Any definitive how-to's on complete coolant flush/refill using vacuum refill device?

Noop it only take 45 min approx to do both just standing here 60 dollars richer without the toy . The steps you think they're not showing you when you hook up the vacuum line and the nonsense and start the business you'll see why they didn't bother showing you that because well. It's just one of those things people do when they're filming things. The inverters to 3 minute job you won't need anything gravity does all the work for the most part literally. I've never seen that messed up unless they had a hose disconnected for some reason

 

I posted this. Worked perfect, without any trapped air drama.

I have the UView.

The unit works perfectly on the radiator cooling system.

The inverter cooling system is simple. It is a simple straightforward drain and fill. No need to use any vacuum refill system.

One thing I did was to replace the stiff vinyl coil set hose that kept on leaving the intake and allowing air to ruin the fill with ultraflexible silicone hoses.
