I mentioned this in passing in another article recently, but I thought I'd ask this more directly.
My 1988 Camry has, for at least a year now, been getting very hot when sitting at idle with the A/C on. It can happen on sunny days, it can happen on rainy days. When the car moves forward and maintains a steady speed, the temperature returns to normal, but the brutal stop-and-go traffic that is the hallmark of city driving ensures that I will be standing still for periods of time.
So the question is, where to check first? Is the radiator plugged and not operating efficiently? Does the fan operate at multiple speeds and just isn't notching up? My coolant level is good and at the proper mixture, could my water pump be on its way out?
My workaround has been to cycle the AC off and on, letting the interior fan blow the air around until the engine cools. I can't maintain that indefinitely. Any advice would be appreciated.
