Installation Notes and Tips

Before installation, verify that the hose dimensions match the vehicle’s radiator and engine connections. The 2 1/4 inch inside diameter ends should fit securely without forcing. Ensure clamps are properly tightened to prevent leaks but avoid overtightening, which can damage the hose. Since this hose does not include a heat shield or protective sleeve, consider routing it away from high-heat components to extend service life.
