Slight squeaking

My truck I just bought is squeaking when I first fire it up. I have sprayed wd40 on the belt and it quietens down for about 15 seconds and starts back. It happens until it gets warm and then it stop. It's not a constant squeaking... It's got a pause in it like.......squeak squeak.......squeak squeak. Just wondering what I should try next- belt or some pulley? Thanks for the help guys!

i'd say pulley. Remove the belt and check all pulleys for play/dry bearing..etc

Ok. So if the pulleys can move around then it needs to be replaced? Any certain one give more issues with this more often than others?

When you spin the one that is dry it'll be easy to tell versus a free spinning one.

I actually have the same issue, an incessant chirpping, mainly when it's cold and/or wet outside. It was doing the same thing last year and I replaced the tensioner pulley and the belt. The other pulleys all seemed fine. No play and would free spin. I was always told never to use "belt conditioner" on them to quiet them down. After having to clean the pulleys after this was done, I see why.

Is it ok to try WD40 or something like PB Blaster in this type of situation, or will it just aggravate the situation?

NEVER use WD or belt dressing. When you put WD on a belt, it is shot and needs to be replaced. I went through this and a new belt solved the issue. Sometimes a wet belt can squeak as well but just let it dry naturally and it will stop.
Since you have used WD (or belt dressing), you need to remove the belt and thoroughly clean all the pulleys. If any residue is left, it will cause the new belt to go bad.

Wilfred, that is exactly when mine is worse also. I guess I need to pull it and clean pulleys. I will try this shortly and see if it solves my problem.
