Upgrade Your HEMI Thermostat Replace your OEM Dodge or Chrysler 195 degree thermostat with this more efficient 180 degree Jet Thermostat. Unlike your factory unit, which blocks your coolant supply, Jet's Stainless Steel Thermostat provides the engine with consistent cooling circulation. This results in lower engine temperatures, reduced strain on engine components, longer HEMI engine life, and a denser air fuel mixture.
