• Impeller: steel construction with 10 vanes, reverse rotation
• Mounting: 10 mounting holes and 4 hub holes to match factory patterns
• Drive type: serpentine belt compatible

How does this pump improve engine cooling and reliability?

A properly functioning water pump maintains coolant flow and system pressure so the engine’s cooling passages receive continuous circulation. The A-Premium pump is manufactured and tested to tight tolerances to reduce leaks, cavitation and premature wear compared with worn or damaged originals.

• Tested to strict quality standards to limit leakage and shaft play
• Steel impeller resists deformation and maintains flow under load
• Aluminum housing resists corrosion and aids heat transfer
• Direct-fit mounting reduces installation time and alignment issues

Which reference numbers and part cross-references should I check?
