Belt squeal

I have new belts on my CJ7. I havent been driving it much but now that I am starting to the belts will squeal from time to time right after start up on high speed idle. They usuallyi stop after a short distance but its annoying and embarrassing.

What causes this and whats the best remedy? Seems I remember a friend putting bar soap on the underside of his back in highschool. Not sure how smart that is

Belt could be loose? I had the same problem, adjusted the alternator and problem went away, you can also buy a belt conditioner from the parts store.

Too tight will also cause squealing and could potentially damage bearing in your alt/PS pump. You want about a 1/2" of deflection on the belts when you press down with 1 finger on their longest unsupported run (ontop).

If the belts have glazed over, they need to be replaced. Check the pulleys to make sure they are not coated in something.

Get a bar of canning wax at the grocery store, or a candle, and while the engine is running, CAREFULLY apply the wax on the inside of the belts. Works like a charm!!
