I have a 1994 infiniti j30 6 Cylinders A 3.0L SFI DOHC, a belt snapped the other night and I was wondering which it could have been, the replacement belt I bought that fit it best was a Good Year Gator Back 4040377 and I was wondering what this belt controls. And if it is okay to run the car without while i look for a shop to install it for me.
