RE: C280 overheating
Hi,
I have a 1994 C280. I would begin by replacing the thermostat and radiator cap. If that doesn't help, replace the aux. fan sensors. There's one on the engine block near the PowerSteering unit, and another one near the radiator. The sensors are relatively inexpensive and so is the thermostat and cap. I've had to replace the cap and thermostat twice since I've had my car. I bought it in 2000 with 55K miles on it; now I have 170K.
