once its not hydraulic the higher level air pockets might be difficult to get out ... what with all those strength ribs so no path is smooth wall ... and those darn pockets may cause hot spots which means localized annealing and then differential material stress etc etc etc
the vacuum extract and refill would be the safest way
kits are not too expensive mine was like around 85 yankie dollars ... cute process ... :cool:
 
compressors are pretty cheap ... good for tires, blowing off water from the nooks and crannies after wash ... cleaning parts ...
and you get to vacuum drain your coolant to boot :cool:
dont think anything gets yanked off ... just attach the adapter to the expansion tank and go to town
