First drain the unit, then fill the cooling system with water. Turn engine and let it run until it warms up really good. Drain the water and re-fill system with anti-freeze mixed no stronger then 50/50 mix of your chose.

You may need to fill, run and drain more than once to get all of the old stuff out. Repeat until what you drain has no color at all.

When you refill, it is best if you use distilled water rather than tap water. That keeps the minerals out of the system at the start.
