| 2000 E46 Overheating
My girlfriends 2000 328ci expansion tank exploded, so I replaced it and filled the coolant back to proprer levels. I did my best to get the air out of the system, but the car still overheats. The car seems to only overheat when driving. I let it idle for 10 minutes and it was fine, but less than a mile driving at 30 mph and it went to red. I noticed that the radiator fan is not coming on even when the A/C is on. Radiator is only a year old and system doesn't have any leaks. So my questions are...
How do I test the water pump?
How do I test the fan?
What is the best way to get air out of the system?
And what other issues could be causing this?
Thanks for all the help...I'm new to fixing Bimmers! |
