Exactly the same thing here, overheats when idling, cools down when accelerate. Noticed when black smoke started coming from under the hood while picking my son up from school. The coolant container got so hot it blew the lid off and all the coolant needed up on the ground. Melted some plastic around the battery casing. I turned off the ignition just in time. Towed it to a shop, they replaced the fans and thermostat, seemed to be ok for a week or so. The problem has returned, but now AC is blowing hot air too. Checked everything else for damages, leaks, malfunctioning, everything is in great condition. Now even a quick drive-through or an idle at the red light are enough to overheat the engine.
Cool while driving but overheats when in traffic or sitting at red lights.
My radiator was leaking so go get a new radiator ..then thermostat .was suppose to be the problem but car stills runs hot ... the dealership charged me$261.45 and tell me I am to pay $123.34 to look at the car more...
Radiator blew because of overheating; coolant level was fine, but fans failed to cool engine even after cutting ignition
Still arguing with Mitsubishi to get to the bottom of it
Replaced controller still seems to go up high
Same thing happened to me @ 120,000 mi
engine temp surges when Idling then cools off when accelerate
Sometimes overheats when stopped in traffic. Goes away once I start driving again
New cooling fan installed
Only on hot days above 75 degrees or so. Engine temp climbs rapidly while car is idle after being used.
Car overheats in the warmer months when idling. Once, I start moving again the car returns to normal.
Over heats and the air conditioning light goes on when I turn on the heat
Did the recall and honestly I didn't check to see if the fans worked afterwords, but did notice A/C still didn't blow cold, wasn't big deal was winter time anyways. My radiator blew and I'm finding myself having to change it and thermostat "better safe than sorry", as I may as well since I'll have it all torn down. Heading back to dealer to question the change in controller, due to recall. This is getting a bit tiresome and expensive.
I had to have a total engine over haul and still after I have the same problem. What do I do?
