Thank you for the question and replys. I have had a question bugging me now for several weeks, regarding my cooling system. I have a 95 ETC with less than 70K miles. I am really enjoying the car. However my coolant temp will fluctuate from 179 to 235 with little provocation, (well climbing a 4200 ft. pass with the ambient temp about 90 degrees, A/C running). As soon as I drop over the top of the pass, and take the load off, the temp comes right down to 180-190. 235 degrees seems too hot to me, but after coming to know the high speed of the fans doesn't kick in until 236, I guess I am just over reacting. If I was reading a dummied down analog gauge, I probably would not even notice the wide temperature variations. (Well I probably would). I have noticed that ambient temperature, makes a big difference in how my cooling system responds. Does this all sound normal? I suppose I could just hit the "display off" button??
