What is the water pump for?
The water pump’s main purpose is to regulate the temperature in the engine. The waterpump
is part of the cooling system of the car like the radiator
or the thermostat.
In general the engine water pump
is a centrifugal pump operated by the timing belt
. The latter helps to distribute of cooling liquid throughout the engine. The cooling fluid in the engine exits the water pump
and flows through the engine block and the cylinder head. It then continues through the radiator before it flows back to the water pump.
