Can you turn a water pump pulley by hand?
The only pulleys you should be able to turn by hand when the serpentine belt is not in place are: the water pump, alternator, and power steering pump pulleys. That you cannot rotate either cam or crankshaft pulleys by hand is completely normal. If you were able to rotate them bare handed, THEN you would have a problem.
Is water pump pulley supposed to spin freely?
New water pump should be nice a tight and not spin freely. Also the rotation should be perfectly smooth. If it feels gritty, it’s bad. Bearings, like the tensioner pulley are the same.
Should a water pump pulley have play?
The water pump pulley should not have much “play” in it at all. Any side to side movement would indicate wear in the shaft bushing and likely be a leak at some point in the near future. Idler pulley has a bearing in it that has a little play in it, but not much.
What causes a water pump pulley to spin?
There are multiple ways this metal component can be damaged, including having an incorrect sized or improperly adjusted water pump belt installed, vehicle accidents or problems with the internal bearings that allow the pulley to spin. This symptom is commonly recognized by oil service technicians…
What should the rotation of a water pump be?
New water pump should be nice a tight and not spin freely. Also the rotation should be perfectly smooth. If it feels gritty, it’s bad. Bearings, like the tensioner pulley are the same. A free spinning one is bad, and one that is smooth and tight is good. Judging from the video, yours is good. Another easy way to tell is if it leaks or not…

In order to reduce the potential of having your engine overheat or other major mechanical problems developing, having the water pump pulley replaced before it breaks completely is recommended by all mechanics and automotive manufacturers.
How are two pulleys used in a belt system?
Two pulleys can be used to create a simple belt and pulley system, in which a belt is looped between the two pulleys. One pulley is the “driving pulley”, and as it spins, it transmits power through the belt either via friction or teeth, thus spinning a “driven pulley”.
