2000 Cadillac Escalade Radiator

if there is a drain plug it will be on the drivers side and of course at the bottom. they often break though when tried to removed. A better thing is to take the lower radiator hose off so as to get the aluminum out of the system. If you do flush the system by yourself be sure to get a good radiator cleaner and follow the instructions. then replace the new radiator with a good 50/50 anitfreeze mix.
