Will this radiator work as a direct bolt-in replacement?

Yes. This radiator mounts at the factory attachment points — no drilling, fabrication, or adapter brackets required. Remove the old unit and bolt this one in using the original hardware locations.

Do I need to flush the cooling system before installation?

Flush the system before you install the new radiator. Old coolant may contain sediment or corrosion particles that can clog the new core and reduce heat transfer efficiency. Use distilled water and a coolant flush product according to your truck's service manual.

Does this come with hoses or clamps?

The radiator assembly includes mounting brackets, but radiator hoses and clamps are separate items. Reuse your existing hoses if they're in good condition, or source new hoses to match your truck's configuration.
