Keep engine temperatures under control with the Mishimoto Jeep Wrangler JK 3.6L Thermostat with Housing, Part MMTS-WRA-12V2. Designed as a direct-fit replacement, this thermostat regulates coolant flow to support efficient warm-up, consistent operating temperatures, and reliable engine performance. Its lower-temperature activation point allows coolant to circulate earlier than the factory thermostat, helping manage heat during demanding driving conditions.
The Mishimoto thermostat activates at 180°F compared with the factory 203°F setting. Earlier coolant flow helps reduce and maintain lower engine coolant temperatures, making this upgrade well suited for warm climates, towing, off-road use, and other extreme driving applications. The included aluminum housing provides enhanced durability, while the galvanized steel bleeder screw helps resist corrosion and supports proper cooling-system service.
Constructed with high-quality wax, the thermostat is engineered for reliable and repeatable operation. The precise-fit design supports straightforward installation and dependable coolant regulation for compatible Jeep and Dodge applications. Each Mishimoto thermostat is backed by the Mishimoto Lifetime Warranty, providing long-term assurance of product quality and craftsmanship. Verify vehicle compatibility before installation, and follow the manufacturer's recommended cooling-system service procedures.
