Attention:
When working in the engine compartment, to avoid injury, it is necessary to take precautions, since the electric fan of the engine cooling system may turn on unexpectedly.
To avoid getting severe burns when the engine is hot, you must follow these rules:
- do not open the expansion tank cap,
- do not drain the fluid from the engine cooling system,
- do not open the lids to remove air.
Note: When performing work, be prepared for liquid leakage, so prepare a tray to collect the liquid and cover the surrounding components.
Removal and installation the water pump of the D4F engine
Note:
- When replacing the water pump, it is necessary to apply threads to the mounting holes of the new water pump, to which the timing cover will be attached. The pump is supplied by the manufacturer with standard holes.
- To cut the threads in these holes, it is necessary to use the self-tapping bolts of the timing cover. These bolts must be purchased together with the water pump. Only new self-tapping bolts must be used to cut the threads.
Loosen the mounting bolts and remove the water pump from the engine.
Installation is carried out in reverse order.
Tightening torque of self-tapping bolts: 12 N·m.

4. Remove the timing belt.
5. Loosen the bolts (1) and remove the water pump with the gasket.
Installing a water pump
Attention:
- To ensure the required tightness, the sealing surfaces must be clean, dry and free of grease (avoid any fingerprints).
- Do not scratch the connecting aluminum surfaces, any damage to the contact surfaces may result in leaks.
1. Use a cleaning agent to clean and degrease the contact surfaces of the cylinder block and the water pump if it is reused.
2. Install the water pump with a new gasket.
3. Apply one or two drops of FRENETANCHE locking compound to the bolts (1) and (4) of the water pump.
4. Tighten the water pump bolts in the sequence shown to the specified tightening torques:
- bolt M8 (1): 22 Nm;
- bolts MB (2-8): 11 Nm.
5. Further installation is carried out in the reverse order of removal.
6. Fill and bleed the engine cooling system.
