I don't get the overflow tank actually. I got one from RCI which was $20.

It has a fitting on the top for the coolant line from the thermostat housing. And then at the bottom just has a screw type bleeder valve just like the one on my fluidyne radiator. And that's all there is to it. I don't see anywhere for it to get air into the system.

Anyrate I guess I don't know the theory of the overflow canister to know exactly how it works in the system. I understand the radiator cap, and understand that the coolant overflow both sucks in coolant as well as puts coolant back in when needed.

Will this new one do the same? I'm guessing it will. and that the dump tube is just used for when you overflow the canister.
