So here is a run down. I replaced the belt ( OEM ) about 1 year ago, it now has about 7500 miles on the belt. Its been squeaking here and there but this is where it gets interesting. The belt will squeak at cold idle like a slight chirp but now its more like a faster chirp/short short squeal. Once the truck has been driven for a while, there pretty much isnt no noise. If i spray soapy water on the belt, it'll stop instantly but then squeal a bit here and then ( this is when cold ). Id attribute that to the soap wearing off the pulley/belt.

The truck has 76k on it, and I was thinking about replace the tensioner. I can get one from Amazon for 73 shipped and its OEM. What Im wondering is, what other bearings should I replace in the idler pulleys? I dont know how many there is, nor do I know what bearings are needed for those additional pulleys.

Has anyone done this?

If you could list the bearing and the qty needed ( minus the tensioner, I'll swap that new )

I would do the other 2 idlers while you’re there. One comes on the tensioner, then you have one up by the intake and the other over by the coolant thermostat neck

Thats the plan, but Im going to buy a complete new tensioner. Mine has good tension, but 70 bucks for a new one/properly tensioned belt is okay by me.

I just need to know what the bearing numbers are one those two idlers, I have an idea, but I dont want to clutter up the thread with improper part numbers in case someone else comes along.

Not sure if its here or not, buy check through here.

You can look the numbers up and or buy them from rock auto, or one of the Ford vendors on the site will hook you up. At least give them a try. Sean @Sunrisefordparts got me a good price on my CAC

They won't sell just the bearings. I'd have to buy them from McMaster etc

Sorry, I was thinking about the pulley assembly. I just replaced the bearing in one of my pulleys, bearing part #6203. I think it was on the tensioner though, so not sure if it's the same. Might want to pull yours off and get part number then reinstall till new ones come in

I think @ZMANN had a list somewhere.

Yeah I think Its 6203 and 6202 ( 2 each, but I dont know... ) but Im replacing the tensioner and thats one or two bearings that I wont need. Thus I dont want to buy a bearing and not need it...

Ive read somewhere that Gates updated the pulley to be better, and now Im thinking about just buying them from Rock Auto..

I'm going to do this relatively soon. I'm just going to stick these posts here so that I have them for later. ...and in case they help anyone else. I made the attachments from the 2004 Service Manual.
