Upgrade your Peterbilt 379’s cooling performance with the Kustom Truck Radiator and Charge Air Cooler Tube Kit, precision-engineered for 2004 to 2007 truck chassis originally equipped with a Caterpillar engine and now fitted with a Caterpillar 3406E or C15 single turbo engine. Crafted from premium 304 stainless steel in mill or polished finish, this OEM-quality kit includes right and left charge air cooler (CAC) tubes, an upper radiator tube, and a two-piece lower radiator tube set, ensuring efficient airflow and coolant flow with corrosion resistance. Tailored for engine conversions, it features precise configurations: the right CAC tube pairs with a 4" 90-degree turbo outlet elbow (Kustom Truck P/N 99999040 or similar), the left CAC tube aligns with a 45-degree intake elbow with an upward/forward inlet (Kustom Truck P/N 99107003 or similar), the upper radiator tube fits a vertical-facing thermostat housing outlet, and the lower radiator tubes match a 3" water pump outlet. Ideal for mechanics and truck owners, this kit blends durability and style for heavy-duty diesel applications. Note: This kit is not compatible with trucks originally equipped with a Cummins CM870 ISX engine due to engine bay placement differences.
