Will this bolt directly into my engine bay without any modification?

Yes. This radiator mounts at factory mounting points — no drilling, fabrication, or custom brackets needed. Drop-in replacement for the OEM unit.

Do I need to drain the cooling system before installation?

You'll need to drain the coolant from your existing radiator before removal. Have a drain pan ready and follow your vehicle's service manual for coolant capacity and fill procedures.

Does this come with hoses and clamps?

The assembly includes the radiator core only. Reuse your existing hoses and clamps if they're in good condition, or source replacements separately based on your vehicle's configuration.
