Crank Case Breather Pipe Hose - Gates EMH522

It allows crankcase vapors to escape, preventing pressure buildup and directing them back into the intake system or to a separate catch can, which helps reduce emissions and prevent oil leaks.

Symptoms can include rough idling, increased oil consumption, oil leaks, whistling noises from the engine bay, or a physically degraded hose (cracked, brittle, or collapsed).

No, this hose is specifically designed for certain Mercedes-Benz models. Always verify fitment using the OEM part number cross-reference or a vehicle-specific fitment tool.

NBR stands for Nitrile Butadiene Rubber, a synthetic rubber known for its excellent resistance to oil, fuel, and heat, making it ideal for automotive applications.

The hose has a length of 190 mm and features two inner diameters: 18.5 mm and 27 mm.

If you have basic mechanical knowledge and the necessary tools, installation may be feasible. However, if you are uncertain, it is best to have it installed by a qualified mechanic to ensure proper fitment and function.

Warranty information typically varies. Please refer to the retailer's specific warranty policy or contact Gates customer support for details.

Ensure you have the correct hose for your vehicle model. Slightly warming the ends of the hose with a hairdryer (not direct heat) can make it more pliable for connection. Verify no obstructions are present at the connection points.

Double-check that all connections are secure and airtight. Inspect other components of the ventilation system for faults, such as clogged filters or other damaged hoses. Ensure the correct part was installed for your specific vehicle.

Re-seat the hose and ensure the clamps (if applicable) are tightened correctly. Check for any damage to the surfaces where the hose connects; they should be clean and smooth.
