Mishimoto 11+ Ford 6.7L Powerstroke Low-Temperature Primary Cooling Sys Thermostat

This Mishimoto thermostat activates at 189°F and 196°F, which is lower than the factory settings. This means coolant starts circulating through your 6.7L Powerstroke engine sooner, helping to keep overall engine temperatures down. A defective thermostat can lead to overheating and potential engine damage, so replacing an old one with a unit that manages heat more effectively is a smart move, especially if you live in a warmer climate or frequently tow heavy loads.

This thermostat is designed as a direct-fit replacement for your stock unit, making installation straightforward. By allowing coolant to flow earlier, it helps maintain more consistent and lower operating temperatures, which is beneficial for the longevity of your engine under demanding conditions. Consider pairing this with a Mishimoto aluminum radiator for a more complete cooling system upgrade.
