the install went fine but its been about a few months. my question is, the belt.... should it leave shavings all over the place? and it squeeks a lot every now and then depending if i use the A/C. i apply belt dressing to the belt and it stops for a while then starts making noises again. i tighend to the specs but still noise? iam thinking i did somthing wrong because i dident realy feel a performance boost after applying

hey, just wanted to know what size belt did you use?
thanx

Belt dressing is awful, it'll ruin your belt... As for the Pulley, could be the coating on the coming off, i would clean them off the belt. Also, did you get a 450K5 (think thats the belt) for the car instead of the 455K5 thats stock? The belt could be too big and loose for the car, thus the squeak.

the belt you need (reading from package) is either 4050457 or 5PK1160, the beter everyone else is suggesting is a @!#$ bitch to get on, the one I listed is perfect.

you A/C compressor clutch could be going.

if the squealing only happens when you turn the a/c of, then its not the belt, it is (as ur weak said) the a/c compressor clutch on its way out. the a/c will still work, but when you turn it off, it wont completely turn off, because the clutch wont dissengage all the way. i am actually in the midst of that very same problem... the clutch on the a/c compressor in my car is on its way out, and i found that it could be a very VERY costly fix to have someone do it for you... but the a/c sounds more like a hissing than a squealing, which makes me think differently about it being that..

hummm ... thanks guys.. as for the belt i used ... i couldent get the one that unorthodox recomened.... so i had to settle for a no name brand belt.... its a dayco polycoc p.n. 5050450 but its shreading down.... so i asume it was a bad idea to get this belt? the stock belt just did not fit at all... even with the tensioner pully released all the way it still couldent even touch the belt =P.

also i should get rid of the belt dressing?

use the belt I listed above, and you wont have any issues

If you use the proper belt (450K5), you won't have any problems. It sounds like you've used a belt that was too long, and it's now stretched to the point that it slips. Belt dressing is a band-aid solution, and makes a hell of a mess... as you've discovered.

I realize that the proper belt is hard as hell to get on there... the best way I've found is to get the tensioner from the wheel well (not the top, as you don't have enough room to open it up nice and wide), then turn the crank pulley bolt with a socket and ratchet.... roll the edge of the belt onto the crank pulley and "walk" the belt on.

I had the UR pulley on my silver car, my white vert, and then the red vert (prior to supercharging it).... never had a squeaky belt unless I used the wrong size belt.

well the belt is very tight.. to the point that i had to crank the engine over to get it on. so i dont think its too big.. i think its too small or it could be the fact its just a cheap belt. also, just wondering ... did you guys notice a huge difference in accel or RPM rev after installing the pully?

Did you get the correct belt and it work itself out?

I'm starting to have the same problem with the a/c on or off.
I'm using the RSM UD pulley.

I'm sure its the belt, cause it was really easy to install this time around.

So change the belt?

Remember....syringes go in the RED waste basket.

I have never used that pulley, but I have used a 2.3 pulley as well ebay pulley (currently) all I used the 450k5. Easy to get at Autozone (in a gatorback) for about $18. Yes it is tight getting it on but no issues. Make sure the pulley is on all the way. Check the bolt and make sure it did not come lose and is wearing the belt. Make sure all pulleys are in line with each other. also make sure the belt is not off one of the grooves. If all that is ok get another belt (450K5) and reinstall it.

Cool thanks,
I figured the Gator brands would be the correct one.

And I'll check the bolts.
Friggin thing is only 11 oz.

All else fails, I'll just use MD LD9 factory sized combo with factory belt.

Remember....syringes go in the RED waste basket.

Ok went to Autozone.

For gator belts... the part numbers were 450480 and 450470.
No "450K5"

Other belts were 470K5

Now they did have one from Duralast 450K5.
Its hella small, but I'll try it and see what happens.

Well I have always went to autozone and said I need a 450k5 and they gave me a gatorback belt. Maybe the guy knew what I meant and knew the part number conversion. I worked at PepBoys and all belts had the same number (450k5 etc..),but we had our own in store part number (like :11450). The 450K5 is the correct belt you need.



FU Tuning

Yeah I figured it out.

If I want the 450K5 gator I'd have to get a "450450" belt.

And at Pepboys all the belts are right there on the shelf so I can just compare that way too.

But we tryed to install it. no luck.
VERY TIGHT and hard to get on there so I'm gonna take it to the shop..
But.........

I'm a little weary about having it installed.
If the tensioner has to be leaned so dam far back to get it on.
There belt will be sooo dang tight I'd be afraid of it snapping.

Gonna try a 460 belt first.

Thanks for all the help.

Yes it is very tight, but it will go on. Trust usthe 450K5 is the correct belt.

Well gonna put this thing to rest.

From my initial reading about this pulley over the years, the general consensus was a belt "2 inches smaller than factory"
Ok fine.

The factory belt numbers come up as 475K5 or "450475" or whatever.
Bottom line its 475 length.

So, for 2 in shorter you're looking at 455K5 or 450455 or you get the idea.

Now from my understanding, the pulley itself is a factory sized 2.3L pulley.
Doing that you get a pn: 470K5 or 450470

So 2 inches shorter is of course 450K5 or 450450

Which I guess if the real question.
What kinda specs are the companies basing this pulley from exactly?

Oh well,
Right now I have the 460 belt.... 460K5 or 450460 ont eh car now.
Much tighter.

I"m gonna leave it as is, since I have the lightened factory pulley combo coming.
By then I KNOW what's the correct belt.


Thanks for all your help guys.
