#30 of 78 Re: Can't check AC compressor for 1998 Plym Voy.
May 11, 2008 (6:36 pm)
I purchased a 1998 Plymouth Voyager Expresso 3.3 engine last week. I also purchased the Hayes Repair manual. It states in order to put R-134 in, the compressor has to be running. If not, jump the LOW PRESSURE CYCLING SWITCH with a jumper. It does not show a picture of what it looks like, nor where it is located. Can any body please clue me in on the exact location and what it looks like? Thanks in advance.
#31 of 78 Fan belt squeals
May 16, 2008 (4:39 am)
98 Caravan: Replaced serpentine belt at about 100,000. Belt squealed when A/C is turned on and intermittently at highway speeds with A/C on. Had belt tightened, temporary relief. Belt began to squeal again when A/C turned on and intermittently at highway speeds with A/C on. Did not squeal with A/C off.
Replaced belt. Temporary relief, but squealing began shortly again.
Have had this problem for 50,000 miles and mechanic does not seem to be able to figure it out.
Now the belt squeals when ever the A/C or the heater fan is turned on and squeals intermittently at highway speeds with either A/C or heater fan on.
I love my mini van, but I am afraid the belt will break in some desolate place or worse. Any suggestion would be greatly appreciated. Thanks

Had belt tightened, temporary relief. Ummm, these vans have a spring loaded "belt tensioner", so unless you had your mechanic replace the tensioner with a unit that has a higher tension, then there is no such a thing as "tightening" the belt.
Over the years I've read about many belt issues on these vans and squealing is almost always one (or more) of three different issues:
1) Cheap belt. I've personally had to deal with this one, I was too lazy to replace my own belt a couple of years ago and so when it was in for the annual state inspection, I had the shop put a new belt on. Needless to say, they bought the cheapest belt they could find. Damn thing squealed from Day 1. I finally got tired of the squealing and bought the best NAPA belt sold and put it on, squealing gone and has remained gone for the last 20,000 miles.
2) Oil, Power Steering Fluid, or Coolant contamination: As engines and accessories, age they tend to leak, fact of life. Check to see if there is any contamination on the belt surfaces.
3) Failing or failed A/C clutch or compressor. Of the two I'm thinking that the compressor is most likely. Do you hear any noise or racket emanating from the compressor when the A/C is working?
Edit: It just occured to me that you might have a 4-Cylinder engine or the Mitsubishi 3.0 liter V6, all of my comments were made assuming you have either a 3.3 or a 3.8 liter Chrysler engine. If you have either of the two smaller mills, disregard my comments.

Thanks for your input. I should have been more definitive regarding engine.
The mini has the 3.0 engine.
Question: does this negate the "spring tensioner"/ belt tightening observation?

"Question: does this negate the "spring tensioner"/ belt tightening observation? "
Ummm, I don't actually know, even though I've worked on many-many Chrysler minivans, I've never even seen one with a 3.0 liter engine.
I'll ask around and if I come up with something, I'll post the results.

I have the same problem with my van. Have located the switch? If so, how do you go about jumping it?
#36 of 78 AC/transmission GROWL
Jun 21, 2008 (2:27 pm)
'97 GC Sport -- Runs perfectly unless the AC is on. Then I hear a growl that sounds like it is coming from the transmission. This more prominent from a standing start that at highway speeds. However, I can make it stop at any time by just turning off the compressor.

1) The growl isn't coming from your transmission.
2) The growl is coming from your A/C compressor.
Keep us posted.

Seems logical. But then why does the growl not continue at highway speeds? The compressor is still engaged.... But I can't hear any growl.
It is also not audible at idle.
But upon acceleration, it is quite loud.

Why not on the freeway? Probably because of too much wind noise, and/or the RPMs are too low.
Why not at idle? Probably because the RPMs are too low to cause the compressor to make the noise.
FWIW, compressors get noisy as they age. The compressor in our 1998 DGC is starting to get a little loud as well, and that is causing me to consider a prophylactic replacement before it grenades. FWIW, when compressors go, they usually send lots of shrapnel around the cooling system, and that stuff is a pain to evacuate, and if it isn't done properly, then the debris can cause replacement compressors to grenade as well.
