Squeeky Pulleys
I am having a problem with my pulleys. Every morning when I go to warm up my truck I'll start her up and the damn pulleys squeek for about 5-10 minutes and then stop. I'm not sure if it is one pulley or all. Have any of you had this problem and if so how did you solve it? What type of lubricant do you suggest for the pulley bearings?

First thing to do is determine whether it's the belt slipping or a bad bearing. You should be able to tell by taking a good look at it while it's squeeling. Most likely it's the belt slipping.
The belt is tensioned automatically, so if it's slipping it's likely your belt is worn out. A replacement belt is about $70 CAN, so the best bet is probably just to replace it. You could also try spraying the belt with a "belt dressing" lubricant, it might help you get a few more miles out your existing belt.
Use a bar to back off the tensioner, remove the belt, and check all the pulleys. I'd start at the alternator. This is a good idea at any rate, as it'll let you inspect the condition of the belt.
Let us know what happens, or if this doesn't help.

It might be your altenator!or its bearings, just after starting your altenator will cycle( internal voltage reg).
The tensioners have been known to go bad ,the spring will crack,and squeek.How many miles on your truck?

If it sounds like a train whistle, I have the same thing happen with the cold weather. The dealer "fixed" it last year shortly after buying the truck. Said it was due to paint overspray on the idler pulley. They put some scotchbrite to it to clean it up. It helped but it didn't eliminate the whistling completely. Nothing has seized so perhaps it isn't that big a deal. Just annoying.

>Its definetly not the belt. I will check out the tensioner.
Are you sure the belt is not glazed? If the belt is kind of a blackish brown color and real shiney, replace it, it's burnt.
If you can get a wax candel to the belt with it running(and without sticking your hand in the fan) coat up the belt with the wax, if it shuts up, the belt is bad.
If these don't do it, check the pullys out, one of them is probably on its last leg. My bet is with the belt just being old and slipping.
Hope this helps

[updated:LAST EDITED ON 04-Dec-02 AT 10:25 AM (EST)]The truck has 25,000 miles on it. I guess I'll check for overspray on the pulleys and check out the bearings on the pulleys. I will have to take the belt off to do this so I might as well slap a new one on there. Thanks for the help. I'll post what happens. Anymore suggestions welcome.
