Remove strut crossbar by removing the 4nuts that hold it into place, set side
(If equipped if not skip to step:3)

You may be able to get away with taking the lower bolt of the alt off and just leaving it bolted to the tentioner but will make things harder toine up when you put it back together

Guys i need some help. On my tensioner where the heater hose is connected the bolt for the fitting sheared off. Im drilling it out but i need to know what size the bolt is or what size i can use for the hole. My dad said to try running it without a bolt but I dont trust leaving it open like that. Im not sire if i can get it from my work even tho i work for GM so i need to know what size it is just in case

Also the other bolt didnt break but when i tightened it down the bolt stopped but i could still move the hose up and down with plenty of room. Why is that? Is that normal?

Great write up Justin. Just found out the SS, old TAZ63, is leaking at the plastic 90deg elbow. Your instructions will help assure I don't remove too much stuff.
