I bought a simple little $15 belt tension gauge from NAPA several years ago
that has worked well when used correctly. Belt tension is the first thing I
check for squealing noises. You might need a new belt if it's been running
loose. If you buy the gauge, be sure and check tension at least three
times. Best two out of three readings is usually correct. I set all belts
about 70 ft/lb.

'83 300D and 240D
From: "Robert Koziak" <rkmerce...@aol.com>
I was getting ready for a vacation trip tomorrow in my 1983 300D (185K)
when suddenly my air conditioner stopped blowing cold air. The air
conditioner has been making a short squeal noise for the past two weeks.
The compressor clutch is turning and there is sufficient freon. Any
thoughts for a quick fix or guidance troubleshooting would be greatly
appreciated.
I put in a new a/c compressor a couple of years ago. It probably had 4
compressors in it sice I owner i 20 years ago.
