So i just Purchased some OEM bmw coolant and it seems as if there is Green coolant in my Expansion which leads me to believe it is also in my whole system . I'm really confused as to how i can flush it all out and add My Bmw coolant + Distilled water ! Anything helps guys

Remove the black Phillips head radiator drain plug, be sure not to break the hex cap it screws into - it's not meant to twist or come out.

Drain the coolant, pour in distilled water, and bleed the system by holding the gas pedal down. Literally, rinse and repeat until water comes out clear.

yeah flush it...my co worker's mechanic put the cheap autozone green coolant into his vw....it mixed with the oem coolant and turned it into jello and over heated his engine.

Where is the radiator drain plug Located and what about draining from the water pump ?
