Installation and maintenance

For optimal performance, technicians should inspect the pump during routine belt service. When replacing this component, it is recommended to check the integrity of all cooling hoses and seals to prevent future leaks. Maintaining a clean cooling system helps extend the lifespan of the pump's internal bearings and seals.
