The Mishimoto low-temperature thermostat for Dodge 5.9L and 6.7L Cummins engines is a direct-fit replacement that opens at 180°F, lower than the factory units. Earlier coolant flow helps reduce and maintain lower engine temperatures, making it suitable for warm climates or heavy towing and severe-duty use. The thermostat is backed by Mishimoto's Lifetime Warranty to support long-term reliability.
