I have the greddy pulley kit on my car, and I don't know if I need a new water pump pulley. I can turn the pulley by hand with the belt and everything connected. Is this normal? Or is my pulley worn out? Thanks

 

Single turbo? Airpump removed?

If so, it's because of the removal of your air pump. There is now much less contact from the belt to the water pump. It's a common issue that has been remedied by the addition of an idler pulley...

FD Idler Pulley Kit

If you still have the airpump, than check your belt tension. The pulleys themselves will likely outlast mankind.

 

Twin turbos still and no airpump. I was looking at those pulley kits and should probably get one. Thanks for the reply

 

Also with the greddy pulley kit, if I bought the idler pulley kit what length of belt would I get?

 

Check out the parts drop down menu for the idler pulley:

Awesome thanks

 

No problem. The Pineapple idler is excellent quality. I just picked one up myself.

 

^This!

I did the same not too long ago, and the quality is excellent
