      Features, Description, Q&A, Specs & Installation

      Features

      • Opens 15°F lower than stock for earlier coolant flow and improved cooling efficiency
      • Ideal for demanding conditions such as towing, off-roading, and driving in hot climates
      • Replaces failure-prone plastic housing with durable aluminum

      Description

      Don’t let a weak thermostat housing cut your adventure short. The Mishimoto Low-Temp Thermostat with Housing for the 2018+ Jeep and Ram 3.6L Pentastar replaces the stock plastic housing with a robust aluminum unit, eliminating a common failure point that can lead to leaks and overheating.--Engine protection starts with temperature control, and this thermostat is designed to keep your Jeep running cool under pressure. By opening at 180°F, which is 15 degrees earlier than the factory 195°F unit, it allows coolant to circulate through the system sooner, helping to prevent overheating and maintaining lower coolant temperatures. Whether you are crawling over rocks, towing heavy loads, or exploring in hot climates, this thermostat ensures your cooling system stays one step ahead.--Built with high-quality wax for consistent, dependable operation, this thermostat is engineered for performance and longevity. Like all Mishimoto products, it is backed by our Mishimoto Lifetime Warranty for complete peace of mind.
