I have a 1991 240 and she has been running hot when sitting in traffic or climbing long steep hills. She also tends to run hot when I run the A/C. She never actually overheats....but the needle on the temperature gauge almost reaches the red each time this occurs. The temp drops again when I start to move again or decend the hills. Could this be a radiator problem? It is the original Rad and the car has 180,000 miles on the clock.
Also, in a totally unrelated issue, she occasionally hesitates when I depress the accelerator to take off. It is very subtle, but it does concern me. I am thinking that I need to replace the fuel filter....but I could be wrong.
Thanks!
