Notice: The radiator cap on your vehicle is a pressure-type cap and must be tightly installed to prevent coolant loss and possible engine damage from overheating. Be sure the arrows on the cap line up with the overflow tube on the radiator filler neck.

The radiator pressure cap for the 3.5L V6 engine and the 3.6L V6 engine are located in different areas of the engine compartment. See Engine Compartment Overview for more information on location.
