What This Radiator Helps Address

• Replacement needs after corrosion, impact damage, or seepage

Installation Notes and Tips

Verify radiator dimensions, hose connections, and cooler line routing before installation. Flush the cooling system, inspect hoses and clamps, and confirm the transmission cooler connections are clean and secure.
