Aluminum Water Pump - AMC V8

The Aluminum Water Pump by Milodon (MPN 16271) is a high-volume mechanical water pump engineered specifically for AMC V8 engines. Built for serious engine builders and enthusiasts who demand reliable cooling performance in street, strip, and high-performance applications, this pump delivers the flow capacity needed to maintain optimal coolant circulation under sustained load. Whether you're running a restored muscle car, a modified Jeep V8 conversion, or a competition engine, this aluminum construction offers weight savings and durability over traditional cast-iron alternatives.

Constructed from lightweight aluminum, the Milodon water pump features a high-volume impeller design that maximizes coolant flow to prevent hot spots and vapor lock—critical advantages during heavy throttle or prolonged operation. The 5/8-inch pilot and 1-3/4-inch inlet are precision-sized to match OEM AMC V8 mounting and intake manifold specifications, ensuring proper belt alignment and hose compatibility without modification. Aluminum construction reduces parasitic load on the serpentine belt system while improving heat dissipation characteristics compared to traditional cast designs, contributing to overall engine efficiency and longevity.

This Milodon aluminum water pump is ideal for owners of AMC V8 platforms—including Jeep CJ and Wagoneer V8 swaps, AMC Javelin, Ambassador, and Hornet restorations, as well as custom engine builds. The mechanical (belt-driven) design eliminates electric pump complexity and integrates seamlessly with original or period-correct cooling systems. Installation requires no special modifications when used with compatible AMC V8 blocks and intake manifolds. For builders seeking reliable high-flow cooling without added weight, this pump represents a proven solution that balances performance, authenticity, and engineering integrity.
