Question about 1991 Nissan 300ZX
I have a 1991 Nissan 300ZX that has a squealing belt. A/C, Alternator and Serpentine belts have been replaced. It squeals for a few minutes at start up, then quiets. It also squeals when running the A/C. Any ideas?
I would check belt tension and then Idler pulley bearing..If still nothing check the A/C compressor clutch..

Try spraying one item at a time with WD-40 or belt dressing. Try not to worry about doing the belt first and save it for last. Most causes of squeals are galzed belts from being too tight or the pulleys of whatever item, the bearings are going out or were improperly lubed.
This is the cheapest method to truoble shoot the annyoing noises.
Hope this helps!
