ABSTRACT

The cooling system in a vehicle engine is a system that functions to maintain the
temperature of the mesi in ideal conditions.the engine in combustion in the
combustion process carries out the combustion process to produce energy and
with the engine mechanism is converted into motion power. The cooling principle
releases engine heat into the air, the type directly released into the air is called air
conditioning (water coouning) intermediate burner type called coolant

The cooling water cycle starts from the radiator then the water is pressed by the
water pump and driven by the crankshaft through the V-belt. Some types of cooling
systems:

-water cooling system (natural), this type utilizes waterholes to absorb heat in the
engine. This type is commonly found in small machines such as machine water
pumps

-The air conditioning system, as in this type of motor uses a stream of air passing
through the engine to transfer heat. Jeni aini is more suitable for use in open
engines such as motor engines

-The radiator cooling system uses the help of a radiator to move the engine heat.
This type is used on all types of cars that have a closed engine
