Hi group. I've recently developed a sporadic overheating problem. It may have been around longer, but since it appears to be related to the only recently fixed air conditioning, it's only recently popped up. Most of the time, I'm just fine. If the AC is off, my temperature gauge is solid on the first line above the bottom and does not fluctuate at all. If I turn on the AC, it'll move up above that line just a little, but no more than I would expect with the additional load and heat dissipation. But every now and then, particularly if I've been sitting still, I'll look down and find the gauge has creeped up into the red zone. Here's the funny part, though. If I turn off the AC, the gauge will drop back to normal within seconds. If I turn the AC back on at that point, I'm usually fine again, although after a while (and a few more stops), it may start to creep up again. This car has persistent low voltage at idle problems, but I don't think bad enough to cause enough slowdown of the cooling fans to cause this kind of a problem. I am fairly certain the cooling fans are running when they should be, although since this problem only pops up when the AC is running, I can't easily hear them. I have checked the breaker to make sure it's the upgraded 40 A. I'm going to be replacing my steering rack this weekend, and will check all the usual suspects for cooling problems... thermostat, otterstat, air in the system, etc., but I'd like to know if anyone has any specific ideas, given the apparent relationship to my air conditioning (which is filled with R134a, FWIW). As a side note, #4115 just rolled over 50,000 miles the other day. It actually went over 50K at least a couple of thousand miles ago, because I know the angle drive was broken for its trip here from California, and who knows how much more of its former life, but we'll pretend those miles don't exist. Thanks. -andrew #4115 Houston TX Yahoo!
