Water Neck Proline LS Engine

The Vintage Air Water Neck Proline LS Engine is a precision-engineered coolant distribution component designed specifically for GM LS-series engine swaps and high-performance LS1/LS2 builds. This 90-degree swivel water neck features polished aluminum construction and delivers superior flow management while maintaining the clean aesthetic demanded by modern engine bay setups. The included gasket ensures a leak-free seal right out of the box, eliminating the need for separate sourcing.

Built from aluminum with a polished finish, this water neck combines durability with visual appeal—a critical consideration in modern engine compartments where exposed cooling components are fully visible. The 90-degree configuration accommodates tight engine bay layouts common in LS swaps into older platforms, while the swivel design provides flexibility in radiator hose routing without requiring custom fabrication. Weighing just 0.56 lbs, it adds negligible mass while maintaining structural integrity under sustained cooling system pressure.

This component is essential for enthusiasts performing LS engine conversions into second-generation F-bodies, early Camaros, or custom chassis builds where factory cooling ports require adaptation. The Proline series from Vintage Air is engineered to OEM tolerances, ensuring proper coolant circulation and preventing air pockets that compromise heat transfer. Builders who demand reliability without compromise select this water neck as part of a complete cooling system upgrade.

LS-series engines demand precision cooling solutions, and generic aftermarket fittings often create clearance issues or poor flow dynamics. This OEM-quality water neck eliminates guesswork and pairs seamlessly with Vintage Air's complete cooling product line, giving builders confidence in their thermal management strategy.
