MMTS-JGC-99L

The Mishimoto Low Temp Thermostat is engineered for vehicles with 3.7L PowerTech and 4.7L PowerTech engines, providing superior cooling efficiency and engine protection. Opening at 180°F (82°C), compared to the standard 195°F (90.5°C), it allows coolant to flow through the engine sooner, maintaining lower operating temperatures and preventing heat-related stress. Digitally calibrated with high-quality wax, this thermostat ensures precise and consistent operation while including a gasket for seamless, direct-fit installation. Ideal for both daily driving and heavy-duty use, it maintains optimal engine temperatures under a variety of conditions, enhancing performance, reliability, and engine longevity. As with all Mishimoto products, this racing thermostat is backed by a Lifetime Warranty, giving peace of mind for long-term use.
