Idea for cooling system flush - W210
So I have been wanting to flush and fill my cooling system but have been putting it off because of my perceived "hassle factor" of accessing and draining both the radiator and engine block drains. I'm a big guy and the idea of reaching into cramped areas does not appeal to me.
As I was looking under the hood, I noticed the pump for the residual heat system is easily accessible. My possible ideas for alternative ways to flush the system would be 1.) can the coolant lines at the residual heat pump be disconnected and used a block drain alternate? or 2.) can a jumper wire be attached to the residual heat pump and the pump be used to pump out the old coolant?
I am being crazy, lazy or what?
Give me your opinions.
