• Leak-tested units to ensure immediate reliability out of the box
• Designed to tolerate imbalance and engine vibration commonly seen in V8 applications

What should I verify before installing this pump?

Confirm the pump’s OEM cross-reference or compare the old pump’s mounting and pulley pattern to ensure a correct match. Consider replacing associated coolant hoses, thermostat, and belt/drive components if they show wear to avoid repeated labor.

• Match OEM numbers (e.g., 12656810 and listed cross-references)
• Verify engine displacement and model-year compatibility
• Inspect and, if needed, replace belts, hoses, and coolant when installing the pump
