Mishimoto low-temperature thermostat for the 2018+ Jeep Wrangler JL, Gladiator and Ram 1500 3.6L Pentastar. It replaces the fragile factory plastic housing with a durable aluminum unit and opens at 82°C / 180°F — 15°F earlier than the stock 195°F unit — letting coolant circulate sooner to maintain lower temperatures while crawling, towing, or running in hot climates. Backed by the Mishimoto Lifetime Warranty.
