Our 2000 Durnago started making a terrible squealing noise whenever the
truck is initially started up and the A/C turned on. If the A/C is turned
off, the noise goes away after a few moments.
If the truck has warmed up a few minutes, the noise does not happen at all
when A/C is turned on.
I'm 95% sure it has to do with the belt. However, would it be belt tension
or indication the belt is getting old?
Would it be best to replace the belt now or use belt dressing for a while?
Will this affect the Alternator or A/C fuction at all?
