Best way to drain/change the coolant?

Personally, I go for the 'drain it and fill with water' approach - and add some rad flush too.
Run it for 10-15 miles, then drop it all back out and fill with proper coolant.

Its worth noting catch the coolant and dispose of it properly.

Its toxic to cats and dogs and cats will lick it beacuse to them it smells and tastes sweet
