Starter up squeal

Postby ddfarm [OP] » Jun 28 2013, 11:08am

I have a 2000 chevy 3500 dually 7.4. When I start up the truck, there is a brief squeal (.25 second)coming from somewhere under the hood. I thought it was the belt so I changed it but it is still there. It only has this squeal about 50% of the time and only happens after it has sit 15 minutes or so. This squeal is brief and only last a split second. I it sounds like a belt slipping, up now I wonder if it could be the starter hanging for a split second and the sound is not really a squeal at all. Having a lot of trouble diagnosising the problem. HELP!!!

I would suspect a weak tensioner spring. I'd replace both the main and A/C tensioners.
