When you drain a radiator, you still have coolant in the engine block. So if you flush the radiator with water, you will have 70% water and 30% antifreeze when you add a 50/50 mix of antifreeze. Is there a way to get all of the water out of the engine block?
Also, what exactly does a dealer do when they "flush" the cooling system?
Is it better to just drain and refill a system to avoid an improper mix of coolant?
