Coolant Venting Issue
I'm a new member and not sure where to exactly ask this question. I just did a radiator drain and refill based on the DIY write up. The issue I'm having is that I cannot get the water pump to vent. I put the key in hit the ignition button(with foot off the brake) set the heater to max(84 degrees) on the lowest fan setting than push the accelerator to the floor for 10 sec, but nothing happens. All i hear is the air coming from the vent. I get under the car and listen to the water pump and hear nothing. Anybody have any ideas or suggestion on what I'm doing wrong. I have a 2006 325i if that helps.
