Mishimoto engineers know you love your Nissan which is why We've developed a line of Titan XD performance parts. A defective thermostat can result in engine overheating and potential internal damage. Improve the reliability of your 5.0L cooling system with the Mishimoto Titan XD 5.0L Cummins High-Temperature Thermostat! This thermostat is designed as a direct-fit replacement for your factory unit. The Mishimoto thermostat has a higher activation temperature (205F) compared to the factory thermostat (200F). The higher activation temperature restricts coolant flow longer to allow a quicker engine warm-up, making this thermostat ideal for use in cold climates. As with all our Titan XD performance parts, this thermostat includes the Mishimoto Lifetime Warranty, ensuring superior product quality and craftsmanship. Whether your Titan XD is factory or modified, trust Mishimoto and our line of Titan XD performance parts to keep your 5.0L Cummins cool.
