The Gates emission control hose for 1998–2005 Mercedes‑Benz E320 with the 3.2L V6 links the valve cover to a left‑side connector, restoring part of the vehicle’s crankcase ventilation routing. Replace this hose when worn or cracked to reestablish the sealed connection on the left side and maintain correct emissions plumbing and vapor flow in the engine compartment.
