This Mishimoto low-temperature thermostat helps lower engine temps in Dodge Ram trucks with the 5.9L Cummins, improving heat management under heavy load.
Designed for performance-focused diesel applications, the Mishimoto thermostat opens earlier than the stock unit—providing more consistent cooling, particularly during towing, hauling, or high-output conditions. It’s a direct-fit solution for Dodge Ram models using the 5.9L Cummins engine, built for reliability and cooling precision.
Key Features:
Lower Activation Temperature: Opens at 180°F vs. higher OEM temps, aiding in earlier coolant circulation and reduced engine heat.
Engineered for 5.9L Cummins: Designed to fit Dodge Ram trucks equipped with the 12-valve and 24-valve 5.9L engines from select model years.
Improved Cooling Efficiency: Helps prevent heat soak and reduces thermal stress on engine components under load.
Direct OEM Replacement: Installs easily in place of the factory thermostat without modification.
Durable Construction: Built with long-lasting materials to withstand diesel engine temperatures and pressure cycling.
Supports Heavy-Duty Use: Ideal for towing, off-road driving, or any high-performance application requiring tighter temperature control.
Whether you're maintaining a workhorse or optimizing a modified diesel truck, this thermostat gives you an edge in thermal performance and engine protection.
