Do I need to replace hoses and clamps when I install this?

Your existing hoses and clamps will work if they're still in good condition. If you're seeing weeping or cracks, now's the time to swap them out. Inspect both upper and lower hoses before you button everything back up.

What about coolant — do I need to flush the system first?

Flush the old coolant out before dropping in the new radiator. Fresh coolant helps the new core stay clean and extends its lifespan. Use whatever coolant spec your owner's manual calls for.

Does this come with a thermostat housing or just the radiator?

This is the radiator assembly only. Thermostat housing and water pump stay on your engine — no removal needed. Make sure all connections are clean before you bolt this in.
