Installation Notes and Tips

Verify inlet and outlet hose sizes, cooler line routing, and overall core dimensions before installation. Inspect mounting points, fan shrouds, hoses, and clamps during radiator replacement to confirm the cooling system is clean and free of debris. Flush the system as needed and refill with the correct coolant specification for the vehicle. After installation, check for leaks and confirm proper operating temperature during a road test.
