Back to this over-heating thing, I am still a little concerned/confused. Ever since I have my car, the temp always read between 95F-100F. Even in winter. I posted a couple questions before, and most advise I got was to try using Water Wetter and had the fan checked. My fan was indeed broken, and it was fixed. I put Water Wetter in my car as advised. My temp still reads 95-100. No change. Called the dealer, and they said its normal operating temp. However, my 98 ML320 always reads 80F. My friend's C280 reads 80F. Is there a range of "normal/acceptable" operating temp? If you think mine is also running too high, what should I do next? Mine is 95 R129. All suggestions are greatly appreciated.
