So I had a terrible belt squeel the other day when I started up the Mustang, I decided it was time to change the belt anyhow cause my pullies were slightly out of Alignment. When I looked behind the blower I found the reason the belt was squeeling. The vortech Shaft seal was leaking oil really bad. 350+ dollars to send it back to vortech OR order a seal from Napa and replaced it myself? Of course I replaced it myself, and it was very easy Just remove the bolts on the back of the blower cover then lift the housing off, Tap the seal out of the back cover, then install a new seal. Reinstall in reverse, just be careful not to pinch the big O ring. have you ever wondered what it looks like inside a T trim? well here you go. the 8 rib kit vortech sends is a pretty good kit, But the spacers were just to big for my pullies to all line up properly, so After buying a laser level, I ended up using washers to get mine lined up real good tonight. just a few things to put on tomorrow and she will be back up and running without all the squeeling.
