I’m not sure what you are doing to get air in after filling it under vacuum, we do this just about every day and have never had an issue with trapped air or having to top up a system that tested leak tight before filling. Do you let the Uview pull in the coolant mix until it stops (the vacuum goes to zero), at which point the fluid level in the tank is usually at mid level? We have had cars come back to the shop for other service months after the coolant was changed, and the level in the tank was just fine without any top ups……….
