300D 124 kinda running hot

[francis]

I have an 85' 124 300D (603 engine). I'm running kinda hot on the slightest stop and go traffic. When normal driving I get about 95-100 and the moment I come to a stop-n-go traffic it goes up to 105-110. The strange part is that when I rev the engine - the temp goes back to 95-100.

What could be wrong here? Here's what I have already done:

1) Replace Radiator
2) Replace water pump
3) Replace viscous clutch
3) replave T-stat (85 degrees)
4) clean/flush cooling system
5) put 50/50 coolant mix
6) AC/AUX fan OK both low and high speed

Did I miss on anything? Some say it could be engine timing.
