How do you change the serpentine belt on a 1998 Pontiac Grand Am?

The 1998 should be the same as the 94 there is a tensionometer that a 3/4 rathet will fit it. If you are standing in front of the engine look to tleft where the belt is and towards the back. It looks like a 2-3 in wheel. Put your ratchet or breaker bar in the square and pull this should loosen your belt
