Saab 9000 Belt Tensioner Compression Tool

Monday, August 9th, 2010

Update June, 2019:  I’ve just shipped the last tool I have available.  Currently we are preparing to move and all of my shop (what’s left of it) is packed away.  Also my acetylene regulator went bad and I haven’t replaced it yet so I’m out of the tool making business for the foreseeable future.

NOTE: if you are having issues with the serpentine belt “walking” off the A/C pulley or any of the other accessories there’s a very good chance your tensioner is buggered.  This happened on my ’96 9000.  The rubber bellows on the tensioner had become torn and water got into the cylinder and damaged it.

With several drivers in the family, and a newbie driver on the way, vehicle maintenance is a rather sore topic at Fairway Academy. We bought our first Saab in 1995 and the disease has simply worsened since then. The current fleet includes a couple of Saab 9000 models. Changing the serpentine belt has always been an adventure since we don’t have the special tool used to either compress or retain the automatic belt tensioner. Faced with some significant work on the latest addition to the fleet I finally decided to try to obtain one of these devices. Failing that, the next step was to simply build one of our own. It came out so well, at least as nice as the official Saab tool used to compress the tensioner, that I had a request right away from someone if I could also make one for them. Well, here it is:

I have a few of these made up and enough material on hand for a few more. If you are interested in obtaining one ($35USD incl. shipping in USA) please send a message to the administrator at

Update, March 2014:  Due to demand  I have made another batch of these and currently have a couple extra tools left over for immediate shipment if anyone is interested in obtaining one.  Glad to see there are still some 9000’s running around out there.  Also I’ve had some feedback from users about using the tool, see below for instructions.


Slot locations for attaching tensioner compression tools

Be careful to note the locations of the two notches or slots in the serpentine belt tensioner brackets, one located at each end of the spring tensioner device.  The tool is designed to be attached to these slots with the bolt end facing down, as shown below:

Once properly fitted to the tensioner bracket, use a ratchet with an extension to gently tighten the tool, compressing the tensioner just enough to relieve the tension on the serpentine belt.  NOTE: THE TOOL CAN BE DAMAGED BY OVERTIGHTENING!  I purposely designed this tool to self destruct if abused in order to prevent damage to the belt tensioner and its mounting brackets.  You bend that bugger and you’ll never get the belt to stay on and you’ll have to replace the whole kit.  Note also that the tool was designed to be used only one way, with the bolt on the bottom as shown.  If you are cheating and trying to use it from the top without taking out the wing liner you risk damaging the tool since it won’t fit as closely to the bracket as it will when oriented with the bottom down.  Note in the picture above how there is a bit of an offset between the moving and fixed parts of the tensioner bracket.  Also if you are replacing the idler pulley on the tensioner arm loosen the bolt (it has left handed threads by the way) prior to attaching and using the tensioner compression tool to avoid damaging the tool- sometimes it takes a LOT of torque to get that bolt loose, and you’ll need the belt tight in order to have something to work against.
