Benzmac,
Can you describe where the low speed fan resistor is located on a 92 500E? I'd like to check mine for good measure. TIA
Steve,
The temps on my car can see up to 106 after hard driving and or altitude. I've also experienced 110F at plus 4500Ft altitude, 98F and hard driving.
Try changing your coolant ratio to 40% Coolant/60% Water. We don't have problems with freezing in San Diego.
so this will benefit the cooling system. I've found a good synthetic oil also helps keep my car running better.......I know it sounds weird but it's worked.
