Engine Coolant Water Pump

A whining sometimes a grinding noise coming from the front of your engine.

Engine coolant water pump. Low temperature coolant leaves the radiator by the bottom outlet. It is pumped into the warm engine block where it picks up some heat. The water pump uses centrifugal force to send fluid to the outside while it spins causing fluid to be drawn from the center continuously. It is an impeller pump and is usually buried under the timing belt cover on the side of the engine.

To prevent it from overheating the water pump circulates coolant throughout the engine and cooling system to remove heat from critical engine parts. 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. Although the water pumps in. 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.

Also a stuck thermostat or clogged radiator will cause your engine to overheat. The pump vanes fling the fluid to the outside of the pump where it can enter the engine. Your vehicle s engine is working extremely hard and in turn generating lots of heat. But the water pump glossy green leak will usually show up on the floor right under the water pump.

A bad hose gasket or radiator may also leak coolant. Water pump failure can stem from the condition and amount of coolant in your vehicle s cooling system. 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.
