'96 Sedan Deville New Serpentine Belt!!!

Hi guys! I have friend who needs help installing new serpentine. I dont know much about caddies, I have read all related threads on this subject but am not quite sure where tension pully is at? Can anyone guide me on installing new serpentine belt??? I really appreciate anyones help or advice!! thanks!

Follow the diagram under the hood for routing. The tensioner should have a 1/2 inch square cut into it. Use a 1/2 inch breaker bar or socket wrench to turn the tensioner enough to get the belt on.

ok. awesome, thats what ive just read. so i need to look for a 1/2" square socket and use leverage to loosen it and then put new belt on according to diagram and then tightn 1/2"?? thanks man

The tensioner automatically tightens the belt. The socket wrench is to move the tensioner to get the belt on. You don't tighten anything!

ok, so all im doin is adjusting tensioner to be able to slip a belt on, and then move tensioner to tighten belt and then tighten bolt, right?? I appreciate ur answer.

The Tensioner is spring loaded. So you stick the 1/2" drive ratchet or breaker bar into the 1/2" square hole on the side of the tensioner, then pull it, hold it there while you release the belt from 1 or 2 pulleys. Then you can release the tensioner (it will spring back into position). Reverse the process for the install. Good luck, its kinda tight in there and a little tough to route it.
