Car Forum / Ford / Ford Explorer / July 200497 SOHC serp belt problems
I changed the belt a few weeks back, now it's started squealing just as I start the engine but then it stops. I removed it and degreased the pulleys, but that didn't help much. Funny, it never ever made a sound with the old belt. It is a Ford belt, not aftermarket. While doing this I discovered the idler pulley at (about) top center wobbles slightly and isn't particularly "smooth" when I turn it by hand. Is this normal? I assume not, but before buying a new one I thought I'd ask around. I have the original tensioner, which evidently has been a lot of trouble for many, but mine seems to be OK. thanks... Herb, Aggravating huh. I have had these belts squeak too, for no apparent reason (both Ford and NAPA). A continous squeal indicates something is not right. Rec make sure all pulleys are rotating freely, aligned and of course clean. The idler pulleys are sometimes a single ball bearing roller and will wobble with no belt installed. But it should rotate smoothly. The idler tensioner should be free and be in the correct tension band (an indicator on the tensioner). You might also try washing the belt in soap and water before installing. never use "belt dressing"- it makes it horrible. Good luck, Jerry > I changed the belt a few weeks back, now it's started squealing just as I > start the engine but then it stops.

Might have some residue from the belt manufacturing - don't know if they are molded someway, but it they are some of the releasing agent could be on the surface I guess. > Herb, > Aggravating huh.

The Ford serpentine belt is good and there is no residue on the pulleys. The local Ford tech has given it a clean bill of health. I guess it's just an Explorer idiosyncracy that you have to live with. Steve R Nah, it was fine for 6 years. There's more to it than that. I wish I hadn't thrown out the old belt. It would be nice to put it back on and see what happens. > My '00 SOHC has squealed on every cold start since I bought it two years > ago.

Now you tell me :>| My Dodge truck's belt squealed on cold damp mornings, so I juiced it up one night with Krylon belt dressing. It quieted right down, until... the next morning it absolutely shrieked! For 8-10 miles it sounded like super-sticky duct tape being ripped off a roll, nonstop. Herb, Aggravating huh.
