Detailed Product Information

Proper crankcase ventilation helps control pressure and vapor flow through the engine, which is important for consistent performance and long-term durability. Dorman 46097 is a replacement PCV hose engineered for Mercedes-Benz vehicles with lower full load crankcase ventilation routing, including applications such as the Mercedes-Benz E320, ML500, SL500, and CLK320. This hose uses NBR material to better withstand age-related hardening and splitting, making it a practical service part when the original hose shows signs of wear. This part number 46097 also cross-references 1120180482 for the same application.

What This Hose Helps Address

• Cracked or brittle PCV hose material
• Vacuum leaks from a deteriorated crankcase ventilation hose
• Rough idle caused by compromised ventilation routing
• Oil vapor leakage around a worn hose connection
• Loss of proper crankcase pressure control

Installation Notes and Tips

Verify the lower-position full load crankcase ventilation routing before installation. Compare the hose shape, length, and end diameters to the original part to confirm proper routing on the vehicle. This hose is listed for a wide range of Mercedes-Benz applications, including 1998-2006 Mercedes-Benz E320, 2000-2006 Mercedes-Benz S500, and 2001-2006 Mercedes-Benz CLK55 AMG, so matching the exact engine and ventilation layout is important. Dorman part number 46097 should be checked against the removed hose and vehicle configuration before service.

Quality Assurance

Dorman manufactures replacement parts using application-specific materials and dimensions to support reliable service fitment. The NBR construction and OE-style hose geometry are selected to replace the original ventilation hose on confirmed Mercedes-Benz applications.
