Engine Coolant Water Pump

Crankshaft belt camshaft coolant recirculates from the radiator to the engine and back to the radiator.

Engine coolant water pump. It is an impeller pump and is usually buried under the timing belt cover on the side of the engine. 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. A whining sometimes a grinding noise coming from the front of your engine. Also a stuck thermostat or clogged radiator will cause your engine to overheat.

The inlet to the pump is located near the center so that fluid returning from the radiator hits the pump vanes. But the water pump glossy green leak will usually show up on the floor right under the water pump. Your vehicle s engine is working extremely hard and in turn generating lots of heat. Water pump failure can stem from the condition and amount of coolant in your vehicle s cooling system.

A bad hose gasket or radiator may also leak coolant. Engine coolant is directed by the thermostat to the inlet of the circulating pump and is returned directly to the engine bypassing the radiator. Although the water pumps in. Operation the water pump also called a coolant pump is driven by one of two methods.

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. It is pumped into the warm engine block where it picks up some heat. To prevent it from overheating the water pump circulates coolant throughout the engine and cooling system to remove heat from critical engine parts. The pump is operated by the engine s drive belt as the belt turns the pump turns.
