Description
Optimized Cooling Performance. The Mishimoto Low-Temperature Thermostat is a performance upgrade for the 2018 to 2026 3.6L Jeep Wrangler JL, designed to open at 180°F—15°F lower than the factory thermostat. This earlier activation allows coolant to circulate sooner, improving temperature regulation under load, during off-road use, or in hot climates. It's ideal for drivers who demand more from their cooling systems during towing, rock crawling, or trail adventures.
Construction and Appearance. Featuring a high-quality wax construction and durable aluminum housing, this thermostat replaces the stock plastic unit known to degrade over time. The aluminum body resists warping and cracking, while the internal components ensure precise, reliable operation. The robust design offers peace of mind in extreme environments and high-performance situations.
Installation. The thermostat is a direct-fit replacement that installs easily using standard tools. No special modifications are required, making it suitable for DIYers and professionals alike.
Warranty. Backed by the Mishimoto Lifetime Warranty for long-term reliability and confidence.
Application. This Mishimoto Low-Temperature Thermostat fits 2018 to 2026 Jeep Wrangler JL models equipped with the 3.6L engine.
