Hi all

I've got a 99 doge Grand Caravan ES, 3.8l. The problem I have is a load
continuous squealing sound coming from around the belt area when I'm not
accelerating or at a standstill. I've had a mechanic check the belts etc to
see whats causing the annoying squeal. He said the belts/tension and
everything looks good and that a piece of crud or something has got stuck
somewhere around the belts/pulleys, and that it will probably disappear by
itself over time. BUT it seems to be getting louder and even more annoying,
and I want to know if there would be any harm in me trying to spray some
lubricant (WD-40 or similar) around the pulley shaft areas.

Thoughts about other possible causes and remedies would be greatly
appreciated. Thanks in advance.

You could spray WD40 in bearing area but I would worry about overspray on
the belt.
You should try some spary belt dressing on the belt (both sides) to see if
it quietens (or use the crayon trick I did). This will tell you if it is
belt or bearing.
If beaing you should be able to pinpoint it. Try a piece of small diameter
tubing (about 2 feet long). Put one end in your ear and "search" with the
open end. If you narrow down to a bearing use a long screwdriver on the
NON-MOVING bearing bolt and press your ear against the screwdriver. You'll
be amazed at the types of noises you can hear....

It sounds like a bad belt. Only when the engine runs slow will you
hear it.

Spraying WD-40 will not hurt the belt. It should stop the squeaking,
but will not last long.

Thanks for the input guys. I'll try the WD-40 first and if that does not
cure it, I'll investigate the bearing areas.
Thanks again
