Will this bolt directly into my engine bay or do I need to modify anything?

This mounts at factory rocker points — no drilling or bracket fabrication needed. Your existing hose connections and mounting hardware will align with the original setup.

What condition is the radiator in when it arrives?

It ships as a complete assembly ready for installation. Flush your cooling system and verify hose diameter before connecting to ensure a tight seal.

Do I need any coolant or gaskets that aren't included?

This is the radiator core and tanks only. Plan to purchase fresh coolant, new hoses if yours show wear, and thermostat gasket material based on your vehicle's service manual.
