Hi,
ive been looking around the forum, ive found some posts explaining on how to vent the cooling system when changing however theres no description of where to open to flush the coolant. help!

 

I cant guarantee it since I havent changed my coolant myself yet, but every car I have own in the past has a draincock at the bottom of the radiator. So I am sure that it should be as simple as jacking the car up, removing the underpanel and opening the draincock plug to drain out the fluid. Flushing the car should also be the same as any other flush.

GL...maybe someone else might be able to tell you from exact experience for an e60.
