Engine Coolant Water Pump

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.

Engine coolant water pump.

The pump is operated by the engine s drive belt as the belt turns the pump turns. Also a stuck thermostat or clogged radiator will cause your engine to overheat. Engine coolant is directed by the thermostat to the inlet of the circulating pump and is returned directly to the engine bypassing the radiator. 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.

The inlet to the pump is located near the center so that fluid returning from the radiator hits the pump vanes. It is pumped into the warm engine block where it picks up some heat. Crankshaft belt camshaft coolant recirculates from the radiator to the engine and back to the radiator. Although the water pumps in.

It is an impeller pump and is usually buried under the timing belt cover on the side of the engine. A bad hose gasket or radiator may also leak coolant. The pump vanes fling the fluid to the outside of the pump where it can enter the engine. Low temperature coolant leaves the radiator by the bottom outlet.

The water pump uses centrifugal force to send fluid to the outside while it spins causing fluid to be drawn from the center continuously. Water pump failure can stem from the condition and amount of coolant in your vehicle s cooling system. To prevent it from overheating the water pump circulates coolant throughout the engine and cooling system to remove heat from critical engine parts. But the water pump glossy green leak will usually show up on the floor right under the water pump.
