more antifreeze observations/consumption, am i bleeding correctly?
after adding roughly 1.5 cups of water to the rad yesterday, the level with bleeder shut is only about 1 inch above where it was previously. i haven't had a chance to open the bleeder and see where it is, as the car is still hot. is it possible that there just isn't enough water in there? someone care to explain how one is SUPPOSED to bleed? thanks.
How I bled the 525im. By Dave MacIsaac, a rookie:
Take it for what its worth and jump in if you feel inclined. I had just replaced the rad and main rad hoses and filled the system with the blue stuff as best I could with the car relatively flat. I had drilled the small hole at the arrow in the thermo as well.
1) From a 'warm' start (top rad hose warm), I parked the car on a 25-30% slope, wrenched on the park brake and blocked the wheels.
2) Shut the car off, filled the expansion tank almost full started the car again, reved the engine to @ 2000rpm, watched as it sucked coolant from the tank. Continued untill it sucked no more.
3) Cap back on, engine running, open bleed screw and watch it trickle down the side of the expansion tank for a minute or so, until no spurting and spewing of air/coolant is visible and it runs clean (Nissen rad may be different than the Behr). I think I had filled it fairly well before hand as I saw very little air emerge.
Is this what you were looking for? I've never heard the method you cited before, with the drivers side corner raised, pouring coolant into the bleed hole.
