i have a 04.5 cummins and i have a squeal under the hood pretty much all the time. i changed the belt less than a year ago so i dont think its the belt and the sound is coming from the bottom left of the motor and i watched the tensioner and it appears to move a bit while the motor is on. does this sound like it needs replaced and would i need to replace the whole thing or just the pulley? is there a write up on how to do this or can anyone walk me through it that have already changed one? thanks

i'm wondering the same thing. mine has a pretty good squeal most of the time as well. in my case my belt is fairly loose so i figured i'd get a new belt first. and while its off im going to turn all the pulleys to see if i can find the noise maker. but thats a good question about replacing the entire tensioner or just the pulley?

the tensioner will have some small movement due to tension changing but nothing major, i would recomend taking belt off and spinning all the pulleys and pinpoint noise. :thumbsup:

if your belt is loose then the tensioner is not doing its job. replace tensioner i would replace the belt as a pm reason.
:thumbsup:


also to see if is just belt noise, you can take a SMALL amount a/b 1/2 the size of a dime of black rtv and put on belt ribs, if the noise goes away then its the belt. replace it.. :thumbsup:

X2, pull the belt and check individual components. As far as changing the tensioner goes, all that you need to pull is 1 13mm bolt and it drops right off of there. I did mine today, the pulley was wearing funny. Easy 20 minute job, the hardest part is paying for the new parts.

are you able to do this without removing anything else like the shroud or radiator? its pretty tight in there

I went up from the bottom, didn't have to remove anything else to get it out.

Replace the tensioner pulley, had the same problem and that was it.

Pull the airbox and take the tensioner out from the top. Will save lots of headaches and scraped knuckles.

the tensioner bolt takes a 13mm wrench to remove pull it out and it will come off then put the new one in takes one bolt and one alignement nipple. then just shove your belt on and your done. i did myn in the freezing rain in 12 degree weather with no jacket in about 25 minutes. its no big deal.

170 ish from NAPA. The NAPA tensioner was way beefier than the dayco I pulled off, had a metal pulley, not plastic.

ok now it seems whatever was making the squeal, doesn't squeal when i plug the truck in over night. starts up fine with no squeal. only squeals when its started cold. so i dont think that would be belt tensioner. any other ideas?

Replace the belt and pulley if you haven't, that solved my problem.
