Hey guys!! I have a 2000 Mitsubishi Eclipse GT. The car used to overheat a lot not to the highest point cause I would catch it on time to prevent it from getting there. I changed the radiator, also changed the head gaskets and all the related items. I've been using the car fine ever since but for some reason no matter how much coolant/water mix I add into the cooling system, the engine seems to kick it back out after some time. If I am not monitoring the water reserve of the car, the car can easily overheat. I noticed that a couple of days ago when I got back from a trip and drove my car for about an hour. The engine was throwing hot vapor out on the reserve tank. I guessed it had no water so I started adding water until it cooled down slowly and the engine went back to normal temperature. I don't understand why the engine is not working well. The water that the engine kicked back seemed dirty (brownish color) and now that I filled it up again it's starting to behave like that again. Please let me know what I could do to find out the problem since the car works fine besides that issue and I really want to get it fixed as soon as possible.
Regards,
Teo
