Car Forum / Saab Cars / July 2005`94 9000 CSE Alternator/AC belt
I bought a 1994 CSE in May. It's the 2.6 Liter engine, normally aspirated, and has the R-134 based air conditoning system. My mechanic (an independent Saab specialist) noticed that the serpentine belt was shredded and about to slip off. He recommended replacing the tensioner because in his experience that was that was normally the cause. In the process, he discovered that the tensioner had been replaced once already and that the A/C compressor was bad. He replaced the tensioner and belt, plus he gave me a compressor that he had lying around the shop. Because it was too cool to charge the A/C properly, he left it unplugged and I also programmed the control unit to always come on in ECON mode so as not to try to engage the A/C. On his recommendation, I watched the belt for a week or two, and didn't notice any problems. I finally couldn't "take the heat" and went back to complete the A/C charge. My mech immediately noticed that the belt was once again about to come off. He is pretty much mystified, and can only offer that a new compressor "might", stress "might" solve the problem. Besides the $750 for a new compressor, it turns out that there are none available in the U.S. for another few weeks. Anyone have experience with this problem? > I bought a 1994 CSE in May. It's the 2.6 Liter engine, Not possible. No such engine. 2.0 or 2.3 litre only. Graham >> I bought a 1994 CSE in May. It's the 2.6 Liter engine, > > Not possible.

The only 4-cyl. is the 2.3 from about 1991 on. > I bought a 1994 CSE in May. It's the 2.6 Liter engine, normally aspirated, > and has the R-134 based air conditoning system.

Since a pulley comes attached with the compressor, we tend to discount that problem at the compressor pulley. Other pulleys? Maybe. I can't think of any way to check, either. > > > I bought a 1994 CSE in May. It's the 2.6 Liter engine, normally, > ^^^ 2.3 [quoted text clipped - 33 lines] > that problem at the compressor pulley. Other pulleys? Maybe. I can't think > of any way to check, either. There's quite a few pulleys on the 2.3 engine serpentine belt IIRC.

I am not quite sure what you are saying about the "Econ" button but it is supposed to shut off the compressor while you remain in the "Cooling" mode to let you get controlled comfort using only cold outside aide.Do not put the system on re-circulate. And what is this about too cool to change the a/c ? Does this guy have any idea of what he is doing?

It seems you understand. Never mind. > And what is this about too cool to change the a/c ? That puzzled me. Never heard of such a thing but I've not yet needed my a/c recharging. Maybe his engineer is stringing him along ? > Does this guy have any idea of what he is doing? Your guess ? Graham > I finally couldn't "take the heat" and went back to complete the A/C > charge.

Also have him check the alternator. I had a Fiesta that was eating belts. Turned out it was an alternator on its way out. There was no other sign of a problem other than belts disintegrating. > > I finally couldn't "take the heat" and went back to complete the A/C > > charge.

Graham > That's an intruiging scenario. > > Any idea how the alternator was doing that to the belt ? From what I understood -- which wasn't much because my mechanic was Korean and would start swearing at me whenever I brought the Fiesta in for repair which is understandable if you've ever tried to work in the motor compartment of a 1980s Fiesta -- the alternator spindle/pulley would slow down/seize up or otherwise put friction on the belt. They replaced three belts in three weeks before figuring this out. After replacing the alternator, everything was fine. |
