On my Buick 3.8 I disconnected the lower and upper rad hose and flushed it through with loads of water form the garden hose. I used plumbers pliers to squeeze the clamp. Filled it with water and drove it to the store and back. Flushed it again. It dripped for a good while. I made a 50 50 mix of distilled water and Peak global lifetime. I ditched the Death cool. I had death cool sludge in the over flow bottle. Had to clean it out.

Which Buick is that? There's no way in a million years I could ever fit plumber's pliers down by my lower radiator hose. Matter of fact, when I remove my lower radiator hose, I gotta use the cable tool AND remove the electric fans.

What if the ears are facing up; then what do you do?
