Hi...

The engine temp. gauge for my W124 93 E320 had been giving incorrect readings for more than 3 months. According to the gauge the engine temperature would never cross the 50 mark, even when it is summer and the external temp. would top 40 Celsius.

Last week I took the car to the mechanic and replaced the part shown in the
pictures (sorry for the quality). The image called 'main' shows the actual part
and the image called 'big' shows the location of the part to the engine. I really do not know the name of this part since I'm new to this, but I am learning.

The gauge started to give more realistic readings but I noticed that the engine temperature is now higher than what it used to be. I remeber that the highest temp. that the guage recorded when I got the car was between 80 -85, and that was in mid summer with A/C on and the car still.
But now after I fixed the guage the reading would easily top 85 with no A/C on and while the car is moving. It is still not summer and yet the reading is high. I suspect the copper washer that came with this part I got. I think it is giving the extra heaT. I checked the oil, water and the radiator has been changed less than 2 years ago.

Any suggestions, help will be appreciated. I wonder if there are any links where I can educate myself more about engine part names.

Thanks
