14-23 Ram 1500 & Jeep 3.0L EcoDiesel Thermostat Housing 68253514AA

The Mopar 68253514AA thermostat and housing is the genuine OEM 3.0L EcoDiesel thermostat housing assembly for 2014-2023 Ram 1500, Jeep Wrangler, Gladiator, and Grand Cherokee diesel models. This integrated thermostat-in-housing unit regulates coolant flow and engine temperature, and it commonly gets replaced when the original housing cracks, leaks coolant, or the thermostat sticks. It comes as a complete assembly with the thermostat already in the housing.

The 68253514AA is the OEM thermostat and housing assembly for the 3.0L EcoDiesel V6, covering 2014-2023 Ram 1500 and 2014-2023 Jeep diesel models, and it ships as a complete thermostat-in-housing unit.

The One Thing That Decides Fitment

Fitment on this part is driven by the engine, not the model. The 68253514AA is the correct thermostat and housing for any covered Ram 1500 or Jeep running the 3.0L EcoDiesel V6, but it does not fit gas models. If your truck or Jeep is a gas V6 or V8, this is the wrong part regardless of year.

Buy this assembly to restore stock EcoDiesel cooling across the Ram 1500, Wrangler, Gladiator, and Grand Cherokee diesel lineups. The thermostat comes already installed in the housing, so confirm your engine is the 3.0L diesel, then this is the right assembly to order.

What This Assembly Does

The thermostat regulates coolant flow to hold the 3.0L EcoDiesel at its proper operating temperature, and on this engine it lives inside an integrated housing. When the housing cracks or the thermostat sticks, you can see coolant leaks, overheating, or an engine that never reaches full temperature. Replacing the complete assembly restores the factory cooling function in one part instead of chasing a separate thermostat and a separate housing.

Because it is a genuine Mopar OEM unit, it matches the factory fit and function with no modification. This is the part to order for a clean, stock-style cooling repair.

Avoid These Common Mistakes
