Hey guys, I just purchased the c63 amg yesterday and its my first performance car. I had a quick question about the engine temp. For daily driving is the engine temp supposed to be around 90 degrees C.
For some reason I always think the engine is overheating. Sorry for the retarded question...

Seems normal.

Don't worry our cars run hot. Touch the fenders or open the hood after a long drive or hard session.

Sincity

For that I wish we had vented hoods.

Everyday driving my oil temp is around 90C, if I push it, it goes up to 105C.

I see 117C on a reguar basis and have seen 127 on the tack.

thanks for the replies

Ditto for me to, city and track are the same as what you experienced.

u have to know, we have limited engine room, but with that size engine, there is not much room left, which means the car have limited capability to cool down the heat...it is very normal to have a bit higher temp than other performance car. Besides, 90 c is about rite...mine R34 before also 90 C when i was crusing...

92c engine temp normally, 100-105 engine oil temp. if im hammering it goes up quick to 115c oil temp

i didn't wanna make a thread about this , i searched and came up across this
but i got a quick question if anyone's willing to answer, i just purchased 02 clk430, and also im a new member here, when i drive my temp sits around 80, but when the car is stopped for about ten minutes it goes up there in the 90,and 100 if it really sits for long...is that normal? again sorry for the question, its my first mercedes, im not really familiar with these cars that much, but i sure love it so far.. thanks guys

Not too sure how the clk engine runs. Not sure how hot it's suppose to be. Did a quick search and found this for you. https://mbworld.org/forums/clk-class...long-time.html
If that doesn't help, cuz I read through it and it didn't show any numbers, I would advise asking them since they have had the cars for a while

tikiferrari

thanks appriciate it

depends on the climate you live in as well

what i noticed though is even though the engine is pretty hot theres no cooling issues even after a hard track day. At the track the engine temperature is very consistant at around 120

reco

I am not an mechanic. I had similar problems in the past with 240D, 230E, C230 and C36amg.
simptoms- temp gauge going over the top part of the nr 8 from 80degC till 100-110degC (at very slow driving or waiting with engine on). usually it is a summer issue, no problem over 40-50 km/hr or in the winter or when AC it is on hot/red.
reason- faulty the sensor which turns on the fan/fans in the front of the radiator. quick fix (just to keep you moving safe) -keep open AC fan on at least 2 on warm/hot or cut the wires before the sensor and join them together. the fan will go all the time regardless the engine temp till you'll find a specialised garage to get a new sensor.

reco

if is not the sensor means it is the clutch bearing which is holding the fan.

Does anyone know of a reasonably priced, cooler thermostat for the C63?

It may be necessary here in Vegas to keep the temps low from the start. With this kind of heat, once it's too late, it takes a really good cooling system to recover from 120+ degrees in summer heat.

Well MHP and Evosport both have their products. Forgot what it was called thermostat something. They both claim to lower temperatures, and I think MHP was claiming about 10 degrees on avg. The cost of it was I think a few hundred for the part. Dunno how much installation would cost though.

Vegas_AMG_C63

Typically thermostats are $15 parts... maybe, I'll pull it out myself and cross reference the thing. I'm sure that's all they did!

Even to have the stock one modified wouldn't take much. It's a coil that heats up to a specific temperature and applies pressure to the valve to control the flow of water... This isn't that difficult of a part. I was just hoping that someone may have already figured this one out. http://www.trustmymechanic.com/parts...thermostat.htm

Don't get me wrong, I'm all for supporting the sponsors of this forum with their quality technical parts that make our cars go fast. But $200+ for a thermostat! There's got to be some justice somewhere.
