Thermostat Bypass

Set the bucket on the floor by the engine, that's where the return goes (old liquid) and put the hose with fresh water/coolant on the upper step above the engine, that way it's fed by gravity. I've also used a funnel on the upper hose and just poured it in instead of relying on the engine creating a vacuum.

It sounds to me like this method would avoid any air bubbles, and the need to burp the system. Did you find that to be the case?

Indeed, it's quick and what I like best is that it's quite thorough. I flush until I see a consistent stream of clean water and then a consistent colour of antifreeze. Helps to have a second person present to either hold something or swap buckets as it gets full.
