Radiator flush

[jalews]

I have flushed my car radiator before. However I have not been able to drain the coolant from the reservoir? How do you go about doing this?

[rivolette]

I'd put a water hose into the reservoir and crank the water pressure up all the way until it forces all the coolant to go into the radiator itself through the overflow hose. (make sure the radiator cap is open when you do this)

Then when the water starts running clear, you can go ahead and fluch your radiator as usual.
