Vehicle identification numbers

Vehicle Identification Number (VIN)

The Vehicle Identification Number (VIN) is crucial for identifying your car. It’s stamped on a plate located on the left side of the dashboard and can be easily viewed through the driver’s side of the windshield (see illustration). You’ll also find the VIN on the Vehicle Certificate of Title and Registration. This unique number provides key details about your vehicle, including its manufacturing location, production date, model year, and body style.

Body identification plate

The Body Identification Plate is usually located on the top of the radiator support or the upper surface of the fan shroud. Like the VIN, it contains vital information about the vehicle’s production and original factory specifications. This plate is especially useful for accurately matching the vehicle’s original paint color and type during repairs, ensuring a seamless restoration.

Service parts identification label

This label is located in the trunk, usually either on the inside of the trunk lid or on the spare tire cover. It lists the VIN number, wheelbase, paint number, options, and other information specific to the vehicle it’s attached to. Always refer to this label when ordering parts.

Engine identification numbers

The engine code number on the 2.2 liter and 2.5 liter four-cylinder engine is stamped on a pad on the radiator side, at the rear of the block. The 2.3 liter OHC (Quad-4) engine VIN number is stamped into the rear of the block, near the starter motor. The Quad-4 engine also has a code label attached to the rear edge of the timing belt housing. On V6 engines, the code number is found on a pad on the rear of the block, just above the starter motor. On the 3800, the number is also stamped on a pad adjacent to the water pump.

Automatic transaxle number

The nameplate/ID number on the THM 1 25C/3T40 transaxle is attached to the upper surface of the case, near the rear (see illustration). On the 440-T4/4T60-E and 4T65-E transaxle, the transaxle VIN number is stamped into the right rear of the housing; a unit number label is attached above it.

Vehicle Emissions Control Information label

This label is found in the engine compartment.
