the engine to run at higher temperatures resulting in higher engine efficiency. The pressure cap fits onto the
filler neck portion above the radiator tank. If the pressure increases by 15 PSI, the boiling point temperature
increases by 113°C.

6 Cooling fan: The cooling fan or water fan is fitted on the water pump pulley. It has four or five blades. It sucks
the air from the radiator core, due to which the tube gets cooled and the tube cools the water and this air keeps
falling on the engine, due to which the engine keeps getting cooled.

Radiator, pressure cap, types of hoses.
Radiator: The device that absorbs the heat of water and cools it is called “Radiator” or “Water Heat Condenser”.
A radiator is a type of water tank to supply water to the engine. This process helps to prevent the engine from
overheating.
It works by transferring heat from hot water or steam to the surrounding air, warming the space. The radiator is
fitted in front of the engine.
