Purpose and function in the oil cooling system

The presented hose is a component of the gearbox oil cooling system, mounted on the right side of the vehicle. It is responsible for precisely delivering transmission oil to the oil cooler and then returning it to the gearbox, which helps maintain a stable operating temperature for the transmission during city driving, highway travel, and under high-load conditions.

Thanks to its dedicated design for Diesel units, the hose is adapted to the thermal and pressure characteristics of the system in diesel engines, which promotes long-term and predictable operation of the entire powertrain.

Construction and fitment for Mercedes S W220

The hose has been designed specifically for the Mercedes S-Class W220 generation, which means proper routing in the engine bay, correct mounting points, and compatible connection ends. Such fitment reduces the risk of stress, leaks, and collisions with other equipment components.

The original origin from the Mercedes brand helps maintain the factory geometry of the oil cooling system and facilitates installation for mechanics familiar with the standard solutions used in this model. This is a beneficial solution for gearbox repairs, oil cooler replacements, or fixing leaks within the lines.

Performance parameters and application

The hose is intended for installation on the right side of the vehicle, which is important for identifying the correct part during repair. The construction is adapted for operation in systems powered by diesel fuel, where thermal and pressure loads are specific to diesel engines.

The component comes from the Oil coolers and lines category, making it a perfect fit for repairs related to transmission oil temperature control, improving gearbox stability, and reducing the risk of overheating in used Mercedes S W220 vehicles.

Condition, origin, and identification

The offered hose is a used component, which allows for economical repair while maintaining the manufacturer's original specifications. This is a good solution for users who want to restore the efficiency of the oil cooling system without having to invest in a new component, while maintaining compatibility with the factory design.

Additionally, the part has an assigned OEM number and available interchangeable numbers, which facilitates verification of compatibility with a specific engine version and gearbox. Identification in our store is also supported by the SKU, allowing for quick retrieval of the correct product in case of a repeat purchase or technical consultation.
