I have a 1994 GM V6 Saab 900.  The lower radiator hose has a hole in it
where it rubs the exhaust pipe.  My question is if this was by design. I
would assume no one would design an car where the rubber radiator hoses
are in direct contact with the exhaust system - but one should never
assume.  I would think this is either the wrong hose or there should be
a bracket to keep the hose away from the exhaust pipe.

Its a good thing I have my C900, so I can take my time fixing the
"Newer" GM 900 - again.  I just got the GM900 out of the shop two weeks
ago.  It was making a clunk everytime I applied the brake. Fortunately
it was not the brake. I was told it was a common problem with the
GM900s.  The A-frame is attached to the uni-body by bolts, which
routinely work loose.  The clunk was the A-frame moving. I will know
where to look the next time it starts making noises again.
