Just wondering if anyone can provide me with the Dorman part number for the Tensioner Pully only (no sense in replacing the whole tensioner). Im assuming its an easy replacement.

Also, If im not mistaken the idler pully is part: 419-610 which id also need to change since my Lincoln Mark LT is squeeling like a pig

Well, being that its only $25 on amazon (my 07 5.4) why not replace the whole thing? Depending on how many miles the tension spring should be pretty worn givin the bearings being shot.

Im in Canada so the whole thing comes out to 80$

Ok. Either reply with truck specifics or just check amazon. There was an option for tensioner pully when i was searching. I do think itll be worth it to replace the whole thing.

I suppose you guys are right, maybe its best to replace the whole unit as its up there in KM

Do you suppose the high pitch squeeling would be coming from the tensioner or the idler pullies? If im not mistaken there are 3 of them

I get part # 419-011 (dorman) on amazon. Squealing could be any number of things. Could be the belt too.

Idler pulley is number 419-610 and is listed at $8.99. It may just be cheaper to buy at your local auto parts store.

Sorry for the jumbled reply lol. Im looking up stuff on my pc and replying on my phone.
