Much easier to use pressure.
I put a quickchange fitting on my coolant tank.
hooked it up to my compressor, set at 15 lbs.
I bleed the coolant manifold/hose.
but that was before reversing it.
Dont need to do that now.
2nd, bleed the radiator.
give the bus a rocking motion,
till the bubbles stop.

> Has anyone ever thought of a way to bleed the cooling system on a Vanagon by using a vacuum pump?  Would it be possible to hook up an electric pump of some sort to the bleeder valve on the radiator, turn it on, and then while someone keeps the reservoir topped off, run it until it runs free of bubbles.
