  4. Leaks through a drain stopper of the engine (The head Nastroyki and routine maintenance) or release traffic jams of water galleries take place (The head the Line six-cylinder engine).

Internal leakages of a cooler

Internal leakages of a cooler usually come to light by check of a condition of motive oil. Examine an edge of the measuring probe and internal surfaces of a cover (covers) of cylinders on existence of traces of water and foaming of oil.

  1. Leaks through laying of a head of cylinders take place. Make check of the cooling system pressure.
  2. There are cracks on walls of cylinders or in casting of a head. For check disassemble the engine (The head the Line six-cylinder engine).

There are losses of a cooler

  1. system too much cooler is filled (The head Nastroyki and routine maintenance).
  2. The cooler boils away as a result of an engine overheat (see the Section kalilny ignition Takes place (the engine continues to work after switching off of ignition)).
  3. Internal or external leakages of a cooler take place (see Sections External leakages of a cooler and Internal leakages of a cooler).
  4. The radiator cover is faulty. Check a cover pressure.

Circulation of a cooler is broken

  1. The water pump does not function properly. It is the simplest to make sure of functioning of the pump having pressed the top hose of a radiator at the engine working at single turns. If at an otpuskaniye of a hose the liquid push in it is felt, the pump functions regularly (The head Nastroyki and routine maintenance).
  2. Passability of the cooling system is broken. Merge a cooler, wash out system and fill it with fresh mix (The head Nastroyki and routine maintenance). If there is such need, remove a radiator (The head of the Cooling system, heating and air conditioning) and carry out its obratnopotochny washing.
  3. The driving belt of the water pump is worn-out or damaged or adjustment of its tension is broken (The head Nastroyki and routine maintenance).
  4. The thermostat (The head of the Cooling system, heating and air conditioning) is jammed.
  5. On 6-cylinder engines the wrong laying of a driving belt can take place that leads to rotation of the pump in the opposite direction (The head Nastroyki and routine maintenance).
