The Mishimoto thermostat and housing combo is engineered to regulate coolant flow and reduce engine temperatures in the 2016–2019 Nissan Titan XD.
Designed as a direct-fit upgrade, this assembly features a preinstalled low-temperature thermostat housed in a precision-machined CNC aluminum body. The thermostat opens earlier than stock, promoting faster coolant circulation to help mitigate heat buildup—especially useful during towing or heavy-duty use. The billet aluminum housing offers improved durability over factory plastic, reducing the chance of warping or leaks over time.
Its OE-style design allows straightforward installation using the factory mounting points and coolant hose connections. Whether maintaining peak thermal efficiency or replacing a worn OEM unit, this upgrade blends performance and reliability for demanding diesel applications.
Key Features:
Lower Activation Temp: Thermostat opens at 186°F (versus stock 198°F) for improved cooling response
CNC-Machined Housing: Constructed from billet 6061 aluminum for strength and resistance to distortion
Preinstalled Thermostat: Ready-to-install assembly simplifies installation and minimizes downtime
Direct-Fit Design: Bolts up to factory mounting locations with stock hoses and sensors
Enhanced Cooling Control: Reduces the risk of overheating during towing, hauling, or extended idling
Corrosion-Resistant Finish: Anodized surface helps protect against wear and oxidation
Compatible Models: Designed specifically for 2016–2019 Nissan Titan XD with Cummins 5.0L V8 Diesel
Engineered to deliver reliable temperature regulation in high-load conditions, this thermostat and housing set helps protect vital engine components by optimizing cooling system performance.
