New to the site, newish to the car, wife's 2002 9-3SE needs new drivebelt and idler pulley.

I am very familiar with cars, but not with Saabs as I do 95% of the work on my 02 VW GTI VR6.

Anyhow, searching on this site wasn't terribly helpful, does anyone know if there is a DIY on doing the drive belt? I'm not quite sure how to de-tension the tensioner on the belt system.

Any help would be greatly appreciated!

Thanks in advance. :)

It's very simple. The tensioner is on top of the engine, towards the back, and has a square hole in it for a 1/2" extension. Stick one in there, pull it forwards to release the tension, and the you'll notice that a couple of holes on the tensioner will line up so you can put a small screwdriver through them and lock the tensioner in place. Most of the belt can be accessed from the top, but there's an access panel in the right front wheel well so you can get to the crankshaft pulley and pull the belt around it.

Just replaced mine this weekend. I didn't find that removing the wheelwell access panel was necessary, however removing the airfilter box really helped. Worst routing difficulty is the alternator pulley and the AC pulley. I used a wooden paint stir stick to push the belt down and then push it over the pulleys.

Expect about 3/4 hour of fiddling but really not that difficult.

I've read the removing the pulley tensioner makes it alot easier to remove the pulley.

Both are not for the 9.3 but similiar. Best of luck,

I did this to Aireeca's car following Saabtoberfest this year. Here is what I did.

1st, remove upper strut bar. 2 nuts on each shock tower, 3 bolts at the firewall. Twist up and drop down.

2nd remove air hose from airbox to intake.

3rd. lift RF wheel, and remove. Then remove the inner splash shied. 1 press nut, 3 screws.

Use 1/2 socket extension, carefully. If you brake the tensioner, things get bad.

4th. Undo belt.

5th, loop the new belt all the way around, leaving it slack at the crank pully.

6th. Pull tensioner to the forward most position, and lock in loose position with an allen L thingy.

7th, Loop around crank pulley, and re-check everything else.

8th. reasemble.

I didnt have to change the pulley, but looks easy enough to remove whith everything apart. Belt info is in the owners manual. Even the info for bypassing the AC correctly if you wish.

Many thanks those who took the time to provide helpful pictures and advice to replace a serpentine belt. There are many good posts but its tricky to find 'specific' advice for a 'specific' Saab, in my case a '99 9-3 hb, at, with ac. After sleuthing through many helpful posts it was finally clear how a Sat. mechanic like me could do it.

One tip; if you don't get the new belt on perfectly at first (the 2345 is tight). releasing the tensioner will stretch it slightly, 'and then', re-pulling on the tensioner again you can align it much easier.
