Do I need to flush my cooling system before installing this radiator?

Yes. Old coolant can contain sediment and corrosion particles that will restrict flow in a new radiator. Flush the system completely, rinse with distilled water, and refill with fresh coolant rated for your vehicle.

Are hoses and clamps included, or do I need to buy them separately?

Hoses and clamps are not included. You'll need to reuse your existing hoses if they're in good condition, or source new ones to match your inlet and outlet ports. Check hose condition before installation — old rubber can crack under pressure.

What's the return process if the radiator doesn't fit or is damaged on arrival?

Contact ModSupply's customer service with photos of any damage or fitment issues. Return window and restocking policies are handled on a case-by-case basis — reach out before opening the packaging.
