overflow tank boiling over??

[1987E30project]

So as long as the overflow tank is higher than the radiator you should be OK?

no as long as the overflow is higher than the hose going from the overflow to the thermostat housing is gravity fed. it has to be higher than about the middle of the thermostat housing.

not necessarily. I'm running the m20 bottle and have no issues with bleeding. The feed hose is longer than it should be and has an "s" bend in it so the flow isn't optimal. But I use the "blow through the pisser line" method (that sounds dirty) which works quite well.
