Mishimoto Low-Temp Thermostat with Aluminum Housing - 82°C (180°F) for 2018+ Jeep Wrangler JL / 2020+ Gladiator 3.6L

Don’t let a weak thermostat housing cut your adventure short. The Mishimoto MMTS-MOP-18L Low-Temp Thermostat with Aluminum Housing replaces the failure-prone stock plastic housing on the 2018+ Jeep Wrangler JL and 2020+ Gladiator (3.6L Pentastar) with a robust billet aluminum unit. Opening at 180°F (15°F earlier than the factory 195°F unit), it allows coolant to circulate sooner, keeping temperatures lower under load, towing, off-roading, or in hot climates. Includes everything needed for a complete, leak-free install and is backed by Mishimoto’s Lifetime Warranty.

Key Features

  • Durable Aluminum Housing: Eliminates the common plastic housing failure point and leaks
  • Low-Temp Thermostat: Opens at 180°F (15°F earlier than stock) for improved cooling efficiency
  • Ideal for Demanding Use: Perfect for towing, off-roading, and high-heat environments
  • Complete Kit: Includes thermostat, housing, gasket, temperature sensor, and O-ring
  • Direct Bolt-On Replacement: No modifications required
  • Mishimoto Lifetime Warranty: Complete peace of mind on every install
