Frequently Asked Questions
Do I need to drain the entire cooling system before installing this?
Yes. Drain the coolant fully before removing the old radiator. Disconnect the inlet and outlet hoses, unbolt from the radiator support, then bolt the new unit in place. Refill with fresh coolant and bleed air from the system per your service manual.
Will this bolt straight into my truck without modifications?
Yes. This radiator uses factory mounting points on the radiator support—no drilling, cutting, or welding required. The diagonal inlet matches the OEM coolant lines on your platform.
What condition is the radiator in—is it new or rebuilt?
Test-fit before committing final installation. If any leaks appear during initial operation, contact support with photos for replacement options.
