Have you done a rebuild? Is this why your trying to purge the cooling system? Typically you will need to run the vehicle till the temp gauges reads near overheating, then allow the vehicle to nearly cool and remove the radiator cap. This allows air pockets to be pushed through the system. You can also run it to normal operating temperature and slowly crack the radiator cap allowing the system to expell excess pressure.
