Pontiac H/V Aluminum Water Pump

The Pontiac H/V Aluminum Water Pump by MILODON is a high-volume mechanical cooling solution engineered for Pontiac V8 engines demanding superior heat dissipation and reliable circulation. Built for enthusiasts and professional builders who refuse to compromise on engine cooling performance, this pump delivers the flow capacity necessary to maintain optimal operating temperatures under sustained driving conditions. Whether you're restoring a classic Pontiac muscle car or upgrading cooling efficiency in a performance build, the H/V designation indicates high-volume operation—essential for engines generating significant heat load.

Constructed from durable aluminum, the Pontiac H/V Aluminum Water Pump reduces weight while maintaining structural integrity and thermal conductivity. The 5/8-inch pilot shaft ensures precise OEM-style fitment and compatibility with standard Pontiac V8 engine blocks and accessory drive systems. MILODON's mechanical design uses proven impeller geometry to maximize coolant displacement per engine revolution, reducing cavitation and ensuring consistent flow rates across the entire RPM range. The natural aluminum finish resists corrosion while allowing easy visual inspection of internal wear patterns, and the compact 8.5 × 8.3 × 10.9-inch envelope fits within tight engine compartment constraints without sacrificing performance.

Pontiac V8 owners—from street-driven classics to high-RPM race engines—benefit from the reliability and increased flow capacity this pump provides. Installation requires standard mechanical pulley alignment and belt tension adjustment; the 5/8-inch pilot accepts factory or aftermarket crankshaft pulleys without modification. At 5.6 lbs, the lightweight aluminum construction contributes to overall underhood balance while the high-volume design prevents hot spots and coolant cavitation that plague undersized OEM pumps during aggressive driving or towing. Verify pilot diameter and belt drive configuration match your specific Pontiac V8 engine year and application before purchase.
