Default Radiator Hose Help

This is a pretty general question so anyone can answer, not just those with knowledge of the STi. I just bought Perrin Radiator hoses for my STi and I plan on installing them tomorrow. However, what do I do to get the stock ones off? What I mean is, there is coolant in the hoses, so what do I do about that? Do I just pull it off and drain the fluid into a bucket? Is there a proper way to take them off to put aftermarket hoses on? Thanks for the help.

Theres a drain plug at the bottom of the radiator (passenger side)
After you pull the plug, take the radiator cap off

The drain plug is there for a reason
If you pull the lower hose you will still drain the system
.....but youll have coolant everywhere

Also, Im not sure about the Perrin but some samcos had to be trimmed to sit right, otherwise they rub the alternator pulley

make sure your car is fully cooled down before you open the coolant system.

The hose on the bottom of the radiator is the lowest point in the cooling system. therefor you will have to drain the entire system. there's no way to just drain radiator hoses. Sorry@
