Engine Coolant Water Pump

It is pumped into the warm engine block where it picks up some heat.

Engine coolant water pump.

It is an impeller pump and is usually buried under the timing belt cover on the side of the engine. Water pump failure can stem from the condition and amount of coolant in your vehicle s cooling system. Your vehicle s engine is working extremely hard and in turn generating lots of heat. Although the water pumps in.

Crankshaft belt camshaft coolant recirculates from the radiator to the engine and back to the radiator. Also a stuck thermostat or clogged radiator will cause your engine to overheat. Low temperature coolant leaves the radiator by the bottom outlet. A whining sometimes a grinding noise coming from the front of your engine.

Operation the water pump also called a coolant pump is driven by one of two methods. The pump is operated by the engine s drive belt as the belt turns the pump turns. Directing water to circulate only through the engine allows the engine to reach optimum operating temperature as quickly as possible whilst avoiding localised hot spots. A bad hose gasket or radiator may also leak coolant.

The water pump uses centrifugal force to send fluid to the outside while it spins causing fluid to be drawn from the center continuously. The inlet to the pump is located near the center so that fluid returning from the radiator hits the pump vanes. Engine coolant is directed by the thermostat to the inlet of the circulating pump and is returned directly to the engine bypassing the radiator. Blades on the pump force coolant to flow through the engine and back to the radiator to be cooled by a forced air cooling fan.
