  Description

  The Mopar 5184651AJ Thermostat is supplied as a complete thermostat housing assembly with the thermostat pre‑installed. This unit regulates engine coolant flow to ensure the engine reaches and maintains proper operating temperature. When the engine is cold, the thermostat restricts coolant flow; once operating temperature is reached, it opens to allow circulation through the radiator, preventing overheating and promoting efficient combustion and emissions control.
