This AN4 stainless steel LS coolant crossover steam vent kit resolves those bottlenecks by providing a direct, organized path for trapped steam and air. Constructed with heavy-duty stainless steel AN4 tubing and precision-threaded aluminum adapters, it mounts securely to the front cylinder head while maintaining proper radiator cap function and preventing vapor lock in high-output builds.\u003c\/p\u003e \u003ch2\u003eBenefits \u0026amp; Practical Tips\u003c\/h2\u003e\n\u003cul\u003e\n\u003cli\u003ePre-engineered four-port manifolds eliminate guesswork during routing, saving hours of custom fabrication during LS engine swaps.\u003c\/li\u003e\n\u003cli\u003eTapered pipe threads create a tighter mechanical seal than straight cuts, significantly reducing the risk of slow coolant weeps at connection points.\u003c\/li\u003e\n\u003cli\u003eAlways torque fittings to manufacturer recommendations rather than over-compressing them, and consider wrapping the stainless lines with silicone braided jackets if they run close to exhaust headers.\u003c\/li\u003e\n\u003c\/ul\u003e \u003ch3\u003eTechnical Specifications\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003eLine Material: Stainless Steel\u003c\/li\u003e\n\u003cli\u003eFitting Material: Aluminum Alloy\u003c\/li\u003e\n\u003cli\u003eConnection Type: AN4 Tapered Thread\u003c\/li\u003e\n\u003cli\u003eEngine Compatibility: LS1, LS2, LS3, LS6, LS7, LS9, LSX Series\u003c\/li\u003e\n\u003cli\u003eSystem Weight: 0.5 kg\u003c\/li\u003e\n\u003cli\u003eCountry of Origin: China\u003c\/li\u003e\n\u003c\/ul\u003e \u003ch3\u003ePackage Includes\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003e5x Center Manifold Ports\u003c\/li\u003e\n\u003cli\u003e1x Corner Manifold Port\u003c\/li\u003e\n\u003cli\u003e4x Hose Couplers\u003c\/li\u003e\n\u003cli\u003e9x Hose End Fittings\u003c\/li\u003e\n\u003cli\u003e4x Hose Spike Clips\u003c\/li\u003e\n\u003c\/ul\u003e \u003cp\u003e\u003cstrong\u003eInstallation Warning:\u003c\/strong\u003e Never attempt to disconnect hoses or remove fittings while the cooling system is warm.
