Iam doing the 3.0 pully swap...and i can no get the damn belt on at all. tried it for 4 hours last night. is the tensioner the lil shock absorber looking thing or is it somewhere else. and what the hell do i have to do to it...i tried to press it down with my hands a it did not move at all. can you help me at all?

 

Knightrider22... The tensioner has a square 3/8 hole in bracket. Place a 3/8 drive breaker bar or rachett end into it. Use that for leverage, the tensioner assembly should then move easily.

 

i did that mod earlier this week, what you need to do is wrap a screwdriver with a towel then place screwdriver on the top of the tensioner and push down, make sure you have the end of ur screwdriver under the black bracket behind the tenisoner. once you get that push down and hold then with ur other hand take belt off the supercharger pulley, if you are gonna swap DO NOT use the 3 jaw puller, speaking from exp. i fucked up my old pulley.

also if you cant get the stock pulley off, or used a 3 jaw and found out it will **** up ur pulley its best to take the super chager off to get the belt back on (u do this by putting the belt on the pulley then drawing down the opposite side with your screws), with someone holding down the tensioner.......if not you'll be fighting it and get pissed like i did.

if this doesnt make sense let em know and ill send u pictures

 

You need a 15mm open end wrench. right behind the pulley the is a square raise nipple right next to the engine lift eyelet. put the wrench on there and push to the back of the car. i push down on the pulley to help it along becuase it does suck another wonderful gm design. that is how i do mine and did wheni put the 3.1 pulley on
