It's under warranty. Replace it. If the stop leak doesn't work, then
you've given the shop a reason to void the warranty and you'll have to buy
yourself another radiator. The stop leak stuff isn't a great idea to use.
If it doesn't stop the leak in your radiator it will eventually find some
place to solidify and whether it's in the radiator or engine, it's blocking
flow either way.
