I just changed all my drive belts (POWER STARING & ALTERNATOR BELTS) and installed an refurbished alternator all at the same time. When I start my pro up it makes a SQUEAK SQUEAK! sound that drive me frigin nuts. I checked all the belts and thay look fine to me

any input would be Appreciated.

 

get some belt dressing, comes in a spray can usally and run the car and spray it on the belts directly(dont be shy load it up) to see if that quiets it down, the belts may need time to ware in
hope that fixxes it for you, best of luck, oh btw a can of that stuff is cheap like 5-10 bucks and lol lasts forever
