I have a 1990 325I BMW and its overheating. I've changed the thermostat, the hoses, the radiator cap, the water pump and belts, and fan clutch and it's still overheating. I can drive on the freeway with no problems of overheating. But as soon as I get into town, its all bad. It starts getiing hot. I can't figure out what the heck the problem is. Can you?
Flush Your Radiator
Have you ever replaced your fan motor? if no, have it replaced.. if yes, you probably need to replace your radiator. try to get those after market aluminum radiators. This will give your car better cooling.
Its also possible that your car's alternator is not at its best anymore thus giving low amperage to your fan motor and other electrical devices. this will slow down the RPM for your fan. This will cause your engine to overheat due to insufficient cooling.
