Bracket Purpose and Function

The presented bracket is dedicated to Mercedes E-Class W212 models with the OM651 engine, where it is responsible for the stable support of the vacuum tank cooperating with the EGR cooler. Proper mounting of this component is important for:

• maintaining the correct position of the tank relative to the vacuum lines,
• reducing vibrations transmitted to the EGR system and engine accessories,
• minimizing the risk of damage to vacuum lines, nipples, and connectors,
• preserving the factory routing of the installation in the engine bay.

By using the original bracket, it is possible to recreate the factory mounting configuration, which facilitates servicing and diagnostics of the intake and exhaust gas recirculation system.

Benefits of Using an Original Mercedes Part

The OEM version of the EGR cooler vacuum tank bracket ensures a perfect fit with the factory mounting points on the body and engine accessories. In practice, this means:

• no need for modifications or custom-made brackets,
• a secure fit with existing bolts and supports,
• easier installation and removal during subsequent service work,
• maintaining a clear layout of lines in the engine bay.

Using original mounting solutions is particularly important in the EGR and vacuum system area, where mounting stability affects long-term sealing and the correct operation of vacuum-controlled components.

Product Characteristics and Condition

The offered bracket belongs to the group of engine accessory mounting components responsible for the proper arrangement of sub-assemblies in the engine bay. As a used part, it comes from disassembly, which allows for maintaining the original mounting specification typical of factory Mercedes solutions. This type of component is particularly useful for:

• replacing a damaged or missing bracket after a collision or body repairs,
• restoring the factory configuration after previous modifications,
• comprehensive servicing of the EGR system and OM651 engine accessories.

Using the original bracket helps avoid makeshift solutions that could lead to excessive stress, chafing of lines, or improper positioning of the vacuum tank.

Integration with the EGR System and OM651 Accessories

In the OM651 engine, the EGR system works with an extensive vacuum system, and the vacuum tank acts as a buffer ensuring proper control of valves and actuators. A properly selected bracket:

• maintains the tank in the position designed by the manufacturer,
• prevents excessive stress on nipples and connectors,
• facilitates service access to lines and EGR cooler components,
• supports the maintenance of a clear, organized engine bay.

For workshops specializing in OM651 unit servicing and users who care about the technical correctness of repairs, using the correct vacuum tank bracket is an important element of comprehensive exhaust gas recirculation system maintenance.
