Need Help, Overheating Problems

mrnickleye · 12-18-2005, 09:58 PM

I will throw this out as I think of it. Mine turned out to be a TINY pinhole leak in the head gasket. It would pressurize my cooling system, but never sucked coolant into the cylinder.

I have seen some water pump impellors that were broken, so it wouldn't push enough water. And the piece blocked off the passage.

If the car will quickly accelerate to 80mph, and drive it steady for a little while (5 min), then the exhaust is OK.

Perhaps air in the system? Gurggling in the heater core???

When you start the car cold, Does the upper radiator hose get hard in a short amount of time without actually driving the car.??? It should NOT get hard until you drive the car for awhile.

Wire your fan to stay on all the time and see if it still gets hot.

New radiator cap??? Does coolant boil over to the bottle??
