Reply to "Using a vacuum to refill the cooling system. What is the max vacuum, 16#?"

as you vacuum you will eventually see the upper radiator hose collapse. Watch your gauge for maximum vacuum, shut your valve. Walk away and come back in 20 minutes to see if the vacuum is holding.

if it holds, you are good to go, but if not, you will need to track down where your system is not fully sealed
