Installation Notes

Verify the 5/8 in. inside diameter at both ends before installation and confirm the hose routing matches the throttle body to intake manifold path on the vehicle. Inspect adjoining fittings, clamps, and coolant passages for wear or contamination before replacing the hose. On Chevrolet C1500 and GMC K2500 applications, correct routing and secure connections are important for leak-free heater hose service.
