Universal LS / LT Heater Core Hose Set

The Universal LS / LT Heater Core Hose Set by ICT BILLET is a complete replacement solution for classic and modern engine swap applications requiring reliable coolant circulation between the engine block and heater core. This kit addresses a critical cooling system need in vehicles undergoing engine conversions or experiencing degraded factory heater hose lines. Designed for LS and LT engine platforms, this hose assembly ensures proper thermal management and cabin heating performance across demanding automotive builds and restoration projects.

This heater hose set features premium rubber construction rated for high-temperature coolant flow, with two distinct hose diameters to match OEM routing and connection points. The kit includes one 5/8-inch inner diameter hose and one 3/4-inch inner diameter hose, each measuring 5 feet in total length to accommodate various engine bay layouts and heater core configurations. The 90-degree fitting orientation allows for efficient directional coolant routing without kinks or flow restrictions, while the black rubber compound resists degradation from heat, pressure cycles, and chemical exposure inherent in modern coolant formulations.

Builders and technicians performing LS or LT engine swaps will benefit from this matched-pair approach, which eliminates the need to source individual hose segments and ensures compatibility across both supply and return lines. Installation is straightforward with standard hose clamps at connection points; the 5-foot length provides adequate slack for custom routing around engine accessories and chassis obstacles. This set is ideal for street rods, restorations, and performance applications where factory heater functionality must be preserved without compromise on cooling system integrity.
