Thought I put this out to the group for discussion. My 2000 CLK 320 has been running a bit hotter than normal lately (A tad above center). The usual suspect is obviously the thermostat (w/housing) yet to be changed, however, the only theromstat available for these cars is an 87 degree option, no others. Furthermore, I didn't find anywhere where the aux fan may have a sensor which would be the other usual suspect, at least on my SL. Any input or comments?
