So in my super hectic life I tried to carve out a few minutes to do something somewhat relaxing, like topping off the fluids in my 2003 X5. However I learned a good lesson, never half-ass anything on your car... I checked the dipstick then proceeded to pour oil into the tank for the coolant ( Yes I know...) without thoroughly thinking through my actions.

Now to get to the question. I know I have to flush my radiator but could someone give me instructions on how to bleed the tank. I know on the newer X5 models there is an electronic pump, but i don't believe there is on pre-2006. Any help on draining the tank would be most appreciated, i am under the impression from the person helping me (who is far more skilled) that this is not the most complicated procedure, however i just want to gather as much information as i can.

Thank you all,
