Frequently Asked Questions
Will this radiator work with my current hoses and connections?
This is a direct OEM replacement, so factory hose connections and mounting points align with your truck's existing setup. If your original hoses show age or cracks, replacing them at the same time is smart preventive maintenance.
Do I need a new thermostat when I install this radiator?
Not required. Your existing thermostat will work fine with this OEM radiator. If you're experiencing temperature swings or leaks from the thermostat housing, address those separately before or after the radiator swap.
What if the radiator leaks after I install it?
Each unit gets an in-house quality check before shipment. If it arrives damaged or fails shortly after installation, contact our support team with photos—we'll work with you on a replacement or return.
