Check of functioning of the cooling system

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

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

 CHECK

1. Slowly, being careful in case the engine yet not absolutely cooled down, uncover a radiator. Carefully wash out it clear water from within and outside. Also wash out a jellied mouth of a radiator. Existence of traces of corrosion in a jellied mouth means that the cooler should be replaced. The cooler in a radiator has to be rather pure and transparent. If it has brownish color, drain system and fill in in it a new cooler.
2. Carefully check radiator hoses, and also heater hoses which have smaller diameter. Check cooling system hoses on all length, making replacement of any burst, blown up or worn-out hose. It is easier to find cracks if to squeeze a hose a hand. Pay special attention to the collars holding hoses on cooling system components. These collars can cut or pierce hoses that will lead to leakage of a cooler.
3. Make sure of reliability of fastening of all hose 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, then it is possible, there is a sense to replace them with collars of screw type.
4. By means of compressed air or a soft brush clear a forward part of a radiator (and also the air conditioner condenser where it is available). Remove all insects, the leaves and other foreign objects which got on radiator edges. Be very careful not to injure an edge and not to cut about them fingers.
5. 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.
