How can a crack appear on top of the radiator on a 2007 sport trac? on 2007 Ford Explorer Sport Trac

I noticed a drip on my driveway and could not figure out where it was coming from. Had it checked at they found the crack. The radiator appears to be made out of hard plastic. Can the radiator be replaced with stronger material or do I need to replace it with the same plastic?

thats not uncommon these days,they may have a alum replacement but unlikely
That's how they're made, maybe check with a radiator shop and see if it's cheaper to just have the tank(plastic) replaced.
