Mishimoto low-temperature thermostat and cast-aluminum housing is a direct-fit replacement for 2003–2007 Ford 6.0L Powerstroke engines, activating at 185°F versus the factory 192°F to allow earlier coolant flow and lower operating temperatures. The aluminum housing resists rust and is supplied with the pre-installed low-temperature thermostat. It’s targeted at drivers in warm climates or heavy-duty towing conditions and includes Mishimoto’s Lifetime Warranty.
