Hi, I am having the same issue with a 2002 Mitsubishi Montero. The SUV used to be the most reliable vehicle I owned. New factory-spec radiator, flush, oil change (full), new water-pump, timing (the whole front-end kit). Engine service light is on and was for 25,000 miles before this issue started. No coolant in plugs. SUV accelerates fine, no hesitation or stalling. Issue is overheating when driving at any speed for more than 10-20 miles. Idles cool and heater no longer blows hot air. The SUV is overheating as the AC blows hot air when the needle reaches critical temps, e.G. Not a sensor. No smoke in exhaust. I am not in a position financially to buy another car so working to solve this. Solutions?
