Installation Notes and Tips

Confirm the hose routing and end diameters before installation, especially on upper radiator hose applications. Inspect adjoining clamps, radiator necks, and engine fittings for corrosion or damage before installing the new hose. After installation, refill the cooling system with the correct coolant and check for leaks once the engine reaches operating temperature.
