Frequently Asked Questions
Do I need to drain coolant before swapping this in?
Yes. Drain your system completely, disconnect hoses and mounting hardware at the radiator frame, and remove the old unit. Install the new radiator in reverse order and refill with coolant per your truck's service manual.
Are hose clamps and mounting bolts included?
The radiator assembly ships alone. You'll use your existing hoses and fasteners—test-fit before final tightening to confirm alignment at the frame.
What condition is this radiator in?
This is a remanufactured unit, meaning it's been disassembled, cleaned, and tested for leaks and core integrity. It performs like OEM new at a fraction of the cost.
