Pulley Squeal?
« on: May 22, 2008, 02:27:13 pm »
Whenever i start my truck up it usually squeals for about a second then it stops, but now, it does it when im driving. I dont think its the belt because ive put belt dressing on it. I think it might be a pulley bearing? any ideas?

Ditto, never use dressing, just replace the belt.

Mamby, Yes, change the belt. Also run a piece of 180-220 grit sand paper on the pulley grooves. If the vehicle has been sitting for a little while, a minimal  rust build-up can form on the exposed parts & cause the squeal. Lorne

i just went thru this ordeal 2 months ago;

Not only get a new belt, but get a Gates belt;  That Dayco stuff won't cut it.

Please refer to this thread regarding my plight:

Clean the pulleys, sometimes they get oil on them that never goes away on it's own.  Loose will do it too ::)
