Water Neck Housing Ford w/ -16an Fitting

The Water Neck Housing Ford w/ -16AN Fitting is a precision aluminum coolant distribution component engineered for small-block Ford engine builders and performance enthusiasts. This 35-degree water neck serves as the critical junction point where the upper radiator hose connects to the engine block, managing coolant flow under high-pressure conditions. Whether you're rebuilding a street engine, prepping a track vehicle, or restoring a classic, this bolt-on housing ensures reliable thermal management and straightforward installation without requiring extensive machine work.

Manufactured by U-B Machine from billet aluminum and finished in blue anodize, this water neck housing delivers both durability and corrosion resistance in high-heat engine environments. The -16AN male fitting accepts industry-standard braided hose or hard-line cooling systems, allowing flexibility in custom plumbing layouts. The 35-degree angle optimizes hose routing in tight engine bays while minimizing stress on connection points. Blue anodized construction protects against oxidation and galvanic corrosion, critical for longevity in direct water contact applications. Compact dimensions (3.25 x 2.2 x 3.35 inches) ensure fitment in space-constrained installations without interference with accessory brackets or valve covers.

Small-block Ford owners—from 221 to 351 cubic-inch platforms—benefit most from this bolt-on water neck when transitioning to aftermarket cooling systems or custom engine bays. The -16AN fitting standard integrates seamlessly with modern braided coolant lines, radiant cooling kits, and remote thermostat housings, making it essential for street rods, engine swaps, and competition builds. Installation is straightforward: simply bolt to the engine block and attach your radiator hose via the -16AN port. Weighing just 0.42 pounds, this component adds minimal mass while providing years of leak-free operation in both street and motorsport applications.
