The Gates emission control hose for 1996–2004 Chevrolet S‑Series Pickup with the 4.3L V6 routes crankcase ventilation by linking the valve cover to the intake tube. It replaces the original emission hose to restore proper PCV/vent routing and maintain the engine’s emissions plumbing. Use it when the factory hose is cracked or leaking to keep the system sealed and functioning.
