g96nt well, that's your problem, right there!

vieka Hey everyone. Thanks to your detailed instructions I was able to do this by myself in about an hour and a half.

I have a 2003 Saab 9-3 Conv. For the belt I used part Duralast 710K6 and for the Upper Idler Pulley I used part Duralast 231095. $40 together at Autozone.

I didn't take the wheel off. But, I did jack up the car from some extra elbow room to fish for the belt. The tensioner was fine, released the tension to get the belt off, and then again to get it back on. Car is running great. No more noise, white smoke, or rubber smell.

Originally I was only going to replace the belt but saw the idler pulley. Attached a pic.

Svenska94Aero Can anyone tell me quickly, is the 2325mm belt the right short belt for a B234R? Need to bypass A/C on my Aero tomorrow. Thanks!

oct4th Hey guys. After a successful short belting on my '99 a few years back, about to do the same on my '01. The serpentine belt decided to eat itself a couple weekends ago. My question: I'm not positive that the AC is to blame. With no belt on the car right now I can spin all of the pulleys EXCEPT the AC. It won't spin at all. Should it spin? I'm going to short belt it just in case (fall is on it's way, right??) - but next summer I may throw the longer belt back on, just to see if the AC is really the issue.

Anyways, anyone recall if the AC pulley should spin freely? Thanks!

fiveiron9688 Now, what if I want to bypass my center idler on an NG900, but bring back the A/C? Can I just buy the 9-3 belt?
03-10-2011 06:53 PM
turbo900se So does anyone have a diagram on how to run the new belt? I looked in the manual but couldn't find it. Also do you have to remove the center idle pulley also for this or just the ac?

WSW I picked the 1815mm one, and its been holding up for quite a while now
12-30-2010 08:32 AM
fiveiron9688 Well, I went with the 1805...seems fine right now, but the tensioner didn't go back as far as with the stock belt. So 1815 would be a safe choice I think.

I'm bypassing my rattling A/C and the center idler pulley...but I'm wondering if my 1998 NG900 would be considered one of the "last ones" and have the 1815 mm length rather than 1805...

zef This works on 9-5s too. 1816mm belt from O'Reilly's, bypassing both the A/C and the center idler. Thanks for the info in this thread.

seriks1 my 99 9-3 worked perfectly with a duralast belt from autozone 715k6 (71.5 inch 6 peak). Lots of parts folks don't know what the #s on belts mean. Also 5060715(gates) k060715 (goodyear/gatorback). For the 900s try 710k6, 5060710, k060710 (71 inch 6 peak).

Somewhat related item ng900 with a/c minus center idler 960k6, 5060960, k060960. Same idea, 96 inch 6peak. You can use a 955 here, but it's tight.

IX III yeah so i'm pulling up an old one....

I have a 99 9-3, replaced the tensioner after i snapped it following the rebuild.. oops.
so does that leave me at 1805 or 1815?

i have a 200mile road trip coming up and the ac compressor sounds like a rock tumbler.
i'm going to pick up a spare to toss in the trunk for the inevitable roadside repair.

'97 Saab SE Turbo Ok, I see. For some reason, I thought that the belt from the PS pump came straight down and under the water pump pull instead of over the top of the water pump pulley. I already have the idler delete short belt mod, so I guess it wouldn't hurt to carry an AC compressor delete belt just in case. Thanks... Ron

JK You must be missing something, it isn't going to spin the water pump backwards...

I think this diagram shows the routing sans A/C compressor, just the PS and O2 pumps. Correct me if I am wrong...

However It does show the center idler pulley which I think a lot of people just bypass as well.

'97 Saab SE Turbo Hi, new poster here - not new to Saabs, just new to this forum. I'm curious about bypassing the AC compressor. It looks to me that if the AC compressor is bypassed, the serpentine belt still goes around the top of the PS pump pulley, then under the water pump and on to the crankshaft pulley. If this is correct, the water pump will spin in the opposite direction. Am I missing something here? TIA... Ron

oct4th Thanks for the speedy reply and the welcome!

Only question: our compressor is actually working great - we had to bypass the pulley because the pulley bearings were starting to go and we didn't feel like spending a grand (at a shop) to replace the whole unit just to fix a stupid bearing.

Is there any danger in killing the unit if we leave the fuse in? I'm hoping at some point we might work up the nerve to just try and replace the bearings ourselves, and I want that compressor still working when we get around to it!

09-09-2009 03:52 PM
aireeca Looks like fuse J in the engine bay for the AC compressor. Although, I left it in, no big deal.

Welcome to the site and glad we could be of some help!
