You definately do have to loosen the small hose on the top right side of the radiator to bleed the radiator. Just be VERY GENTLE with it. If you still have the origional radiator with the plastic tank the nipple is VERY EASY to break off. I have not installed the "auto bleeder" kit. I feel if you have a tight system and have it bled correctly then it is not necessary. Just another hose and connection that can leak. I have a metal bottle AND a coolant overflow bottle so there is no air in my cooling system. I do not have to keep the header bottle 1/2 full to allow for expansion, the overflow goes into the overflow bottle and when the motor cools off it is drawn back in. Another bonus is I can check my coolant level at a glance even when hot.
