I am new to the MBNZ world. I have a 1991 420sel that I have owned for approximately 3 months. Since weather temperatures here have increased lately (95-105F), I have noticed some strange activity with the heat gauge. Normal operating temp on this car is usually just above the 80 mark on the temp gauge. However, with hotter heat, I have noticed that at slower speeds and when pulling hills with a/c on, the temp is rising about 2 guage needles widths above the guage mark following the 80 mark (I cannot recall if this mark is numbered). Is this normal or should I be concerned?
Any input would be greatly appreciated
