Hi, I'm new to the forums and need help. I am borrowing my dad's 86 mr2 and it has an overheating problem. Here are the symptoms: When I drive on the freeway, it starts to overheat when I hit the accelerater. Like when I'm going 65 and decide to pass someone up, the temp gauge reaches towards the red area (but doesnt hit red). But as soon as I let off the accerater and the car slows back down to 60ish, the temp would be fine. The next problem is when i'm at a stop light, the gauge will gradually get towards the red. As soon as I start moving, the temp would go back down to normal. This stopping at the light business happens every single time. So when I park, I pop the hood to look at the engine and see that the small fan on the passenger side is not moving..? So I turn off the car and inspect the radiator resevoir thing to check the fluid. The fluid is up to the top! I know this cant be good but I know this isnt the main problem. I didnt check the front radiator fans, but I dont think those are on either (I will check later tonight to see if those are running or not). The last symptom I notice is that, when I turn on the heater to let out the hot air, it doesnt blow ANY hot air whatsoever (maybe this is the key to the problem?). Does anyone know what the problem is, and can anyone guide me to fix this?
