Will this radiator work with my existing cooling system components?

Yes — this is a direct replacement designed for factory mounting. Your existing hoses and thermostat housing connect without modification. If your current radiator uses a transmission cooler, confirm the core has matching ports before ordering.

Does this come with a cap, petcock, or drain plug?

The radiator assembly ships as the core unit. Verify your current cap and drain components are reusable before installation — if either is damaged or missing, source them separately.

How much better does a 3-row radiator cool compared to what I have now?

Three rows increase surface area and cooling efficiency, which keeps temperatures down during sustained heat — towing, desert driving, or summer traffic. Your stock setup may already be adequate; a 3-row upgrade is insurance against overheating in heavy use.
