Installation Notes and Tips

• Verify the vehicle’s year, model, and pump position before ordering.
• Confirm clockwise rotation and port layout match the original unit.
• Inspect related cooling system components, including hoses and mating parts, during replacement.
• Because gasket or seal is not included, reuse or replacement of sealing components should be planned separately as needed.
• Follow factory service procedures for coolant system bleeding and final leak checks after installation.
