If yuo look by the pu
lley tensioners for each you will find two bolts that secure the tensioners so the tensioner can move freeley the one you are looking for I believe was on the top and middle side of bracket on the left side of rear of engine as you look at the windshield loosen them with a socket then the left tensioner I had to use a open end wrench to loosen the tensioner pulley all the way down as there was no room for a socket wrench. I was a little challenging in all it took me an hour to replace all four belts but that was because the person who owned this car before me had left off the bushing for the alternator leaving it laying in the engine and put the bolt back on eating up two of the four belts entirely. The big trick was getting the two inner belts on first as it was so tight but once I was able to feed them in It was all good to go from there on.I truely hope this helps you by the way tighten the alternator pulley first then proceed to the two outer belts easier to hold them in place that way

How do you remove the tensioner pulley on a 1998 Saab 900 SE Convertible 2.0


Disconnect the Negative Battery Cable
2. Remove the air breather/cleaner and hose from between the air breather/cleaner and throttle housing
3. Remove the strain of the belt tensioner off the belt and pry off the belt
4. Remove the right front wheel
5. Remove the belt cover & Disconnect the battery Cable and the red alternator power wire.
6. Remove the two Alternator Bolts that secure the alternator to the bracket
7. Remove the three bolts that hold the header pipe up to help give room to remove the alternator
8. Remove the converter bolt from the converter bracket and mover the converter over to aid in the alternator removal
9. Refit in reverse

Working from Top down:
disconnect battery 2) not necessary to remove airfilter box but does give more breathing room for belt removal/instal 3) un-tension serpentine belt with a 1/2" drive long extension in the square of the tensioner & pull towards the front of the car to release the serpentine belt 4) lock tensioner with about a 4mm pin(Allen key will do) by pulling forward with that 1/2"drive extension & pinning the tensioner with that hole 5) remove tensioner with 8mm Allen key or drive(not necessary to remove R side engine mount & raise engine) and be careful to not knock and cause to release the tensioner-they hurt when they snap! 6) remove upper alternator bolt(8mm Allen key/drive).

Working from Bottom of the engine bay:
disconnect cables at alternator(13 & 8 mm nuts) 8) remove R wheel/inner fender skirt that covers the harmonic balancer(10 & 8 mm heads)/ tie back flex hose to strut 9) remove lower alternator bolt(8mm alley key/drive) 10) wedge/rotate out alternator of its mounts 11) disconnect exhaust pipe rubber hangers at catalytic converter and mid section of exhaust 12) you can bend(and later re-bend into position the hanger studs) (OR undo front header studs/nuts to free up the front part of the exhaust) to push over the exhaust and pull out the alternator(pulley nose down)--be careful when getting the alternator out as the downstream O2 sensor is right there(a good precaution would be to remove it)......reverse procedures to install.

When i first start my car theres a high pitched whining/whirring noise on saab 900s, what is that? starter problem or a belt or pulley?


The accessory belt idler pulley bearing is on the way out. Get it replaced. You will not be able to drive the car if it fails, since that belt drives the power steering, water pump, and the alternator.

I need to replace the serpentine belt on a 1995 Saab 900 s


Use a 6 or 8 inch 1/2 socket extension bar and place it in the top of the tensioner pulley, there is a notch in pulley for this. The tensioner pulley is near the firewall at the top of the engine....make a diagram of the belt routing and note which side( smooth or grooved) is lying on the pulley(usually grooved side of belt). Next you would pull tensioner pulley forward and slip the old belt off....you would route your new belt the same way and slip it on the tensioner pulley last.....you will need to pull the tensioner pulley forward again to get the slack you need to slide the belt over the pulley. I have found the Saab to be one of the easiest cars to change the serpentine belt on. I hope this helps.

Directions on how to remove the alternator on 1989 900 Saab. Does anything have to be removed to be able to get the alternator off. Also, any tricks to get belts off first?


Removing the alternator isn't the easiest job on this car!

The long bolt that allows the alternator to pivot to adjust belt tension ISN'T the bolt to be removed; remove the two bolts that hold the mounting bracket to the engine block. One is at the end of the alternator (away from the belt), the other is above the end of the adjusting bolt, not far away from the first bolt. Slacken the tension off the belt by loosening the adjusting bolt, then undo the two bolts holding the bracket to the engine block.

While you have the alternator off, check the bushings of the tension adjusting bolt; if worn/sloppy they should be pressed out and replaced; it'll extend the life of the alternator bearings.

Good luck!

Loud & piercing whinning engine noise


Your right on. Its most likely the altenator. Chances are the belt is sliping because the pully bearing is bad. Of course this all means that you are running off the battery and it is getting low. You will get stuck when you can least afford to. You must remove the altenator and replace. Oh one last thing it could very well be your water pump pully bearing. So remove fan belt and spin with your hand, if you feel resistance thats it, so remove fan belt and check before you start replacing components. Good luck

How do i remove the alternator from a 97 saab 900


You do not have to remove the wheel unless you have th 6 cylinder engine (2.3l). Then yes you do:

Disconnect Negative Battery Cable
Remove the air cleaner and hose from between the air breather/cleaner and throttle housing
Relax the belt tensioner off the belt and pry off the belt
Remove the right front wheel, black belt cover/protector, and the wheel hub nut and slide the hub off the drive shaft/outer Cv joint
Disconnect the alternator, remove the alternator/air intake hose, 2 bolts that hold the alternator in and remove it through right-hand wheel housing.

Yes, this is immensely annoying. I hope you figured it out...

2.3 900 se fan belt


The Saab fan is electrically controlled directly via the ECU and has no belt. I will therefore assume you are referring to the accessory belt that drives the power steering pump, the alternator, AC, etc. Pictures and step by step instructions are here and here. Both of these sites are also demonstrating the use of a shorter belt to bypass a center idler pulley that fails frequently (and that was eliminated altogether by Saab in the transition from new generation 900s to the first iteration of the 9-3 model).

My fan belt is loose on my 97 saab


The Saab accessory drive belt is self-tensioning by means of a tensioning pulley. The excessive play means that your current belt is spent and must be replaced. It is a very good idea to replace this pulley at this time as the bearings fail over time. You can get an aftermarket pulley of machined billet aluminum construction with a repalceable bearing race from Wazee Pulleys. This pulley is superior to the stock one in just about every conceivable way. You will need a 1/2 inch socket extension bar that will fit exactly in the top of the tensioning pulley housing and a six mm allen key. This site shows the proper routing of the stock belt and the routing procedure to bypass the highly failure prone center idler pulley if you so elect, as well as the procedure to remove and fit a new belt. Note, the belts shown on this site are for the short-belt modification only. The stock replacement belt is Part Code: 4904728 Brand: sm_bb8ca689-80fc-49cb-b9fd-7280758bc3c4.gif
Description: Serpentine belt for any 94-98 NG 900 4cyl.
