'89 overheating

SlaytanicScotsman · 06-10-2005, 12:41 AM

Hi,

I just bought an '89 Supra a couple months ago. The previous owner claimed to have flushed the cooling system. It runs completely fine around town and on the freeway UNTIL I reach stop and go traffic on the freeway. It then begins to overheat, and I have to blast the heater until I can get off (and in 90 degree California weather this is not pleasant!).

When I stop and open the hood after this, the coolant reservoir is jiggling like crazy and spews out coolant from a horizontal black tube that's on the top of it.

I am constantly checking to make sure the radiator and coolant reservoir are full, and I don't know what's causing this problem.

If anyone could suggest any and all possible causes, I would greatly appreciate it.

Thanks,

James
