Water Pump: Description and Operation
GENERAL INFORMATION
A centrifugal water pump circulates coolant through the water jackets, passages, intake manifold, radiator core, cooling system hoses and heater core.
The pump is driven from the engine crankshaft by a drive belt.
The water pump impeller is pressed onto the rear of a shaft that rotates in a bearing pressed into the water pump body. The body has a small hole for
ventilation. The water pump seals are lubricated by antifreeze in the coolant mixture. Additional lubrication is not necessary.
