Awesome link blackbrick

 

you dont need to take off the belly pan to drain it though...

 

My recommendation is to never try to use the drain on the radiator - it seems to have a 50% failure rate where it breaks and then you need to buy a new radiator.

If I need to drain some coolant I just pop off the lower radiator hose.
