* Visually: The most straightforward method is to open the hood and look at the engine block. The displacement (3.5L or 2.7L) will usually be cast directly onto the engine block itself. Look for a prominent number sequence that includes "3.5" or "2.7". It might be near the oil filter or the front of the engine.
* Check your vehicle documentation: Your owner's manual or the vehicle identification number (VIN) decoder (available online through various sources, including the manufacturer's website) will definitively state the engine size.
If you can't find it visually or in the documentation, you might need to consult a mechanic or a Dodge dealership. They can easily identify the engine type with a VIN check.
