Radiator
Manufacturer warranty
Potentially covered under bumper-to-bumper coverage while active.
Powertrain coverage
Often not included — the radiator is a cooling-system part, and many powertrain definitions stop at the engine itself rather than its supporting cooling hardware.
Exclusionary service contract
Coverage varies by contract; cooling-system components are included in some plans and excluded in others.
Auto insurance
Ordinary mechanical failure, corrosion or leaks are normally not covered by standard auto insurance; collision damage to the radiator may be, as part of that claim.
Manufacturer recall
Only applicable if there's an open recall for a specific radiator or cooling-system defect.

This is general guidance about how these coverage categories typically work, not a diagnosis or a claim about any specific provider, manufacturer or your own contract. Always check your actual warranty booklet or service contract for what's really covered.
