2016 Toyota RAV4 Coolant Replacement using OEM Tools AIRVAC Coolant Refiller

OEM Tools AIRVAC Cooling System Refiller. Model # 24444. They are not a sponsor.
Some manufacturers have systems that are difficult to bleed the air out of the cooling system and recommend using such a device. This particular model was pretty easy to fill without encountering air bubbles. I bought this tool to change the coolant on a 2007 Prius which I understand is harder to eliminate air bubbles.

How many gallons of antifreeze do you put in when it’s completely drained?

About 1-1/2 gallons.
