Radiator overflow question. - The 1947 - Present Chevrolet & GMC Truck Message Board Network

So I'm going to use the radiator from the donor vehicle (08 escalade 6.2) in my 72 burb. There is no cap on the radiator like my old radiator. Do I need to run the overflow unit from the donor vehicle? Does it have a special pressurized cap on it? Can I use any overflow container with a lid, or does it have to withstand great pressure?
Are these new cooling systems not pressurized?
Thanks in advance!!

The overflow tank from a 99-up is needed if using the donor radiator.
