Not sure how to bleed sealed system?

Recently adjusted weak coolant mixture by removing lower hose from expansion tank, draining off about 1L from expansion bottle & adding 1L of ethylene glycol anti-freeze.

Left yellow pressure cap off while I warmed up the engine, purging bottom rad hose until it got nice & hot, then replaced pressure cap with engine running until it reached operating temp & fan kicked in.

Is that good enough or is there a proper way to bleed the system?

Thanks :thumbs_up:
