No, my mod is not like that. I simply welded the ***** from the ballbearing of the viscous clutch, so you are right, the fan is always locked. I am aware that there is a risk for the fan being locked at high rpm's but it's my only available solution right now. I mean i have no guarantees that the radiator or the water pump is damaged, and they are quite expensive to make experiments.
However, i will try this mod you say about, with my new clutch, the one that is not welded.
The litle incident i reffered to was the sudden rais of the temperature. Before that My gauge never read temps higher than 90 * C even in heavy traffic and with the A/C on.
Thx.

Yes, the radiator and water pump are expensive guesses. How many miles on the current water pump? At some point, it will fail, and it will likely happen at the worst possible time. It might be worth doing it now as preventative maintenance. My water pump locked up at 115,000 miles. Fortunately, I was less than a mile from home and was able to drive the rest of the way before overheating.
I'm all out of help for now. I know you said you read out the coolant temp. from the sender using the climate control diagnostics (and it agreed with the gauge), but I would still be tempted to put a thermocouple sensor in a coolant hose to get an independent reading of the actual coolant temp. Good luck,
Brett

I agree with Brett, when my old car acted like that it was the radiator that had a few tubes partially clogged and that impaired the radiator's efficiency a lot! After I installed a new upgraded radiator, thermostat, coolant pump and coolant temp sensor for the cooling fans the temperature behaved like it should.

loosing coolant
Hi my name is sweat I on a 1992 300se w140 I'm loosing coolant from the back of my block the car has not overheated it has not lost any pressure and it does not burn white smoke my friends say it may be a head gasket but you brought up the T connection what is that and were on the block is it located. If thats the problem I would rather pay to fix that than replace the head gasket.

You need to get someone who knows what they are doing to look at it ASAP. Good luck.

is the T connection related to heater circulation
a small leak in the heater circulation can cause overheating and coolant loss via the reservoir but since dont need heater in tropics we just blocked the flow to heater
also check for leaks in the windshield water reservoir heating tubes showing signs of discoloration of the windshield water
