Yes, I've been doing almost everything everyone has suggested.
- replaced thermostat with new MB thermostat (opens at 84 degrees celcius)
- replaced rad cap with new MB cap from dealer.
- Flushed rad and changed coolant.
- Checked fans. Appear to be working, at least the one that is behind the rad.
- Trying to figure out if the Aux. fan is malfunctioning. Turned on A/C and the fan wasn't spinning.
- Bought a new 100 degree switch today at lunch and will replace that tonight.
- Any new suggestions? Thanks to all....
Brad.
