Check of functioning of system of cooling

Many gross infringements in engine work are connected with malfunctions of system of cooling. If the car is equipped by automatic transmission its functioning and service life also directly are connected with work of system of cooling.

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


1. Slowly, being careful in case the engine has not absolutely cooled down yet, uncover a radiator. Carefully wash out it from within and outside of pure water. Also wash out a jellied mouth of a radiator. Presence of traces of corrosion in a jellied mouth means that it is necessary to replace a cooler. The cooler in a radiator should be rather pure and transparent. If it has brownish colour, drain system and fill in in it a new cooler.
2. Carefully check up 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 out if to compress a hose a hand. Will pay special attention on the collars keeping hoses on components of system of cooling. These collars can cut or pierce hoses that will lead to cooler leak.
3. Make sure of reliability of fastening of all шланговых connections. Cooler leaks are usually shown in the form of white or rusty colour of adjournment in the field of hermetic sealing infringement. If on your car collars of wire type it is possible are used, 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 condenser of the conditioner of air, there, where it is available). Remove all insects, leaves and the other extraneous subjects which have got on edges of a radiator. Be very cautious not to damage an edge and not to cut about them fingers.
5. If cooler level constantly falls, and you have not found out any leaks, it is necessary to make check by pressure of a cover of a radiator and all cooling system.
