Purpose and Function of the Oil Line

The automatic transmission oil line is responsible for transporting transmission oil between the transmission and the oil cooler located at the front of the vehicle. A correctly selected component:

• ensures stable oil flow in the automatic transmission system,
• supports maintaining the correct transmission operating temperature,
• reduces the risk of overheating and component wear,
• minimizes the risk of leaks at connections due to proper fit.

For Mercedes models in the R171, W204, and W212 series, using the appropriate oil line is crucial for maintaining the correct operation of the automatic transmission and its long-term service life.

Construction and Fit for the Oil Cooling System

The offered line is designed for installation at the front of the vehicle, where it works with the transmission oil cooler. The line's construction is prepared for operation in high-temperature and high-pressure systems, typical for automatic transmissions.

Thanks to its factory fit for specific Mercedes models:

• correct connector diameters and line routing are maintained,
• installation occurs at existing mounting points,
• there is no need to modify the oil cooling system or the transmission.

Benefits of Using an Original Oil Line

Using an oil line dedicated to automatic transmissions in Mercedes R171, W204, and W212 models brings tangible operational benefits:

• Stable Automatic Transmission Operation – proper transmission oil flow supports smooth gear changes.
• Improved Heat Dissipation – an efficient line working with the oil cooler reduces transmission overheating.
• Reduced Leaks – a proper fit of the connectors minimizes the risk of leaks at critical points in the system.
• Compatibility with Factory System – no need for adapters or installation modifications.

Condition, Service Application, and Installation

This part is a used component and is intended for service applications in Mercedes vehicles equipped with an automatic transmission. It is a practical solution for:

• repairs after mechanical damage to the front of the vehicle,
• eliminating oil leaks from the transmission cooling system,
• comprehensive automatic transmission service combined with oil change.

Installation by a workshop experienced in servicing Mercedes automatic transmissions is recommended to ensure system integrity and correct line routing in the engine bay.
