Installation Notes and Tips

Before installation, inspect the hose routing path to confirm compatibility with your vehicle’s engine bay layout. Ensure all clamps and fittings are clean and free of corrosion. The protective sleeve on this hose helps reduce abrasion, but care should be taken to avoid sharp edges during installation. Verify that the hose is seated fully on the radiator and engine fittings to prevent leaks. No heat shield is included, so additional heat protection may be necessary in high-temperature areas.
