It will work but if it were me, I’d consider it a temporary fix and buy a new radiator because they’re not that expensive.
Keep in mind that if the leak is in the plastic tank of a radiator it’s entirely possible that tiny sealed leak could instantly become a long, gaping crack. Plastic can work great until it gets some age and heating/cooling cycles on it.
You can probably get a brand new radiator for about a 100-125 bucks. Compare that to the cost of an SHO engine.
