1988 s10 tahoe 4.3 v6 new air compressor, new belt derailed at compressor within 5 miles, tensioner replaced, belt replaced, belt came off at compressor again within 5 miles.
Both times truck was in reverse backing out, if this makes a difference.

Any type of noises before it derails? Alignment of the belt is it okay by looking thru the side-When the compressor is locking up could snap the belt too-
