Can you run you’re A/C on a long climb? (turbo car)
Posted 15 July 2004 - 11:31 AM
My RX is running hotter than I think it should and I can’t run the A/C pulling the pass (several miles in boost) without it getting uncomfortably high on the temp gauge, am I expecting to much?
Background: ’87 RX, all stock, newer 2-core rad and water pump (changed by PO). I drive 175 miles a day back and forth over Snoqualmie pass. Flat running with no A/C the gauge reads just below upto ½, with A/C on it reads just above ½. Long climb (boosting) gauge reads as high as ¾, climb with A/C = way to close to red. I haven’t verified the gauge with a thermometer yet but my “experience-o-meter” tells me its pretty close.
New rad cap made no difference, so I pulled the thermostat last night and tested it, seemed late to open and never opened fully, even at rapid boil. On the drive in this morning without the thermostat, all seemed the same (I was expecting lower temp), the drive home in the heat (suppose to be 90ish) will show for sure.
I guess my question is wether the stock cooling system is really this marginal or should I be looking for a problem? I’ve got a few ideas on how to increase cooling but I don’t want to band-aid something that should be fixed.
Thought and experiences?

If it helps any, mine gets pretty warm on long pulls with the AC on as well.. probably doesn't help that I have an old ass single core radiator though.
