I see other threads on this - non specific to a 9000. Not sure I know what the problem is
Just want some wisdom from a serious SAAB mechanic. My 9000 has done 110,000 and has started eating serpentine belts. The second just failed after a few 1,000 miles. I had had no problems with the first one, just renewed it. All the idlers and the driven pulleys appeared free spinning and also non wobbly. But that didn't a save the new belt.
The tensioner was also tensioning, needed serious force from the compressor to loosen it. etc.
Is their something dark and lurking to check? Do the actual tensioners fail/get weak? My last 9000 did 200K on the same pulleys and tensioner.
Off to remove the wheel arch cover and dig out the remains of the last belt from around the crankshaft and alternator, as this one failed in a bad place and really got devoured, I couldn't free the remains and neither could the RAC... had to get trucked home.... hope the pulleys don't have to come off.....
I have to buy a new idler wheel as the old one is coated with remains, the RAC guy said. But it spins freely...... that's about it. What to do - buy a new tensioner unit anyway? etc. Never had a problem like this with such belts before on any of the family cars.... thanks for any insight.
