I DO crank it up to the full 15 psi. The way I handle the hose is to just loosen it at the radiator, not take it off. Sometimes you have to wiggle or twist it a little to "break it loose" so the air can come out. By going up to 15 psi you compress the air so there is not as much to get out and it comes out faster. You will know when all the air is out and the coolant starts flowing. You will hear the hiss stop and then see the coolant. Just use a shop rag or a paper towel to catch the coolant. You do not have to get every ounce of air out. The radiator does self-bleed a little. That is why there is the venturi effect in the pipe going from the radiator to the coolant bottle. The thermostat housing is a different story. Air will accumulate there. It can accumulate to such a point as to prevent the water pump from circulating the coolant. That is why it is so important to have a "tight" cooling system. A leaky system will draw air in as it cools. This will eventualy cause the system to be "air bound". The self-bleeder kits only deal with the symptom, not the actual cause. If you find that installing a self-bleeder "fixes" an overheat problem you should really fix the leaks which in many cases will be the seals and gaskets under the intake manifold or the 25 year old radiator.
