A defective thermostat can result in engine overheating and potential internal damage. Improve the reliability of your 6.0L cooling system with a Mishimoto Ford 6.0L Powerstroke Low-Temperature Thermostat and CNC Housing! This thermostat is designed as a direct-fit replacement for your aged factory unit. The Mishimoto thermostat has a lower activation temperature (185 F) compared to the factory thermostat (192 F). The lower activation temperature allows coolant to flow through the engine earlier, which reduces and maintains lower engine temperatures. This thermostat is ideal for use in warmer climates or under extreme towing/driving conditions. The CNC machined 6061 aluminum housing will provide a proper seal and will not rust over time. Like all of our Powerstroke Performance parts, this thermostat and housing includes the Mishimoto Lifetime Warranty. Engine coolant thermostat designed to regulate coolant flow and maintain optimal operating temperature. Ensures efficient warm-up, prevents overheating, and supports reliable performance with a precise fit. 2005 Ford F-250 Super Duty FX4 6.0 Liter TorqShift, 2004 Ford F-250 Super Duty Harley-Davidson Edition 6.0 Liter 4R100, 2006-2007 Ford F-250 Super Duty Harley-Davidson Edition 6.0 Liter 5R110W, 2004-2005 Ford F-250 Super Duty Harley-Davidson Edition 6.0 Liter TorqShift, 2004 Ford F-250 Super Duty King Ranch 6.0 Liter 4R100, 2006-2007 Ford F-250 Super Duty King Ranch 6.0 Liter 5R110W, 2004-2005 Ford F-250 Super Duty King Ranch 6.0 Liter TorqShift, 2004 Ford F-250 Super Duty Lariat 6.0 Liter 4R100, 2006-2007 Ford F-250 Super Duty Lariat 6.0 Liter 5R110W, 2004-2005 Ford F-250 Super Duty Lariat 6.0 Liter TorqShift, 2004 Ford F-250 Super Duty XL 6.0 Liter 4R100, 2006-2007 Ford F-250 Super Duty XL 6.0 Liter 5R110W, 2004-2005 Ford F-250 Super Duty XL 6.0 Liter TorqShift, 2004 Ford F-250 Super Duty XLT 6.0 Liter 4R100, 2006-2007 Ford F-250 Super Duty XLT 6.0 Liter 5R110W, 2004-2005 Ford F-250 Super Duty XLT 6.0 Liter TorqShift, 2004 Ford F-350 Super Duty Harley-Davidson Edition 6.0 Liter 4R100, 2006-2007 Ford F-350 Super Duty Harley-Davidson Edition 6.0 Liter 5R110W, 2004-2005 Ford F-350 Super Duty Harley-Davidson Edition 6.0 Liter TorqShift, 2004 Ford F-350 Super Duty King Ranch 6.0 Liter 4R100, 2006-2007 Ford F-350 Super Duty King Ranch 6.0 Liter 5R110W, 2004-2005 Ford F-350 Super Duty King Ranch 6.0 Liter TorqShift, 2004 Ford F-350 Super Duty Lariat 6.0 Liter 4R100, 2006-2007 Ford F-350 Super Duty Lariat 6.0 Liter 5R110W, 2004-2007 Ford F-350 Super Duty Lariat 6.0 Liter S6-650, 2004-2005 Ford F-350 Super Duty Lariat 6.0 Liter TorqShift, 2004 Ford F-350 Super Duty XL 6.0 Liter 4R100, 2006-2007 Ford F-350 Super Duty XL 6.0 Liter 5R110W, 2004-2007 Ford F-350 Super Duty XL 6.0 Liter S6-650, 2004-2005 Ford F-350 Super Duty XL 6.0 Liter TorqShift, 2004 Ford F-350 Super Duty XLT 6.0 Liter 4R100, 2006-2007 Ford F-350 Super Duty XLT 6.0 Liter 5R110W, 2004-2007 Ford F-350 Super Duty XLT 6.0 Liter S6-650 ...See Application Guide for Additional Fitments
