Note: This thermostat housing replaces the Ford Motorcraft RT-1169 thermostat.

Stop leaving your 6.0L Powerstroke’s cooling system to chance. A defective thermostat can quickly lead to overheating and costly engine damage. The Mishimoto High-Temperature Thermostat with CNC 6061 aluminum housing keeps your truck running hotter, longer, and safer. With a higher activation temperature of 200°F, this thermostat restricts coolant flow for faster engine warm-up, perfect for cold climates or heavy-duty towing. Built tough and designed as a direct-fit replacement, it’s a no-compromise upgrade for serious Powerstroke owners.
