One annoying squeak has been tracked down. With the engine running and the
A/C off (it doesn't seem to work anyway), I can see the A/C clutch turning
slowly with it's pully. Not at engine speed, it lags behind quite a bit. At
one point of it's revolution it squeaks, once every few seconds or so. I can
touch it with the handle of a breaker bar and keep it still with no effort
which silences the squeak. Turning the A/C on does absolutely nothing. I had
attributed that to a low/leaky system but maybe it's clutch related. So two
questions: How is it even possible for the clutch to behave in such a way,
and how do I shut the damned thing up?
Sounds like the clutch gap is too tight. You can use a clutch puller to
adjust the gap. It may also be that the compressor failed internally and
damaged the shaft causing it to shift and the clutch drag. What does a
set of AC gauges show?
No idea what gauges would show. I had assumed a leak and the system was
empty until I noticed the clutch misbehaving. There isn't a lot of room down
there to get a puller on the clutch. Maybe through the fender well but going
by memory I doubt it. At the moment I just want to shut it up, the lack of
A/C isn't a huge concern. I guess a shorter belt might be the simplest
this is classic v-5 clutch drag- the clutch has corrosion built up in
behind the rivet head "stops" not allowing it to fully disengage...
Had the same problem on my 00 Century, sprayed the rivets with WD40
and it dislodged the rust.
No more scraping.
Could not get a puller in there with the compressor on the car.
Worth a shot.
Not penetrating oil - WD40. WD40 does a good job of cleaning up light rust
and won't leave a residue behind. You won't have to worry about your clutch
with it. WD40 should never be confused with a lubricant - it is not a

Yeah, I know what the manufacturer claims. Once the carrier dries though,
you've not got a good lubricant left behind. It functions much better to
displace water and lift rust than it does as any kind of lubricant. Hell,
while it's still wet, water even makes a lubricant. Doesn't make it a real
Most penetrating oil isn't much of a lubricant either. I figured I'd hit it
with some PB Blaster, it tends to dislodge rust too. If WD40 would do a
better job then I'll use that instead.
Agreed, WD40 makes for a LOUSY lubricant long term.
