My car is overheating or is it? Driving down the highway the temperature gauge went from normal to all the way to the top in less then 30 seconds. The coolant light went on and the car went into shutdown mode. My car was running erratic. After reading the manual this is normal when the coolant light goes on (engine safeguard). My coolant is fine. I have no leaks. What could it be? When the car cools off it runs fine.
OVERHEATING ? on 2006 Ford Explorer
if the coolant is good, then there is a circulation problem. possibly the thermostat or clogged radiator. from the sounds of it, you are driving it which means you may have done internal damage from the overheating. have it checked at a shop for the problem and resolution.
