Additional information

1. The coolant pump ensures constant circulation of the coolant and prevents the engine from overheating.
2. A worn water pump can cause leakage, bearing play, or reduced cooling capacity.
3. Always check the version of the old water pump, the flange, the dimensions, and the number of mounting holes before ordering.

Advice for optimal protection of the cooling system

For a long lifespan of the radiator, water pump, and other components of the cooling system, we always recommend using the correct coolant.

For classic Mercedes models, this is usually a blue-green, silicate-based coolant that offers protection against corrosion, limescale, and internal degradation of the cooling system.

In addition, waterless coolant is an excellent alternative. It prevents internal corrosion, reduces the risk of boiling problems, and offers extra protection for classic engines.

1. Protects radiator and engine block against corrosion.
2. Prevents deposits and contamination in the cooling system.
3. Improves the reliability of the entire cooling system.
4. Extends the lifespan of important parts.

Both the blue-green silicate-based coolant and waterless coolant are available via our webshop.

Installation manual coolant pump water pump

1. Never carry out repair work while the engine is running.
2. Preparation
   Allow the cooling system to cool down completely and drain all coolant until the system is completely empty. Next, remove the water pump and carefully clean all sealing and mating surfaces. Remove all residues of old gaskets and sealants. We also recommend cleaning and flushing the entire cooling system. Check all components of the cooling system and replace them if necessary.

Warning: Never reuse drained coolant. Coolant is hazardous waste and must be disposed of in accordance with applicable regulations.

3. Installation of the new water pump
   Always install the new water pump with a new gasket. Tighten the mounting bolts to the torque specified by the vehicle manufacturer and check that the pump can rotate freely.

Warning: When using a silicone gasket or silicone sealant, the prescribed curing time must be fully observed before filling the cooling system with coolant. Never use too much.

4. Fan check
   Check the fan for damage and replace it if necessary. For vehicles with a fan clutch, its correct operation must also be checked.

Warning: A defective fan clutch can lead to premature failure of the new water pump.

5. Checking the drive belt
   Check the drive belt(s) for wear, deformation, and hardening. Replace worn belts, and we recommend always installing a new drive belt when replacing the water pump. Adjust the belt tension according to the vehicle manufacturer's specifications to prevent damage to the bearings of the driven components.

Warning: Always check the operation of the belt tensioner and replace it if necessary.

6. Hose inspection
   Check that all cooling hoses and hose clamps are in good condition and correctly installed.
7. Filling the cooling system
   Fill the cooling system with new coolant.

Warning: Use only coolant prescribed or approved by the vehicle manufacturer.

8. Vent
   Bleed the cooling system according to the vehicle manufacturer's instructions.

Warning: A slight leak may occur at the vent opening during bleeding.

9. Final inspection
   Test run the engine and check the entire cooling system for leaks. Also check that all cooling hoses and hose clamps are correctly installed. Then let the engine cool down and check the coolant level again. Pressure test the cooling system to check for leaks.

Important

1. Always consult the workshop manual for the relevant Mercedes model for specific installation instructions.
2. Installation must be carried out exclusively by qualified personnel.

Always check before purchase and installation whether the part is suitable and equivalent based on photos, description, and specifications; installed or used parts cannot be returned.
