Low Profile Water Neck Housing

The ALLSTAR PERFORMANCE Low Profile Water Neck Housing (ALL30382) is a precision-engineered cooling system component designed for high-performance Chevy V8 engines. This 90-degree water neck inlet fitting provides a low-profile design that integrates seamlessly into tight engine bay configurations while maintaining optimal coolant flow characteristics. The aluminum construction with anodized finish resists corrosion and thermal stress, ensuring reliable long-term service in demanding engine environments.

Featuring a 16 AN female O-ring inlet connection, this water neck housing accommodates AN-series hose fittings commonly used in custom cooling systems and engine swaps. The anodized aluminum finish provides superior corrosion resistance compared to bare aluminum, particularly important in street and race applications where the cooling system endures sustained heat cycles. All necessary mounting hardware is included, eliminating the need for additional fastener sourcing. The compact 5.5 × 1.75 × 9-inch footprint allows installation in space-constrained environments without sacrificing functional performance or flow dynamics.

This water neck housing serves engine builders, performance enthusiasts, and restoration specialists working with Chevy V8 platforms. Whether upgrading a stock cooling system for higher output or fabricating a custom cooling circuit for a swap application, the low-profile design solves common clearance conflicts around valve covers and accessory mounting points. The 90-degree inlet orientation provides flexible hose routing options while the AN female O-ring connection ensures leak-free performance under pressure.

ALLSTAR PERFORMANCE water neck housings are recognized across the engine-building community for precision fit and material integrity. The combination of low-profile geometry, anodized durability, and standard AN fittings makes this component a reliable choice for both street applications requiring dependable cooling management and high-output engines where thermal control is critical to longevity.
