Do I need new hoses and clamps when I install this?

Inspect your existing hoses for cracks or hardening before reinstalling them. If they're original and cracked, replace them—hose failure and coolant loss will ruin a new radiator fast. Clamps can be reused if they still clamp tight.

Will I need to flush the cooling system after installation?

Yes. Run a complete flush before dropping in the new radiator. Old coolant sediment clogs a fresh core immediately. Use the coolant type specified in your owner's manual.

Does this come with a thermostat or water pump?

Radiator assembly only. If your thermostat or water pump is original, consider replacing those at the same time—you've already got the system open and cooling work compounds fast.
