Unusual Radiator Leak

I came home to find a puddle under the passenger side of my F250 with a slight drip originating from the plastic tank seams. The truck had been sitting for a couple of days in the driveway and of course I was getting ready to take it on a 800 mile trip. The next day I added a quart or so of coolant, started and ran it up to temp and there was no leaking. Went on my trip with no issues or leaking. I think this has happened a year or so ago with the same results. I figure it is a temperature differential issue between the coolant and the radiator with the hot days we have here in NC. When the truck is up to running temps things expand and seals any leaks.
Anyone ever experienced a similar leak?
I purchased a Motorcraft radiator from Rock Auto and I am wondering whether to keep it or return, it was handled pretty rough in transit. It could be a couple years before my radiator finally blows up and it would be just my luck to install the radiator I purchased and find it has a leak and it is out of warranty.

If i was in your position I’d replace the radiator now. Maybe not with the one you mentioned that was handled roughly if there’s damage to it, but I’d definitely replace it. They can go from “leaks only when it cools down” to a downpour really quickly.

I've seen a radiator blow in front of me once (it was a TVR) and I'm not sure how the driver controlled it through the cloud of steam. He couldn't see a thing. Not something you want to happen on a steep climb
