The water pump pulley is supposed to spin freely. The Pulley is attached by a shaft to an impeller that is located in the engine blocks cooling passages. When the pulley is rotated the impeller circulates coolant in the engine and pumps coolant out into the radiator to be cooled.
If the pulley won't rotate freely the water pump needs to be replaced.
ok is replacing a water pump easy? and how much will it cost?
Origianl GM water pump and coolant is approx $150 (aftermarket water pump approx $70) and job takes about 1 to 1.2 hours to replace pump.
Yes its suppose to spin freely. You need to loosen the bolts while the serp belt is on. The Serp belt helps hold the pully in place.
