Detailed Description
URO 1040943682 is an engine crankcase breather hose for Mercedes-Benz crankcase ventilation systems. It is built from EPDM and formed as a molded hose to match the original routing between the upper and lower intake manifold. Replacing a failed breather hose helps restore proper crankcase ventilation and hydrocarbon emission control. This part number, 1040943682, is used across multiple Mercedes-Benz platforms and is a practical OE-style replacement for aging factory hoses.
What It Helps Address
- Cracked or split crankcase breather hose
- Oil vapor leaks at the ventilation hose connection
- Improper crankcase ventilation flow
- Emission control issues related to a failed breather hose
- Heat-related hose hardening and deterioration
