Here is a little more clarification on my car's operating temperature. Prior to the new water pump and antifreeze change, the car ran at just over 80C most of the time, including summer (HOT in Dallas ambient temperatures). The RARE exception was stop and go traffic where I would see temperatures approaching 90-95C in the dog days of August.
Now, I see 90C almost all the time. The ambient temperature since the waterpump and antifreeze was replaced has not been over 50F. I am almost sure that with warm/hot weather, the operating temperature will be above 90C, which I consider totally unacceptable. I must mention that at highway speeds in this cooler weather we are having now, the operating temperature drops to a normal 80C.
Thanks for your interest!
