6.7L Powerstroke Low Temp High Flow Thermostat

The SPE 6.7L Powerstroke Low Temp, High Flow Thermostat is engineered to address high fluid temperatures in your 6.7L Powerstroke engine. If you're experiencing uncomfortably high oil temperatures during normal driving or towing, or high transmission temperatures in 2017+ models, this thermostat offers an effective solution. Compared to the stock OEM thermostat which opens at 194/201°F, the SPE unit begins opening at a lower 175/180°F. This represents a 19-21 degree difference, leading to substantial temperature reductions. The thermostat effectively lowers coolant, oil, and even transmission temperatures on 2017-2019 models, with benefits noted as up to a 30°F drop. Installation is designed to be straightforward, with an estimated time of just 15 minutes. This thermostat is specifically designed for 2011-2026 Ford SuperDuty F-250, F-350, F-450, and F-550 models utilizing the 6.7L Powerstroke engine. It's important to note the transmission cooling system difference: 2017-2019 models use the primary cooling system for transmission temperature management, while 2011-2016 models utilize a secondary system.
