ACDelco Water Pumps help your engine keep its cool. Our water pumps are built with high-quality, coated seals and a steel hub and have clearly visible quality-inspection marks and GM OE appearance. Produced for just about every vehicle on the road today, these water pumps are engineered for the right fit. Stringent and multiple tests help to eliminate leaking or failing.

ACDelco Water pumps offer the latest OEM design in either aluminum or cast iron.

ACDelco pumps use new cast iron or die cast aluminum housings and feature permanently lubricated bearing and shaft assemblies.

 • Uniform wall sections and smooth coolant flow cavities.
 • Heat treated cast iron or steel stamped impellers with precisely positioned fan hub.
 • The all-aluminum casting is pressure-tested for leaks prior to pump assembly.

Additional leak testing on the assembly line helps eliminate the possibility of leakage or pump failure, offering a high degree of dependability.
