i have a 91 gta 5spd. I recently removed the air pump installed headers and march underdrive pullies.I CANT get a belt to fit! i have one close but where the belt rides the tensioner it also hits where it rides the water pump and smokes the belt.So i can go an inch shorter but then the tensioner is maxed out and i dont know how this will hold up over time.
Please help me ive got alot of money in those pullies and really dont want to take them back
THANKS

 

I'm guessing the underdrive water pump pulley is larger in diameter than the factory one. I've also got my smog pump removed, and using a stock length belt it is very close to the water pump, probably 1/2" or so. A shorter belt should move the tensioner pulley farther up, and away from the water pump pulley.

 

thank you, yes i guess the water pump pulley is a bit larger. I hadnt thought of that being an issue but makes sense now so i will try a shorter belt an see. I just dont want to kill the tensioner being so loaded
