2011-2015 Hyundai Sonata / Kia Optima OEM Radiator 2.4L Hybrid

Do I need a new radiator hose or thermostat when I install this?

Not necessarily. If your existing hoses are in good condition and the thermostat is functioning, you can reuse them. Inspect hose condition during install—if they're cracked or brittle, replace them at the same time to avoid a second tear-down.

Does this radiator come with mounting hardware and clips?

The radiator assembly ships with factory mounting points ready to bolt in. Verify your existing fasteners and brackets are in serviceable condition before installation.

Can I flush and reuse my old coolant, or should I do a full system drain and refill?

You'll need to drain the system to remove the old radiator anyway. A full coolant replacement is the best practice when swapping radiators—it removes sediment and keeps your hybrid cooling system operating at peak efficiency.
