On the left side of the rad at the bottom theres a large hose that goes into the water pump i believe. Just undo that from the water pump. Much easier.

Mines on the passenger side on the very bottom of the radiator.

Ya by "left" side i meant the passenger side. (left sid when your facing the engine.)
