Installation Notes and Tips
Verify the end inside diameters before installation: 2 1/4 in. on one end and 2 1/2 in. on the other. Match the hose shape to the original routing and inspect clamps, necks, and adjoining pipes for wear before reassembly. This hose does not include a heat shield or protective sleeve, so confirm surrounding clearance and heat exposure during installation. For vehicle-specific searches, confirm the application against the original hose on the Navistar truck or other make/model listed in your service information.
