Purpose and function in the transmission oil cooling system

The presented pipe/hose is a component from the Oil coolers and lines category, responsible for transporting transmission oil between the gearbox and the oil cooler. A correctly selected line guarantees:

• maintenance of stable oil flow across the entire gearbox load range,
• consistency with the factory mounting and routing system in the Ford S-Max,
• reduced risk of transmission oil overheating during intensive use.

By maintaining the original diameter and shape of the line, the oil cooling system operates under conditions close to factory specifications, which promotes the durability of the automatic transmission.

Benefits of using an original Ford line

The original Ford oil line ensures high installation compatibility with the factory cooling system. In practice, this means:

• no need for system modifications or custom mounting brackets,
• secure fit to the oil cooler and gearbox connectors,
• preservation of the manufacturer-designed line routing in the engine bay.

Such a solution is particularly beneficial when servicing the 2.2 TDCI transmission, where stable oil cooling has a direct impact on the smoothness of operation and the lifespan of the gearbox.

Condition, origin, and service application

This item comes from the used parts group, which allows for an economical repair of the oil cooling system while maintaining the original manufacturer specifications. Replacing the line is recommended in situations such as:

• detection of leaks or sweating at the joints,
• mechanical damage to the line (cracks, abrasions, deformations),
• modernization or regeneration of the transmission oil cooler.

Choosing an original line for the Ford S-Max with a 2.2 TDCI engine allows you to maintain the integrity of the entire system and reduce the risk of future oil temperature issues.

Technical support, cooling, and savings

When the drivetrain operates at high temperatures, it is crucial to ensure not only engine cooling but also efficient oil circulation in the gearbox.
