Serpetine belt on 95 Cadillac?
Yep It has one, If your question is how to replace it, there is
a tensioner at the top between the powersteering pump and altinator
that needs to be rrelieved of tension . Use a 1/2'drive breaker bar
which fits into the square hole in the tensioner and push towards
the direction that releases tension. Remove belt. There should be a
sticker under the hood to assist in routing the new belt.
