I´ve tried various ways of burping the system. The quickest, especialy for the intitial run, after cooling system work. Is to start the motor, with the surge tank at least half full, cap on. When the motor gets to operating temp. squeeze the top radiator hose, with both hands at least half a dozen times (vigorously). Add a little coolant and repeat if necessary. Works much of the air, into the surge tank. Add some coolant and let the motor cool down and suck some more coolant into the system. Repeat the next day. This will remove the majority of the air quickly. A few more hot cold cycles will take care of the rest. I usually try to avoid stressing the cooling system with high speed runs, mountains or prolonged idle, until I´m sure most of the air is out of the system, which usually takes a few days.
A footnote, I´ve been reading some threads about flushing the radiator and heater core. Pressure over about 15 PSI in the radiator could cause damage. 30 PSI and something is subject to blow. Most garden hoses put out 90 PSI or more.
