Ok I ordered a set of Steeda underdrives online and the water pump pulley didnt sit far enough for the belt to ride on it. So does this mean I have the wrong sizes on all the pullies or can I install the crank and alt pulley?
Did you order the right year? Steeda has different pullies for the 99-04 and I think it splits at 99-01 and 02-04. I could be wrong but just look at thier website to confirm the years.
As far as leaving the WP pullie, yeah you can do that as long as the belt is tight, which is should be, just double check it. I've heard of people leaving the alt pulley stock and changing the rest. I changed all three and didn't notice a difference besides possibly reving faster.
Double check what your ordered and if it was the right year for your car.
Heres thet thing I ordered them on ebay and dont have the part number. The crank is engraved with a number Im looking into it but the Alt. pulley fits, but its bigger around than the stock one.Not sure what thats about? Was your Alt pulley like that? If the crank fits then Ill put it in and the Alt pulley and find a water pump pulley later. I know the crank is the biggest heaviest pulley of them all.
I bought a set of pulleys and I need to know the diffeerence between early 01 and late 01 pulleys. In a previous thread I described how the W.P. pulley I have now doesnt fit properly. Is this the only difference between the years. Will the crank and Alt pulley's be the same? 2002 GT
Some.....but nothing you'll really feel SOTP. As it is, 4.6L cars don't respond as well to an under drive pulley swap as the old 5.0L cars. But every little bit helps. Keep in mind though, if you don't swap ther waterpump pulley, you're going to need to buy a new serpentine belt along with it.
Infact here it is http://www.rpmoutlet.com/musv8mbp.htm and check out the motoblue WP pulley for $50. That should do it. Or maybe you can go through Steeda and they may be able to hook you up with just the WP pulley.
