Hi, Just curious what the normal operating coolant temp should be on a SLK55. I recently purchased it but we haven't had too many hot days. Today was close to 80 and it was running around 112C which seems high and it smells like its running hot. I wasn't pushing it either just normal driving. I cant seem to find a "normal operating temp" in the manual.

Good question so maybe I was looking at the oil temp on the display which has the little thermometer in the oil can. It was running 112C. I assume there a display for coolant temp.

yes, check that thing called a, oh what's it called? oh yes, the owner's manual :D :D :D

112 might be a little high based on your outside temp also

Well we purchased it from a MB dealer a week ago who assure me all fluids were replaced during their "inspections". But who knows, maybe I should change it myself then I'll know for sure.
