Today I stopped at the local Porsche dealer to drool over a 911 turbo I've been dreaming of. I let my 86 944 idle for about 5 minutes while I waslooking at it, and when I came back the water temperature gauge was well into the red sector with the dash warning light on. Now sometimes when I pull up to a red-light the car will heat up a little but drop down as soon as I drive away, but nothing like this. I put the car in gear and drove away and instantly the water temperature dropped right back down to the normal range first hash mark. The car has less than 500 miles on a new water pump and thermostat. When I had this done the shop also replaced a lower radiator hose and had to fill it back up with coolant. Do you think they didn't bleed the system properly? What else could cause this to happen? I've never seen it heat up into the red zone before, hope it didn't do any damage.
