Note. Repairing the water pump usually does not lead to the desired result, so it is recommended to replace the pump assembly.
1. The water pump must be replaced if:
- during operation, a coolant leak from the pump was noticed;
- there is a noticeable axial play of the pump shaft (more than 0.13 mm);
- cracks, chips, spalling were found on the impeller 1, pulley 3 or casing 2 of the pump.
The bearing with the roller is fixed in the pump housing with a locking screw 4. For tightness, a gasket 5 is installed between the pump housing and the cylinder block.
2. Install the water pump in the reverse order of removal, replacing the gasket. After that, adjust the tension of the camshaft drive belt and fill in the coolant (see subsection 11.5.7.).
