However ester (or POE) is a good choice because it does not interfere with the old mineral oil in the system.
I knew there was something about compatibility, thanks for clearing that up and sorry for the confusion.

Looking at the service manual, it looks like both tensioners are attached to a single bracket... Unfortunately you have to remove the alternator, drain the coolant, heater hoses and pipes, power steering hoses, and power steering pump to get to it.... Looks like a pain.

From my remote diagnosis earlier, I still doubt a bad tensioner, but I'll default to Fuddy, who actually looked at the car. My gut tells me that tensioner is simply a symptom of something else on that belt path.

Is it possible to simply replace the spring in the tensioner without gutting the whole engine bay?

BTW, aren't gearheads great?

Unfortunately I did not look at the belts and pulleys, just the A/C. Some of the other guys looked at it, though. I think JLAudioEclipse looked at it.

I'd hate to see him change the tensioner and find out it'* something else. I'd love to personally get my hands on that car again. That'* a major undertaking. Anyone else available to poke at it and isolate the belt/tensioner jumping? Or get a stethescope on the car?

I know they decided the coupler in the */C was shot.
