o man why does it have to be so simular to my problem? lol About a month ago I bought my first car. An '88 supra with a 7mge engine. anyway it overheated on me on my 2hr drive back home and i(my mechanic, i gave up) found out the radiator wasn't pumping out enough coolant at higher rpms. so I switched out the radiator with a all metal one and changed the clutch fan for added safety. As of now i have no heating problems.
