Today I once again confirmed that on highway car can keep 100C, [Da-a new that before!!!]
In slow traffic (city with traffic lights) temperature is jumping around (>100C...)
Interesting fact is that if temp is 110C on traffic light and I put in neutral and send engine to 2500RPM -3000 RPM temperature is rapidly dropping to 100C, if I keep engine at 1200RPM temperature is almost always stays on the same level (with idling speed of 600 RPM after exiting the highway temp is growing).

Since on my way home I have to cross 2 huge bridges (around the mile each one), some more details: bridge on the way up adds the temperature (even though engine is running almost the same RPMs), on the way down reduces the temperature. I think I can understand this fact... but still wanted to share.

Another question.....
I was trying to put everything together in front of me... so I can make some kind of analysis.
Can someone help with temperature measurements?
I have "laser" (IR) temperature measurement tool, however it is useless without knowing the values that are OK for the car.

Can somebody look up the proper (HOT) values for
a) Upper Radiator Hose
b) Radiator (under the main fan)
c) Lower radiator hose
d) Engine Thermostat
e) Water Pump

I will try to get all of my measurements with hot engine and post them here.

Sounds like you have air in the lines. I had this on my 190 and was a ***** to get all out! Need to pinch one line and squeeze another then let off the pinched line! Not sure which in your as I do not know all the hoses on that engine! Also get some Water Wetter!
