Vehicle Certification Label



The eighth VIN position identifies the engine. This is important since many parts books require the engine VIN to correctly identify the engine. For example, this two 3.8L engines are used; A VIN K engine and a VIN 1 engine. The VIN K engine is normally aspirated while the VIN 1 engine is supercharged. Knowing the correct VIN of the engine is key to getting the correct replacement parts.

Vehicle Identification Number



The Vehicle Identification number (VIN) plate is located on the left upper instrument panel and is visible from the outside of the vehicle at the lower left (driver-s side) of the windshield. The VIN consists of 17 characters. Each sequential build unit number is prefixed by eleven letters and numbers. These numbers are an important source of identification for your vehicle and its equipment. The fourth and fifth positions of the VIN identify the model (series, this case, W-Body) and body style of the vehicle. The eighth digit is the engine code and the 10th letter represents the model.
