The Mishimoto racing thermostat for 3.7L and 4.7L Dodge/Jeep Hemi engines opens at a lower temperature (180°F) than standard units to circulate coolant sooner and reduce peak engine temperatures. It supports improved cooling efficiency for daily use or towing, fits the listed Jeep/Grand Cherokee Hemi applications, and is backed by Mishimoto’s lifetime warranty for long‑term confidence.
