Constructed with durable braided nylon hose, high-temperature sleeves, and AN fittings, the kit ensures a leak-free installation and long-lasting performance. Its OE fit-and-finish guarantees seamless integration with your vehicle, making it an essential addition for enhancing reliability and longevity of the cooling system on your Cummins-powered truck.

It addresses common coolant flow issues that can lead to catastrophic engine damage, especially in the rear cylinders. The kit includes rear and front coolant bypass thermostat housings, new EGR crossover tube gaskets, a black braided nylon coolant hose with protective high-temperature sleeve, AN fittings, and mounting hardware. Ideal for daily driving, towing, or heavy-duty use, this kit enhances cooling efficiency and helps prevent over-temperature and over-pressure conditions, ensuring your engine runs reliably under demanding conditions.
