A quick question!!! Is the engine temperature too high that will shut down the whole A/C system automatically??? My 87 190E seems A/C system shut down automatically when the temp gauge over 110 degree.

Also, when traffic jam, the temp gauge level almost hit at the top, but no overheat light on!!! After the car moving, the temp will down to 85 to 90!!! I changed coolant, waterpump, radiator already!!! Do other members 190E are the same or just my car like that???
