Location of numbers of power units
Product improvement is a continuous process of any in-line production. At the same time, with the exception of cases of major changes in the design of models coming off the assembly line, the results of the modification process are not covered in the vehicle manual. However, the manufacturer draws up numbered lists of manufactured spare parts, which is why the information encoded in the vehicle identification numbers is of particular importance when buying the latter. When placing an order for the required spare part, try to provide the seller with as much information about your car as possible. Be sure to provide the model name, year of manufacture, as well as body and power unit numbers.
Vehicle identification number (VIN)
This extremely important number is engraved on the rear bulkhead of the engine compartment, as well as on the nameplate attached to the instrument panel under the windshield on the driver's side of the car. VIN is also entered in the vehicle registration certificate and registration certificate.
The number encodes information about the date and place of manufacture of the car, the year of manufacture of the model, as well as the type of body. In addition, the VIN is indicated on the certification sticker located at the bottom of the driver's door pillar of the car.
Engine code and model year
The two main components of a VIN are the engine and model year codes.
The engine code is determined by the sixth position of the number, counting from left to right. The model year code is contained in the first position of the VIN after the asterisk in its central part. In this case, the following relations take place:
Engine code:
- 5 = F23A1
- 6 = F23A4
- 7 = F23A5
- 8 = J30A1
Model year code:
- W = 1998
- X = 1999
The engine code is usually specified when ordering spare parts for the power unit. Separately from the VIN, as part of the power unit number, this code is also located on the right (passenger) side of the power unit, near the exhaust manifold on 4-cylinder models, or under the starter on V6 models. The engine code is the first five digits of the number and is decoded as follows:
On 4-cylinder models, the engine code is located near the exhaust manifold
On V6 models, the engine code is stamped on a nameplate attached to the left front corner of the cylinder head
- F23A1 = 4-cylinder, 16-valve, 2.3L SOHC engine equipped with VTEC
- F23A4 = 4-cylinder, 16-valve, 2.3L SOHC engine equipped with VTEC
- F23A5 = 4-cylinder 16-valve 2.3L SOHC engine
- J23A1 = 6-cylinder V-6 24-valve 3.0L SOHC engine
Transmission number
This number is usually required when ordering transmission line repair parts. On models equipped with a manual transmission, the transmission number is stamped on the clutch dome, next to the starter. On models with AT, the number is located on the right in front of the transmission housing, near the dipstick.
