난이도 & 준비물

증상

I have a Mitsubishi Galant 2003, 2.4L engine with 234k miles on it. When I drive it the temperature gauge gets up to exactly midway, until exactly 30 minutes. Then it goes up to about 2/3 or 3/4 of the way up and then fluctuates between that point and midway after that. What started all this was that I was seeing the temperature gauge going up and found a small radiator leak and small leaks in my radiator hoses. So I replaced the radiator, coolant temperature sensor, radiator hoses, and the thermostat. Ever since I've had the car (I got it with 48k on it) I've never seen the temperature gauge

After thinking on this one I remembered when I had a Mazda 323 that would just die if I ran it at 60 mph or higher for about 30 minutes. It was a module in the distributor that was going out. So I went and bought a new radiator fan with a controller and I thought that it resolved the issue, which was a fan controller that was going bad, but was still showing it was within specs with my limited testing tools. It helped some, but it wasn't the total solution. I neglected to change out both radiator fans and the second fan was the intermittant issue. When the car started to overheat, I pulled over and actually saw the second fan start slowing down. With the high mileage and things in pairs seem to go out together on cars, at least in my experience, I should have replaced both fans at the same time. The new second fan totally fixed the problem. One other item I wanted to add, the quality of thermostats seems to be much less to me over the last 5 years. I replaced 3 on two different cars fr
