Will this bolt directly into my current setup without adapter hoses?

Yes. This radiator uses factory connection points and mounting brackets, so your existing hoses fit without modification or adapters.

Do I need to drain and refill coolant for installation?

You'll need to drain the old coolant before removing the failed radiator. Disconnect the inlet and outlet hoses, unbolt from the frame, and reverse the process with the new unit. Basic hand tools and a drain pan are all you need.

What's the return process if there's an issue after I install it?

Contact ModSupply directly with photos of the damage or defect. Returns are handled case-by-case depending on whether the unit arrived damaged or failed in service.
