Audi RS6 C7 RS7 4G Engine Coolant Pipe Rear Left N/S 4.0 TFSI 079121071CM

Audi RS6 C7 RS7 4G Engine Coolant Pipe Rear Left N/S 4.0 TFSI is an original cooling system component designed for operation in the rear left section of the engine bay. Thanks to its precise fitment to the 4.0 TFSI unit specifications, it ensures stable coolant flow and supports safe thermal conditions for the engine. This is a solution for users who expect factory compatibility, secure installation, and predictable performance.

Purpose and function in the cooling system

The presented pipe belongs to the Cooling system pipes and hoses group and is responsible for transporting coolant in the rear left zone of the power unit. The rear-left vehicle placement allows for precise routing of the cooling medium between system components, minimizing the risk of kinks, localized overheating, and leaks. A properly selected water hose in this area is crucial for:

• maintaining a stable operating temperature of the 4.0 TFSI engine,
• proper fluid circulation in the rear part of the engine block,
• reducing thermal loads on components adjacent to the pipe.

Original origin and fitment for Audi

As an Audi brand component, the pipe has been designed for full integration with the factory cooling system of the RS6 C7 and RS7 4G models. This means maintaining the correct geometry, connection diameters, and routing relative to other components, which facilitates installation and reduces the need for additional modifications. By using an original solution, the user gains:

• certainty of compliance with the factory cooling system architecture,
• stable mounting in factory attachment points,
• consistency with other pipes and hoses in the vehicle.

Installation and operational characteristics

The placement of the pipe in the rear left part of the vehicle requires a component with a properly designed path, resistant to temperature and working conditions in the vicinity of engine elements. This water hose has been prepared for operation in the demanding environment of the 4.0 TFSI unit, where maintaining tightness and resistance to temperature changes over a long service life is essential. This solution will work particularly well in situations where:

• the existing pipe shows signs of wear, cracks, or leaks,
• a cooling system repair is being carried out in the rear part of the engine,
• it is necessary to restore the factory routing of pipes after previous modifications.

Condition of the item and benefits of choosing a used part

The offered pipe comes from the used parts group, which allows combining original origin with a more favorable purchase cost. For many RS6 and RS7 users, this is a reasonable compromise between quality and budget, especially during comprehensive service work within the cooling system. Choosing a used water pipe means, among other things:

• the ability to maintain the original specification at lower financial outlays,
• better fitment than in the case of many low-budget replacements,
• reducing the risk of installation problems resulting from imprecise geometry.

Technical support and additional materials

To better plan the cooling system service in your Audi, it is worth checking out the guide on system operation at high temperatures. Practical tips on how to optimally take care of engine cooling and how to reasonably use used parts can be found in the article Summer heat vs. cooling system: used radiators and fans as a guarantee of savings. If you are planning a comprehensive repair or upgrade of the cooling system area in your Audi and need other elements from the same group, such as additional pipes, water hoses, or flexible connecting sections, check the available parts in the Audi cooling system pipes and hoses category.
