I had a march pulley installed, and for 200 miles of idling and cruising (no WOT) the belt was fine, stayed on all the pulleys and everything. As soon as I take it out at WOT, the belt was half on/half off the tensioner and power steering pulley. Still fully on a/c, crank, and alternator pulleys though ...

So is it just the tensioner or what?

 

yeah you need a pulley go to local parts store and get one from a 2000 supercharged buick regal..its the driven one. its a inch or less bigger and has 6 rib and deeper grooves all for around 20 bucks. Mine hasn't slipped since knock one wood

 

Awesome, can you still use the same belts or do you need new belts w/ the new pulley?

 

same belt

 

I wish i would had done that....I had to purchase a aftermarket tentioner due to the some reason.

 

which part store did you go to that had that tensioner pulley in stock? i am having the same issues w/my march pulley.
is there a part number you can remember?

 

This was designed for that very problem, get one and be done with it.

Went and picked up that pulley for 17.31 at o'rielly ... installed it and so far the belts still on after 2 WOT runs. I'm gonna keep an eye on it, but it seems to have fixed it!

 

And saved yourself over $100. Good job.

Thanks 8GTOKLR.

 

exactly what I was thinking ... 8GTOKLR is a savior!

 

My buddy just got one of these Synister pieces from Thunder, Billet aluminum with a nose cover looks sweet! Works great.

 

gatorback belts solved my problems

 

you guys are welcome

 

do you have the part number for that? its just the pulley you are buying right? what brand is it? i looked at autozones website and they had a few to chose from

 

Pt. # 38009 Drive Align Groove Pulley. Made by Gates Corp ... picked mine up from O'rielly.
And yes, its just the pulley.

 

I have the same problem, I think. Today Ill be getting under the car to rule out an A/C belt/pulley problem. The reason why I think theres a tension pulley problem is this: When I removed the accessory belt, I turned and tightened the tensioner and idler pulleys. The idler seemed fine because it rolled smoothly. The tensioner pulley on the other hand didnt roll smoothly. It felt as through there were sand in there. I interpreted this as a bearing issue with the tensioner pulley since it didnt roll as nicely as the idler pulley. Id prefer to just replace the pulley than to disect the thing and repack the bearings.

FstBlkz28, is the part number you provided a replacement tensioner pulley?

Thanks in advance.

 

Yup, tensioner pulley
