Ensure optimal cooling performance with the Kustom Truck Genuine Cummins N14 Thermostat Housing, featuring a vertical (out-the-top) outlet, designed for Peterbilt and Kenworth trucks. This housing is perfect for OEM replacements or engine conversions where a donor engine has a horizontal thermostat housing, but the truck’s upper radiator tubes require a vertical configuration. Compatible with Peterbilt (e.g., 389, 388, 367) and Kenworth (e.g., W900, T800, T660), Freightliner and Western Star chassis, this genuine Cummins component ensures proper coolant flow and thermostat operation in class 8 trucks. Ideal for mechanics and fleet owners performing engine swaps, cooling system repairs, or routine maintenance, this thermostat housing guarantees compatibility and reliability.
