Bmw overheating

Asked by Sep 03, 2016 at 05:51 PM about the 2003 BMW 3 Series 325i Sedan RWD

Question type: Maintenance & Repair

I replaced my radiator, thermostat, water
pump, new upper and lower radiator hoses
and new coolant reservoir. It still wants to
overheat when I drive on the interstate and
It's full of coolant and my thermostat opens
up, why am I still having this overheating
problem??

Did you bleed the system properly? Air in the system will cause an overheating issue...https://www.youtube.com/watch?v=mX2EFnAL- Q8

check to see if you have a mechanical or an electric fan and ensure that it is, 1 turning the correct direction and 2 that it turns on when the car reaches operating temperature, if its not you may have an electrical gremlin or your temperature sensor isn't functioning properly

Check your radiator fans as mentioned above.

My fan is turning the proper direction and the sensor seems to b working properly as well as it still sends messages to the computer when the temperature rises. I don't know what the hell it could b!! I've bled it, changed parts, checked the fan and it still overheats!?

Some times the problem is the head gasket. If the problem is not big, you can solve the problem with a liquid that contain little pieces of metal that fill the gap that the head gasket have. I did this solution two times with good results, and one time with no results. The name of the product is bar's leaks,
