I was climbing up a long (3+ miles) steep grade at about 70 mph in 90-degree weather this afternoon and watched as the temperature gauge on my 1988 9000 Turbo climbed up past the 3/4 mark to almost the 7/8 mark about two miles into the climb. The turbo needle was pretty far into the yellow, so I know the engine was working fairly hard. I chickened out and turned off the a/c and was getting ready to open the windows and turn on the heat, but the coolant temp didn't climb any higher. No apparent damage done, but I wonder just how hot these engines typically run under these conditions and when should one start worrying/taking corrective measures. FWIW, the car is an automatic with 136K miles on it. Other than the temps, it drove great. Even on flat ground in warm weather the needle will move between the half-way and 3/4 mark depending on ambient temp and traffic. Today was the highest I'd seen it go. I have another trip over the same route in two weeks, so I have time to choose our other car or try to fix the 9K if it needs it. Many thanks.
