Replaced radiator on 2012 Outback.  Continued to overheat.  Replaced thermostat twice.  Both radiator and thermostat are factory.  Appears to be air locked but all attempts to bleed have been useless.
Thoughts?  Many thanks!  Tim.

Remove cap from overflow tank fill with antifreeze to full mark leave cap off and start vehicle and let idle you will notice level in tank start to rise this is normal once thermostat starts to open level in tank will drop add more antifreeze to full mark then put cap back on.

Park it facing up hill on a decent slope which will help to purge the air.
