Look for the petcock on the side of the driverside radiator tank or the very bottom of the tank.
Removing the lower hose is a quicker method for most people.
There are also drain plugs on the side of the block. Typically they have a square hex on the head.
Remove & clean out the over flow bottle too.
Good Luck.
