The Aluminum Engine Heater Core Bypass Kit for 5/8 and 3/4 Hose (SKU 626-001) delivers a durable, easy-to-install solution for bypassing your vehicle’s heater core. Designed to replace fragile plastic fittings, this kit uses sturdy aluminum billets and a high-quality rubber hose to create a reliable bypass path. It’s compatible with most common heater hoses, giving you a practical option for maintenance, diagnostics, or temporary routing of coolant away from the heater circuit. Whether you’re working on a heater core replacement or simply testing coolant flow, this kit keeps your engine cooling system accessible and leak-free.
