I have a potential problem with my 380SE. While it does not overheat, it comes close (in my opinion). The gauge goes 3/4 of the way up (near or slightly over 100*C) in SLOW stop and go city driving. It may not be classified as overheating, but it goes higher than I would like for it to be. On the highway (at speeds over 55), it runs normal. I NEVER have seen or heard that auxiliary fan on. The ONLY time I ever hear the clutch fan is when I first leave of the morning (when the car is cool) and I can hear it ROAR until the car gets to about 40 MPH, then it quietens down. I never hear the fan again, no matter in engine temperature.

I guess I need to check.... 1. clutch fan, 2. aux. fan, 3. change coolant, 4. flush radiator. Oh, BTW, yes, it has the "no-no" green coolant.
