Will I need new hoses or can I reuse my old ones?

Inspect your existing hoses for cracks or soft spots. If they're original to the vehicle, it's smart to replace them while you have the radiator out—hoses degrade over time and a failure shortly after radiator swap isn't worth the hassle.

Do I need to flush the cooling system before installing this?

Yes. Run distilled water through the system to clear out old coolant and sediment, then refill with fresh 50/50 coolant mix. Old fluid can clog a new radiator fast.

Is there a return window if it doesn't fit?

Factory mounting points match OEM spec, so fitment is solid. Verify your vehicle year and engine size before checkout—those details determine compatibility.
