What is this!!!!??

The kit that comes with should also have another part that fits snugly in your radiator filler opening. It's a tube that directs the flush water up and over the front body when you're reverse flushing your cooling system. Keeps your radiator from looking like a decorative fountain spouting cooling and water all over your engine and body paint.
Another thing I like to do to make sure as much coolant is drained as possible is to replace the square-headed threaded fittings on each side of the block with petcocks.
