Jim, I first noticed it when the temperature climbed a little during the summer. As I said above, never over 100, but not the absolute rock steady 80 that it has always been. I checked it by opening the hood and watching it as I shut the engine down while the water temp was 100*C and ambient was 90*F. It kept spinning like crazy after the engine stopped, so I knew it was out of fluid.

There was also a nasty black gunk all over the fan blades which I assume was the fluid combined with dirt.

I could also spin it freely when the engine was dead cold, which you should not be able to do. The fluid settles in the bottom, and locks the hub when it has been sitting a while. Then on engine startup the centrifugal force distributes the fluid and it unlocks after a few seconds.

pberku - it is the original clutch that came from the factory. I've owned this car since brand spanking new. 109,000 miles on it now.
