Frequently Asked Questions

Do I need a new thermostat or hoses when I swap this in?

Not necessarily. If your existing hoses and thermostat are in good condition, reuse them. Inspect rubber hoses for cracks or soft spots before installation — if they look worn, replace them now while you have the radiator out.

Will this radiator work with my current cooling system without flushing?

Flush your cooling system before installing the new radiator. Old coolant can clog a fresh unit and reduce performance. Use distilled water and a flush kit, drain completely, then fill with fresh coolant rated for your vehicle.

What if the radiator arrives damaged?

Inspect it immediately upon delivery. If you spot cracks, leaks, or bent fins, contact our support team with photos — we'll handle a replacement or return right away.
