Heating up on Hills/Steep Inclines
Hey all, took my 220D up some uphill twists and turns and up a big mama hill on the California 62 HWY, I took it nice and slow, even to the point where I had my flashers on but it was still heating up to the white bar before the red. Is this normal?
Once the hill was conquered and it got going to a good speed she cooled down back to normal. It's just the steep climbs that make it heat up. The time before this, I took the same hill on, trying to keep up with traffic and I ended up being just below the red. But this time I took it slow and like I said was on the line before the red. Just wondering if this is normal. Thanks everyone.

Also, I took it up a mountain a few weeks ago at night, and it was pretty steep, and all twisting and turning to the point where I was in 3rd gear the entire time. It didn't heat up and it felt as though it could do that forever. It handled it like a champ although it was 33oF at the point where we decided to go back, don't know if the outside temp was an influence of that.
But these 2 hills, for some reason it always heats up :/

It should not be heating up.i would put a thermostat in it and check the condition of the radiator cap.
ill give you an example. last sunday afternoon my buddy called me to tell me his car has broken down on the highway 30miles out of town. i showed up in the toyota tacoma with a tow strap.i towed his 84 cutlass up the big hills and through the mountains in 3rd gear with the a/c on. the temperature gauge hardly moved. now i take good care of the cooling system, so i dont have problems. my sd used to get a little warm in the mountains.(never in the red) i changed the thermostat and that solved it

The only reason I thought it might be normal was because, with my 300E it would heat up a lot, worried I checked the owners manual and it stated "Engine temperatures might reach the red line in traffic or mountain driving" and was told by forum members on benzworld I think it was that those engines run hot. So I always thought it might have applied for these as well. Since the coolant is pretty new i'll replace the thermostat, you don't have to drain the coolant to do that right?

I would say you might see a few degrees of rise over a steep hill climb but what you saw was too great...a new thermostat should take car of it but if not your radiator might be clogged up and need to be rodded out.

Mine does this too on an entire cooling system (radiator, cap, thermostat, fan and clutch (multiple times), and coolant) that are all within 2-3 years of brand new.

I think it's possible you car is performing normally, depending on the length and steepness of the ill combined with air temperature. My TD does fine under almost all conditions. But if I load it with people, gear, boats and pull a trailer and head west on I-70 on a hot summer day, the temperature guage will climb significantly above its normal range. Driver's manual indicates this is not a problem.
If the temperature was high under normal conditions, I'd be concerned.

I just checked my radiator cap extensively and it has cracks in the gasket, good size ones too. Could this be my culprit?
I got it at a junkyard, probably not the best place lol :S Also I still want to replace the thermostat.
