[59 wagon man]

i need to vacuum down the coolant system to make my hemi bleedd out the air trapped in the coolant system. any ideas?

I use an airlift kit, works great but for a Diy you could probably use a mighty vac vacuum bleeder, buy a spare radiator or degas cap drill a hole in it and put one of the tips in it with epoxy. Not sure if that method would work but if you have a vacuum pump at your disposal buying a spare cap may be the cheapest route.
