Head Coolant Steam Port Crossover Bypass Hose

The Head Coolant Steam Port Crossover Bypass Hose by ICT Billet is an essential component for builders and enthusiasts running custom engine cooling systems, particularly in high-performance and modified applications. This hose manages coolant flow between the cylinder head's steam ports and the bypass circuit, preventing pressure buildup and coolant overflow during aggressive driving or engine modifications. Whether you're upgrading to an LS-based engine swap, installing a custom radiator setup, or tuning a turbocharged platform, this crossover hose ensures proper thermal management and eliminates factory cooling limitations.

ICT Billet's Head Coolant Steam Port Crossover Bypass Hose is precision-engineered to handle the demands of modified engine bays where OEM cooling paths no longer suffice. The hose construction is designed to withstand elevated coolant temperatures and system pressures without degradation or failure. At just 0.25 lbs and compact dimensions (13.25 inches in length with a 0.75-inch diameter), it integrates seamlessly into space-constrained engine compartments while maintaining superior flow characteristics. The bypass design allows excess coolant pressure to route safely away from sensitive components, reducing the risk of hose rupture or coolant loss that could compromise engine reliability during track sessions or dyno runs.

This component is ideal for LS engine swaps, performance radiator upgrades, and custom cooling manifold installations where OEM hoses and routing prove inadequate. Technicians and engine builders appreciate ICT Billet's attention to fitment and durability—the hose is sized and contoured to integrate with various cylinder head configurations and aftermarket water pump combinations. Installation typically requires basic hose clamp connections to existing steam ports and bypass fittings, making it accessible for both professional shops and experienced DIY builders. For anyone serious about engine reliability in modified applications, this crossover bypass hose is a critical upgrade for maintaining optimal coolant circulation and preventing pressure-related failures.
