03 H6 serpentine belt pulley torque

Featured Replies

Evidently, these pulleys have bearings that fail prematurely. My wife has heard squealing a few times and this weekend, I plan to change the bearings in the idler and tensioner pulleys when I change the serpentine belt.

 

I just haven't found any torque values for re-installing the pulleys.

 

thanx for any help.

very few people would torque this bolt, it's benign. snug so it doesn't come off will do it.

 

i have been checking every H6 i come across and so far every one has needed at least one of the two bearings replaced. i consider these maintenance items, you're definitely doing a wise thing to replace them both.

 

i'd like to know why they're failing so frequently.

Yeah, I figured I'd either just pick some number that seemed appropriate for the bolt size or just wing it by hand if nobody has a value.

 

thanx

that's how this one is done, there's so many bolts on a vehicle that you have to learn which ones torque values are important for and which are not - but values are most helpful if you're not comfortable, new to this sort of thing. have to learn somewhere what "that tight" means. hard to communicate those things over interwebs. :drunk:

Yeah, I did a lot of work on cars in the old days without one and never had a starter or wheel fall off, but, dang it, I paid for the thing, I wanna use it! lol!

well i did come home and look for the FSM but can't find my H6 FSM...which i thought for sure i had, scratching my head.

Got those done this morning. The old bearings felt rough but weren't wobbling. And the tensioner pulley's bolt seemed loose - well, not tight, as in, easily removed. weird.

 

not as easy as an oil change, but much easier than struts!

just bumping in case anyone else needs the torque values; both seem to be 25 ftlbs.)

The noise is still intermittently occurring. After reading that sometimes the o-ring/hose connection to the PS Pump can allow air to be sucked in and cause noise, the next time I drove her car, I exercised the wheel from lock to lock, as the pump would strain at the limits, she says "That's the sound I heard!"

So, I need to investigate that hose deal.
