Drain the water and put antifreeze in the pipes
How do you know it is "Contaminated". You can't decontaminate antifreeze simply drain and then flush the system, then drain and rinse and drain again, then fill to the correct mixture ratio. Hope This Helps.
remove bottom radiator hose to drain system. flush system a few time before adding antifreeze.
1) Take the cap off the radiator.2) Look for a stopcock at the bottom of the radiator. Open it. The coolant will drain out.3) Close the drain.4) Fill the radiator as full as you can.5) Replace the radiator cap.6) Start the motor7) Top-off the resevior as needed. The system will drain the resevior as the motor refills.Don't leave the system dry or the gasgets and rubber seals will dry up and go bad. You do _not_ want that.
I would guess about $100. Drain pipes and holding tank open well pipe to drain that antifreeze in the drain traps
at the bottom of the radiator there is a plug. just twist it out to release the fluid
It should be on the lowest run of piping on one of the downstairs radiators. Or you can just drain the system from one of the downstairs valves (carefully). Or it might be behind the fridge, that's where I found my tape measure.

To change the antifreeze on a Mercedes, locate the drain plug on the bottom of the radiator. Drain the fluid into a pan and refill it.
The answer is no. any regular or universal antifreeze will gum up and ruin your entire cooling system when it is mixed with dexcool. If you want to use any green coolant you will need to drain and flush your your system first.
Yes, simply drain some of the water from the system. Usual way is from the drain valve at bottom of most rads.
