This manual provides essential information for the proper installation, operation, and maintenance of your Mercedes-Benz 001 835 13 64 Engine Auxiliary Water Pump. Adhering to these instructions will help ensure the longevity and optimal performance of the component. This genuine Mercedes-Benz part is designed for direct replacement in compatible vehicles.
Bidhaa Imeishaview
The Mercedes-Benz 001 835 13 64 is an Engine Auxiliary Water Pump, also known as a re-circulator pump. Its primary function is to circulate coolant within specific systems of the vehicle, often for the heating system or to provide additional cooling to certain engine components, independent of the main engine-driven water pump. This ensures efficient temperature regulation and passenger comfort.

Figure 1: Auxiliary Water Pump System Diagram
This diagram illustrates the auxiliary water pump (1) and its connection within the vehicle's coolant circulation system. Key components shown include the pump (1), its mounting clip (2), various coolant hoses (3, 4, 7, 8), a control valve (5), and an engine component (6) to which the system connects. Hoses (7) and (8) typically lead to the vehicle's heater core or an auxiliary heat exchanger.
Taarifa za Usalama
- Always allow the engine to cool completely before attempting any work on the cooling system. Hot coolant and engine components can cause severe burns.
- Wear appropriate personal protective equipment (PPE), including safety glasses and gloves, when working with automotive fluids and components.
- Coolant is toxic. Avoid ingestion and contact with skin. Dispose of used coolant responsibly according to local regulations.
- Disconnect the vehicle's battery before beginning installation to prevent electrical hazards.
- If you are unsure about any step, consult a qualified Mercedes-Benz service technician.
Kuweka na Kuweka
This auxiliary water pump is designed for direct replacement. Professional installation is highly recommended due to the complexity of automotive cooling systems and the need for specialized tools and knowledge.
Hatua za Ufungaji (Mwongozo wa Jumla):
- Maandalizi: Ensure the engine is cool. Park the vehicle on a level surface and engage the parking brake. Disconnect the negative terminal of the vehicle's battery.
- Drain Coolant: Place a suitable drain pan under the radiator and open the drain cock to drain the engine coolant. Some coolant may also need to be drained from the engine block or specific hoses.
- Locate and Remove Old Pump: Identify the existing auxiliary water pump. Refer to Figure 1 for typical component layout. Carefully disconnect electrical connectors and coolant hoses (3, 4) from the old pump. Be prepared for residual coolant to spill. Remove any mounting hardware (e.g., clip 2) and detach the old pump.
- Sakinisha Pampu Mpya: Position the new Mercedes-Benz 001 835 13 64 auxiliary water pump in the correct location. Secure it with the appropriate mounting hardware (e.g., clip 2).
- Connect Hoses and Electrical: Reconnect the coolant hoses (3, 4) to the new pump, ensuring they are securely clamped to prevent leaks. Reconnect the electrical connector.
- Jaza tena Kipozezi: Close the radiator drain cock. Refill the cooling system with the correct type and amount of Mercedes-Benz approved coolant. Follow the vehicle manufacturer's specific bleeding procedures to remove air from the system.
- Mfumo wa Mtihani: Reconnect the battery. Start the engine and allow it to reach operating temperature. Monitor the coolant level and check for any leaks around the new pump and hose connections. Ensure the vehicle's heating system functions correctly.
Kanuni za Uendeshaji
The auxiliary water pump operates electrically, independent of the engine's rotational speed. It is typically controlled by the vehicle's engine control unit (ECU) or climate control module. Its operation ensures consistent coolant flow to systems like the heater core, providing cabin heat even at low engine RPMs or when the engine is off (e.g., for residual heat function). It may also be used to cool specific turbocharger components or other auxiliary systems.
Matengenezo
The Mercedes-Benz 001 835 13 64 auxiliary water pump is a sealed unit and does not require routine maintenance beyond ensuring the overall health of the cooling system.
- Kiwango cha Kupoa: Regularly check the coolant level in the expansion tank and top up with Mercedes-Benz approved coolant as needed.
- Ukaguzi wa Hose: Periodically inspect all coolant hoses connected to the pump for signs of wear, cracks, or leaks. Replace any damaged hoses immediately.
- System Integrity: Ensure the entire cooling system is free of leaks and that the coolant is clean and free of contaminants.
Kutatua matatizo
If you experience issues related to the auxiliary water pump, consider the following common symptoms and potential causes:
| Dalili | Sababu inayowezekana |
|---|---|
| No heat or insufficient heat in the cabin | Faulty auxiliary water pump, low coolant level, air in cooling system, faulty control valve (5 in Figure 1), electrical issue. |
| Engine overheating (less common for auxiliary pump) | While primarily for auxiliary systems, a severe malfunction could contribute to overall cooling issues. More likely main water pump or thermostat. |
| Coolant leak near the pump | Hose huru clamps, damaged hoses, faulty pump seal. |
| Unusual noise from pump area | Internal pump failure, debris in the system. |
For accurate diagnosis and repair, it is recommended to consult a qualified Mercedes-Benz service technician.
