Fleece Performance 89-98 Dodge 2500/3500 5.9L 12V Cummins Replacement Heater Core Line Kit

The Fleece Performance 89-98 Dodge 2500/3500 5.9L 12V Cummins Replacement Heater Core Line Kit is a high-quality upgrade designed to replace leaking or corroded heater tubes in Dodge trucks equipped with the 5.9L 12V Cummins engine. Constructed with stainless steel and high-temperature silicone hoses, this kit provides a durable and reliable solution for restoring heater line functionality from the engine block to the firewall. It includes stainless steel heater tubes that replace OEM parts, silicone hoses for straight and 90-degree connections, and billet aluminum clamps and standoffs for secure mounting. This comprehensive kit ensures a direct replacement, offering improved durability and performance over factory components.

Designed for 1989–1998 Dodge Ram 2500 and 3500 models originally equipped with air conditioning, this kit is intended as a bolt-on upgrade for trucks with factory heater lines. It is compatible with vehicles that have the stock or aftermarket manifolds, though some applications may require trimming hoses or additional mounting brackets, especially if an aftermarket exhaust manifold is installed. The kit includes all necessary components for installation, excluding hoses for non-air-conditioned trucks, which must be supplied separately. Ideal for restoring heater performance and preventing leaks, this kit is suitable for daily driving, towing, and off-road use.
