Replace serpentine belt

[roberte]

What tool or tools are needed to replace the accesory drive belt ( serpetine belt) to release the tension pulley ??? This is for a 96 Lumina 3.1

I used to have a 93 Berretta with the 3.1 and assuming that the design is the same you should have a square end on the tension pulley that you can slip an open end wrench on. I forget the size, but being a good length will help with the leverage. Fit the wrench on the pulley and pull up and slip off the old belt. Hope this helps!!!!

Mine uses a 3/8 square drive, such as a ratchet or breaker bar on the tensioner. (Mine also being a '93 3.1) Should be the same on the Gen3 3100SFI.
