Do I need new hoses or fittings to install this?

Factory hoses and clamps will work with this radiator if they're in good condition. If hoses show cracks or age, swap them while you have the system open — common maintenance move.

Can I flush the cooling system without removing the radiator first?

You can flush through the block without pulling the radiator, but a full system flush is cleaner if you're already replacing the core. Either way, drain the old coolant completely before install.

What condition is this radiator in — new, rebuilt, or used?

Confirm condition status before checkout. OEM radiators arrive tested and ready to install, but clarity on whether it's new or rebuilt affects your installation timeline and expectations.
