The Gates emission control hose for 1998–2003 Mercedes‑Benz E320 V6 3.2L links the changeover valve to the check valve within the emissions control plumbing. This hose replaces the factory changeover-to-check valve line, preserving the intended routing that manages vacuum and flow between those components as part of the vehicle's emissions and crankcase ventilation system.
