Compatibility and Fitment
Use 252-595 only where the vehicle manufacturer or parts catalogue specifies this exact ACDelco number. Before installation, confirm hub height, pulley/clutch pattern, hose connections and gasket style against the engine variant. Consequently, match the pump to the VIN or engine code to ensure correct fit.
Compliance and Safety
Follow the vehicle service manual for torque values, sealant use and belt tension. Always drain and dispose of coolant responsibly, then refill with the approved coolant type and bleed the system to remove air. After installation, verify there are no leaks and that operating temperature remains within specification.
Marine Applications
Marine conversions that use automotive-style engines may specify an engine-mounted water pump such as this model. However, confirm suitability for closed-loop heat-exchanger systems and check clearance to marine accessories. If the engine uses a seawater pump as primary circulation, retain that pump and use this unit only where specified.
