Installation and maintenance

For optimal service, technicians should inspect the pump during routine belt replacements. When installing this component, ensure all sealing surfaces are clean to prevent leaks. Maintaining the integrity of the cooling circuit is vital for preventing long-term engine wear caused by thermal fluctuations.

Troubleshooting guidance
