Modern systems rely on it. Drag race motors need it. The tech guy at the track gets real testy when he has to clean up your "Burps"...

I recently modified 66 GMC truck to recover coolant in order to minimize oxidation and acid formation inside coolant system.

With high cooling system temps and a high pressure cap, you need to have somewhere for the anti-freeze to go as the engine heats up. The recovery tanks allows it to expand into the tank when hot, and then be drawn back into the radiator as it cools. Without the tank you will just push coolant out on the ground, and you will need to add coolant back in when the engine cools. If you have no recovery tank and don't check the coolant frequently, you will probably end up overheating the engine from low coolant.

Can do help

Old style radiators had a large top tank and space for expansion and you left a 1 in air space at the top. .When detroit changed to cross flow radiators the expansion area no longer existed and an overflow-expansion tank is required. also on a lot of cars the heater core and hoses are higher than the colant filler so you need a tank so when the system burpes out the air coolant can replace the air.

Different types of cans

What is the difference between "Recirculating catch can", "Catch can", "Expansion tank", "Overflow can","Overflow tank", "Recirculating/overflow catch can"???. All of these are listed in Summit. I will have a 383 in a 50 chevy pickup. What is needed?

My coolant recovery overflow expansion tank has an internal vent tube that extends almost to top of recovery tank. Coolant is never lost, just goes from radiator to recovery tank, recovery tank to radiator, repeat.
