Belt sqeuaking

Little bit of history first. In october i was in a bad front end accident. Mostly the body and the radiator were damaged. When i picked up my truck from the shop the belt was squealing. I thought it was just becuase it hadnt been driven in awhile. It didnt go away so i tried belt dressing. That only worked for about a 30 minutes. i took it back to the shop and they said there was no damage to the pulleys but that maybe some fluids got on the belt. They changed it and i have had no problems for months until a couple days ago. The new belt is squeeking again. It starts between 1600 and 2000 rpms. belt dressing seems to make it to help shortly but it comes back and worse and it doesnt start until after ive been driving for about 20 minutes. Should i just put on another belt or should i examine the pullies more? (sorry for the long write up).

 

yeah i would check the pulleys, maybe the tensioner also. but it shouldn't keep squeaking like that in such a short period of time

 

maybe just need to be tightened?

 

If the belt has already been changed and it doesn't help, try replacing the pulley.
