Belt Squel? Help please

Question

I changed both belts on my car. and then they started squeling. i tried more tension - less tension and belt dressing and they still squel how do i stop this

Answer 1

Something the belt is spinning might be seized. Make sure all accessories spin freely. It might also be the wrong width belt. Check with your parts supplier.

Answer 2

Bar soap on the belts.  Do it while running, but be careful.  Do it on the underside where the belt touches the pullys.
