Will this bolt directly to my existing radiator and shroud?

Yes — this fan uses factory mounting points. Your existing shroud, hoses, and core don't need modification. Bolt it in and connect the original electrical plug.

Do I need to drain my coolant to swap this out?

Not necessarily. You may be able to slide the fan assembly out without disturbing the radiator itself, depending on your engine bay layout. If you're uncertain, draining and removing the radiator gives you the cleanest access and lets you inspect the core while you're in there.

What if my fan clutch is still good — can I reuse it?

That depends on whether your original clutch bolts to the fan blade or the water pump pulley. Check your truck's service manual or verify your clutch design before ordering. If your clutch bolts directly to the fan, you'll transfer it to this new blade.
