I was getting all kinds of noises from the engine. replaced the belt, tensioner, and idler pulley and half the squealing was gone. I was still getting more squeal and this continuous on and off scraping noise. Narrowed it down to my water pump and crank pulley. I was a little hesitant on the ASP underdrive pulley (to replace the crank pulley)...But man i love that thing! No issues with radio or lights. BUT...i highly recommend anyone who's thinking about this mod to do it yourself. I got lazy and paid Sears to do it and they managed to torque it down wrong (they didnt even think the part would work). My car threw a code for a misfire in cylinder 1... Just loosened the bolt and torqued it down correctly and no more problems. And the Squealing is gone. All i got left is that water pump for the scraping noise. But man that underdrive pulley rocks! I definitely recommend it! I dont think it works with S/C applications though.

 

Where did you get it? I've been looking for a v6 UDP

I used coupon code STANGMODS for 5% off. Awesome price since its a combo and free shipping. other sites i found were charging 300 just for the pulley =/

 

Awesome thanks a bunch for sharing, that'll be my next mod lol

 

No problem. Hope it works out well for you
