Installation Notes and Tips

When installing the Dayco Curved Radiator Hose 72139, ensure the hose is routed without twisting to maintain proper coolant flow. Verify that the 2 1/4 inch inside diameter matches the vehicle’s radiator and engine fittings. Since this hose does not include a heat shield or protective sleeve, inspect the surrounding engine components to confirm no excessive heat exposure that could damage the hose. Use appropriate clamps to secure the hose ends firmly and check for leaks after installation.
