Make a preliminary diagnosis by observing whether there is water leakage around the pump and listening to whether there is abnormal noise in the pump.

5. Assemble the water pump: After replacing the parts, reassemble the water pump. Make sure that each component is installed correctly, and tighten the bolts according to the specified torque.

6. Install the water pump: Install the repaired water pump back to the engine and connect the pipeline of the cooling system. Pay attention to ensure that the seal is installed correctly during installation to prevent water leakage.

7. Add coolant: Finally, add an appropriate amount of coolant and exhaust the cooling system. Start the engine and check whether the water pump works normally and whether there is water leakage.

Generally speaking, repairing automobile water pumps requires careful inspection, replacement of damaged parts, correct assembly and installation. If there is no relevant experience and skills, it is recommended to seek professional automobile maintenance technicians for repair to ensure the normal operation and safety of the water pump.
