I just had an idea. Could the electromagnetic fan of my car be wired to be permanently on (maybe by previous owner)? This just came to my mind after I viewed a 190e 1.8 for sale on behalf of my kid brother.
The temp sensor (3 pin with 2 pins for connectors) was seen without the connectors. And the car was running without overheating.
Same goes for mine. I drive the car all day with the air-con on and at 32 to 34 deg C outside and the max running temp is around 89 deg C in stop-go traffic. It doesn't overheat.
And mine has been running with the 2 wires disconnected since the burning incident.
I am planning a long drive up to Malaysia soon and this issus gives me no peace of mind...
Another thing, after driving around town for about 45 minutes the other day, i switched off the car and spun the clutch fan. It moved only about 1/4 turn...?????????
Wouldn't that mean the clutch fan was working?
Yikes. This is freakin' me out.....
But it would be fun to solve this...as with the other problems...as it is, I have no tach till this day and that's no fun!!!
