Mercedes W176 C117 Engine Breather Bleed Line Pipe Hose A1330109500

Mercedes W176 C117 Engine Breather Bleed Line Pipe Hose is an original component from the Cooling system pipes and hoses group, designed for use in Mercedes power units. It ensures controlled gas discharge from the engine area, supporting stable cooling system operation and proper circulation of the working medium. Thanks to its factory geometry and fitment for the specific W176/C117 platform, it provides a precise service solution.

Function and application in the cooling system

The breather pipe in a Mercedes engine is responsible for the controlled discharge of air and gases from the circuit, which reduces the risk of air locks forming in the cooling system. A correctly selected hose:

• stabilizes coolant flow at critical points in the system,
• facilitates maintaining the proper operating temperature of the power unit,
• reduces the risk of local overheating resulting from air entrapment,
• supports even distribution of the coolant throughout the entire circuit. As a result, the cooling system operates predictably, and the engine maintains stable thermal parameters under typical operating conditions.

Original origin and fitment for Mercedes

The offered hose is a component intended for Mercedes vehicles, which means maintaining factory geometry, connection diameters, and mounting points. In practice, this translates into:

• trouble-free fitment with connectors and joints in the engine bay,
• correct routing of the hose relative to other components,
• preservation of the manufacturer's original cooling and venting concept. Additionally, using an original solution from the Cooling system pipes and hoses group reduces the risk of leaks typical of replacements with inaccurately reproduced geometry.

Characteristics of the used component

The hose comes from the secondary market, which allows for cost-effective restoration of system efficiency while maintaining the manufacturer's original specifications. The used component:

• is an attractive cost alternative to new parts,
• enables maintaining consistency with other cooling system elements,
• proves effective in service repairs where fitment and functionality are key. The product condition marked as used allows for a rational combination of durability and a favorable repair budget, while maintaining operating parameters consistent with Mercedes design assumptions.

Selection, identification, and system integration

For correct part identification, it is worth using the OEM part number designation and available interchangeable numbers, which facilitates matching the hose to the specific engine version in W176 and C117 bodies. Using the correct element:

• limits the risk of stress resulting from improper hose length or shape,
• ensures correct positioning relative to the fan, engine accessories, and electrical harnesses,
• facilitates service and potential future maintenance activities within the cooling system. For full compliance with the store's offer, you can also use the SKU identifier, which speeds up the ordering process and minimizes the risk of error.

Cooling system expansion and additional materials

If you are planning a comprehensive repair or upgrade of the engine area in your Mercedes and need other elements from the same group, such as additional pipes, return hoses, or flexible connecting sections, check the available parts in the Mercedes cooling system pipes and hoses category. When working on the cooling system and interior thermal comfort, it is also worth checking out practical tips regarding the selection of air conditioning elements – they are discussed in detail in the article No cooling in the car: original used air conditioning compressor as a proven alternative to expensive new ones, where you will find information on the principles of verifying used components and inspection before installation.
