I also have a “recovery reservoir”. It’s an antique freezer jar that is hooked to the radiator overflow and also has an overflow of its own. It does take on coolant and the coolant siphons back in as the system cools.
However, this thread makes me wonder if the excessive puking/low coolant level is a function of the system sucking air somewhere.
In my simple brain, you would need something more than a zero pressure cap for the system to recover coolant from the reservoir. But I also know that the early heater cores do not respond well to pressure. Need some guidance on the right way to approach this problem.
