I have noticed that since I replaced radiator, water pump, hose, blah blah blah that my XJ runs about 210 all the time, with one exception.
Anytime I drive 70 to 80 mph during a 95 to 100 degree day, the temp will rise to 225 degrees (first hash mark past 210) and stay there until my speed drops to 50 mph or lower, then it will drop fairly close to the 210 mark again.
If it is cooler outside, like it was yesterday evening when we came home, the temp will go mid way between 210 and 225. As an experiment I turned off the A/C and after a couple of minutes, the temp dropped to just above 210.
I've read here before about the A/C causing the cooling system to heat up, but I do not remember if there is something I can do about it. A/C under charge, over charged?
Maybe it isn't the A/C, maybe the transmission is slipping, or the CAT is blocked. The torque converter unlocks if I tap on the brake (I see the rpms go up then back down).
