Problem for Chevrolet 1990 Suburban

1990 Chevrolet Suburban....Bad noise....




By kioner - usenet poster

" "
My borther just fixed a blown head gasket in my mother's 1990
Suburban350...3/4ton...2 wheel driveThen the A/C compressor went
out
He got that fixed. The problem now is when you run the A/C a loud noise
starts...like a the engines going to blowCan't figure it out. The
pipes had alot of water in them when we started it after the head gasket
was fixed. It blew it out and ran fine. Then when we ran the A/C it made
this noise..replaced the compressor a nd lines. But it still makes this
noise..but only when you turn on the A/C...
Do you have any ideas? Thanks Baffled in Texas!

I hope you meant that there was water in the Exhaust pipes and not in the
A/C lines. If the water was in the A/C system then you have a problem.
Assuming the water was in the exhaust pipes, we will stick to the noise
problem. IF the A/c system was properly evacuated and filled to the
correct specifications AND it seems to be cooling well, the the problem
is probably that the compressor is not bolted up as tight as it should
be. A/C compressors place tremendous load on the belt and if the unit is
not absolutely secure(every bolt in its place and every strut and bracket
installed and tightened correctly), it will rattle like hell. It is
possible he installed a bad compressor right out of the box. This is
something we run across more and more these days. Check to make sure the
compressor is tight and the belt is not misaligned and if it passes that
test, have the A/C system checked out to make sure it's not at fault.

Two things that you might want to do...First hve a R12 recycler suck
the system out dry,then put in alot of refrigerant oil in the
lines.Then,reinstall the recycled freon into the system.This should
clear up your problem...moshe
