DOLZ offers a selection of water pumps valid for Volkswagen Group vehicle models, that is, Audi, Seat, Škoda & Volkswagen brands with the possibility of being purchased with or without back housing.
These water pumps have an outer shell that encases the water pump, the back housing, which incorporate the thermostat and the temperature sensor, precisely directing the coolant flow.
During fitting, some things must be considered so that the assembly is carried out professionally and thus avoid future breakdowns. Therefore, in today’s article we learn about best practices and see in detail an overview of the DOLZ water pump with back housing range for Audi, Seat, Škoda and Volkswagen applications.
Best installation practices for water pump housing Audi, Seat, Škoda & Volkswagen:
The lifespan of this component arose depends on the maintenance that we will carry out on the complete cooling system, including the water pump and its associated elements, also the quality and choice of the coolant, and it stood out from the fact that the pump was assembled in effective way.
In many cases, the failure of these water pumps is due to errors during the installation process and not due to the quality of the component itself. For this reason, the key points during assembly that we consider essential are:
- The seal must never be oiled, otherwise the function of separating the “wet” and “dry” zones of the water pump will not work correctly and it will contaminate it, considerably reducing its lifespan.
- Avoid the use of additional sealant. From DOLZ we always inform that the use of sealant is only necessary in those references supplied without a gasket.
- Observe the specifications for tightening, sequence of tightening and recommended tightening torque values. It is essential to follow the correct order of screwing in the bolts and the tightening torque so that the water pump does not suffer a breakage.
- Last but not least, these pumps are supplied with a yellow rubber protective cup over the pulley ventilation wings. It is essential that this protective cup is only removed after assembly has been completed.
