Squeal when truck starts... anyone know???

[Mikes95XLT]

I know there was another thread about this, but I couldn't find it.... so I'm asking again here.

When I started my truck this summer after sitting out at night, there was a small squeal really quick, and that was it for the rest of the day. But now that it's getting colder outside, the squeal is louder and longer when I start the truck, and I don't know what it is or what to do about it. Anyone know??

check your belts..

It's probably your tensioner pulley. If you remove your belt, you can try to spin the pulley by hand and listen, and you can also check for play in it.

If the pulleys are shiny, the belt is starting to slip. Push down onn the belt, if there is more than 1 inch of play, then it is too loose.
