Do I need to drain the entire cooling system to swap this in?

Yes. Disconnect both hoses, drain the system into a catch pan, then unbolt the radiator from the frame. Reverse the process with your new unit. Have a fresh coolant mix ready before refill.

Will this work with my existing hoses and thermostat housing?

Factory hoses and housing connect at the same points, so no adapter fittings are needed. Verify hose condition before reinstall — if they're original, consider replacing them at the same time.

What's the return window if this radiator doesn't fit?

Test-fit before you seal it into the engine bay. If it doesn't align with your mounting points or hose connections, reach out to us within 30 days for next steps.
