: This AM, I took a screwdriver with me on the way to work, the idea being that if it started overheating, I could pull off a side-street and bleed the system. Well, all was fine until the final 1/2 mile where there was no way to get off the road. Less than a minute later, the temp dropped to normal and stayed there. After parking, I popped the hood and checked the bleeder... it bled fluid. GRrrrrrR!
: So, any idea what the deal is?
SOunds to me like you have a sticking thermostat. I've seen that same type of overheat/cool scenario with other cars and it was nearly always the thermostat or the radiator cap.
