Audi A4 S4 8K A5 S5 8F 8T Additional Coolant Pump Bracket Mount 8K0145879D

Audi A4 S4 8K A5 S5 8F 8T Additional Coolant Pump Bracket Mount is an original component from the Water pumps group, designed for the stable mounting of an additional coolant pump in selected Audi models. It ensures precise positioning of the pump relative to the cooling system, which promotes uniform fluid flow and the proper operation of the entire system.

Purpose and function in the cooling system

The bracket is responsible for the rigid, repeatable mounting of the additional coolant pump in A4/S4 8K and A5/S5 8F/8T series vehicles. Thanks to its tailored geometry and factory mounting points, this component:

• maintains the pump in the correct position relative to the cooling system hoses and connectors,
• reduces vibrations transmitted to the pump and adjacent components,
• minimizes the risk of stress on connectors and joints,
• supports stable system operation under high thermal load conditions.

Such a solution is particularly important in higher-power units, where the additional coolant pump operates across a wider range of temperatures and loads.

Construction and OEM fitment

As a component prepared by the vehicle manufacturer, the bracket is characterized by factory-perfect fitment to the body and engine accessories. This means compatibility with original mounting points and appropriate structural rigidity, selected for the loads generated by the operating pump.

In practice, this translates into:

• easier installation without the need for modifications,
• proper routing of coolant hoses within the engine bay,
• preservation of the entire cooling system geometry as designed by Audi.

Component condition and service application

The offered bracket comes from the secondary market, making it an attractive solution for repairs and service cost optimization. This type of structural element, while maintaining correct geometry and mounting points, can be successfully used as a replacement for a damaged or corroded mount.

Replacement of the bracket is recommended, among other situations, when:

• mechanical damage to the mount has occurred (cracks, broken lugs),
• deformations affecting the pump's position are visible,
• after a collision or bodywork repairs, it is necessary to restore the factory routing of the cooling system.

Benefits of using an original bracket

Using an original additional coolant pump bracket instead of a universal part or makeshift mount allows for maintaining the structural integrity of the cooling system. This is significant for both the durability of the pump and the stability of engine operation across a wide temperature range.

Key advantages include:

• preservation of the rigidity and vibration damping designed by the manufacturer,
• lower risk of leaks resulting from stress on hoses,
• easier diagnostics and service thanks to the factory layout of components.

Selection by part numbers and technical support

The bracket is assigned to specific Audi model configurations, which is why it is worth using manufacturer markings and vehicle data when selecting. Verifying compatibility via catalog numbers and VIN helps avoid installation problems and ensures full compatibility with a given body and engine version.
