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.
