4 to 1 Coolant Manifold #12an to 1.50in Hose

The 4 to 1 Coolant Manifold #12AN to 1.50in Hose by MEZIERE is a high-flow cooling distribution component engineered for high-performance vehicles requiring integrated coolant management across multiple circuits. This manifold consolidates four separate coolant lines into a single outlet, eliminating complex plumbing configurations while maintaining thermal efficiency under sustained demand. Purpose-built for engine builders, motorsport competitors, and performance technicians, this component simplifies custom cooling system architecture on race engines, truck applications, and heavily modified street platforms.

The 4 to 1 configuration features #12AN port inlets and a 1.50-inch hose outlet, facilitating seamless integration with custom coolant lines and radiator return circuits. MEZIERE manifolds are manufactured from aluminum construction with internal porting optimized to minimize turbulence and pressure drop across the junction. The #12AN SAE fittings are industry-standard for performance cooling systems, compatible with braided stainless steel hose and both push-lock and -AN adapter fittings commonly used in technical engine bays. Compact dimensions (4.3 x 4.3 x 7.7 inches) allow mounting in tight underhood spaces typical of mid-engine or transverse powerplant installations.

Professional-grade mechanics, drag racing teams, and drift circuit competitors benefit most from this manifold's ability to consolidate coolant flow while preserving system pressure integrity. Installation requires basic SAE wrench work and hose routing familiarity; -AN fittings should be torqued to manufacturer specification to prevent weeping at load. Compatibility spans custom cooling loops on LS, Coyote, and import performance builds where factory manifolds restrict flow or occupy critical engine bay real estate. Verify your existing hose specifications and fitting orientation before ordering to ensure drop-in fitment with your current coolant circuit design.
