Hi everyone. I just purchased a 2011 E350. I just noticed that the temp gauge is all the way up to the 120c mark. Is this normal is the question. A few other things I noticed is that it kinda twitches and back and forth and then goes up. I am not getting any warning on the dash or anything tho. When I turn the car off the fan runs for about 2-3 minutes afterwards, Is all of this normal and if not what could be the problem so I can try and get the deler to take care of it since I just got it yesterday. Thanks in advance!!

Not normal as most of the engines are design to work in 80-85C range.
Did you check coolant level?

roecityryder

Yes I just topped it off

120c ?? your temp is at red line already. that for sure its not normal.

roecityryder

Yea, but it's not giving me a malfunction warning which is strange.

You don't consider needle in red zone a warning?
Get infra-red thermometer and first confirm it is hot engine, not faulty sensor .

roecityryder

of course I do and I will try that. Maybe the thermostat is stuck. I don't know, I just hope it's nothing major.

Yeah, you need to get on this right away. Usually, when a t-stat fails on these cars it will default to full open and you will get a CEL. The temp will then be BELOW the normal range.

You just bought it and you had to top off the coolant next day? Take it back to dealer and tell them to do atleast an inspection on your new baby.

Update!!! Just got back from an indie shop and it was showing a code of P0485. They said it has something to do with the fan. It was late when I took it to them so I have to go back in the morning to have the actual repairs done. Other than that fault code he said it looked good and that I made a good buy. So I will update u guys tomorrow and thanks for the help.
