Where do I find the engine number?
While your vehicle identification number includes a lot of information, it doesn’t provide much about the engine, other than the size that originally came with the car. The engine number tells a lot more. This information is located on the engine number stamp, which can be found on the front of the engine. With the 2.5-liter engine, it’s to the right of the manifold. On the 3.5-liter engine, it’s in the same location, but the manifold is elsewhere (both are on the driver side front of the engine).
