17.23. Check of functioning of system of cooling

Annually or each 20 000 km of run

Many serious violations in operation of the engine are connected with malfunctions of system of cooling. If the car is equipped with automatic transmission, its functioning and service life also are directly connected with work of system of cooling.

Check of system of cooling should be made at the cold engine therefore it is better to be engaged in it before the first trip for the present day or not earlier than in three hours after engine switching off.

 PERFORMANCE ORDER

  1. Slowly, being careful in case the engine yet absolutely cooled down, uncover a radiator. Carefully wash out it from within and outside pure water. Also wash out a jellied mouth of a radiator. Existence of traces of corrosion in a jellied mouth means that it is necessary to replace a cooler (see. Section Plums, washing and filling of system of cooling). The cooler in a radiator should be rather pure and transparent. If it has brownish color, drain system and fill in in it a new cooler.
  1. Carefully check radiator hoses, and also hoses of a heater which have smaller diameter. Check hoses of system of cooling on all length, making replacement of any burst, blown-up or worn-out hose. Cracks are easier for finding if to compress a hose a hand. Pay special attention to the collars holding hoses on components of system of cooling. These collars can cut or pierce hoses that will lead to leakage of a cooler.
  1. Make sure of reliability of fastening of all shlangovy connections. Leakages of a cooler are usually shown in the form of white or rusty color of deposits in the field of sealing violation. If on your car collars of wire type are used, it is possible, there is a sense to replace them with collars of screw type.
  2. By means of the compressed air or a soft brush clear a forward part of a radiator (and also the condenser of the conditioner of air where it is available). Remove all insects, leaves and the other extraneous subjects which have got on edges of a radiator. Be very careful not to injure an edge and not to cut about them fingers.
  3. If cooler level constantly falls, and you did not find any leaks, it is necessary to make check by pressure of a cover of a radiator and all cooling system.
