LS Heater Core Bypass Hose

FITTINGS247 LS Heater Core Bypass Hose – LS1 LS2 LS3 LSX LQ4 LQ9 Water Pump Coolant Crossover Delete

Simplify your cooling system with the FITTINGS247 LS Heater Core Bypass / Delete Hose, designed to suit all GM LS engines running a mechanical water pump, including LS1, LS2, LS3, LSX, LQ4, and LQ9 platforms.

This high-quality molded hose is engineered to loop the two heater hose outlets on the water pump, allowing for a clean and effective heater core delete or bypass setup. Unlike universal straight hoses, this unit features a pre-molded 180-degree bend, ensuring perfect fitment without kinking, collapsing, or restricting coolant flow.

Ideal for race cars, engine swaps, or simplified street builds, this bypass hose improves engine bay tidiness while maintaining proper coolant circulation.
