Jaguar Engine Number

Jaguar Engine Number

Jaguar is a luxurious car brand known for its powerful engines and sleek designs. The Jaguar engine is the heart of the car, and it is important to understand how to identify and maintain it. One crucial aspect of Jaguar engine identification is the engine number. In this article, we will discuss what a Jaguar engine number is, why it is important, and how to find and decode it.

What is aJaguar Engine Number

A Jaguar engine number is a unique identification number assigned to each engine that Jaguar manufactures. It is a series of alphanumeric characters that provide information about the engine, such as the model, year of production, and manufacturing location. The engine number is typically located on the engine block and can be used to identify the engine in case of repairs, maintenance, or replacement.

The engine number is essential for several reasons. Firstly, it helps to identify the engine and ensure that the correct replacement parts are used in case of repairs or maintenance. Different Jaguar models may have different engine configurations, and using the wrong parts can result in poor performance or even damage to the engine. Secondly, the engine number can help to authenticate the vehicle’s history. The engine number can be cross-referenced with the vehicle’s registration documents to verify its origin, ownership, and maintenance history. This information can be helpful for buyers when purchasing a used Jaguar car.

Lastly, the engine number can provide information about the engine’s specifications and production history. By decoding the engine number, one can determine the engine’s displacement, compression ratio, and other technical details. This information can be useful for Jaguar enthusiasts or collectors who want to know more about their vehicle’s history.

It is not possible to identify a particular vehicle using the engine number, but, a Jaguar VIN enquiry to the importer/dealer can result in the engine number of a particular vehicle being identified.

Jaguar Engine Number Location

Finding and decoding your Jaguar engine number is relatively straightforward. The engine number is typically located on the engine block, either on the top or side of the block, near the cylinder head. The exact location of the engine number may vary depending on the Jaguar model and year of production. However, it is usually stamped onto the engine block and can be identified by its unique alphanumeric characters.

Appearance of the Jaguar Engine Number

The engine number is stamped or needle-punched onto a smoothly ground spot on the engine block. In addition a small, separate metal plate can also be screwed onto the engine (V6 Diesel engine, R4 2.2 litres Diesel engine).

It is often extremely difficult to read the engine number because of its position on the engine and the engine covering as well.

1 = Date: May 15 2006
2 = Time: 09:53:24

The engine number on all V8 engines comprises the date and time of production. The moment when the engine block arrives on the conveyor and the engine construction begins is taken as the time.
The date can either be in DDMMYY or YYMMDD format. The time frequently contains seconds as well as hours and minutes.

Thus, for example, engine number 980904 0147 corresponds to the date of production 04.09.1998; at 01:47.

Some engine numbers have a suffix

Example: – 42 8 PS (4.2 litre 8 cylinder, HP = patrol supercharged = compressor)

– 44 8 PN (4,4 Liter 8 Zylinder, PN = patrol normal aspirated = aspirated engine)

Starting model year 2010, a 5-digit consecutive number has been used (instead of the time when construction was started), e.g.


1- Production date in YYMMDD format (090721 = 21 July 2009)

2- consecutive number

3- Engine capacity/displacement (50 = 5.0 litre / 42 = 4.2 litre)

4- Number of cylinders (8 = 8 cylinders)

5- Type of fuel (P = petrol)

6- Type of engine (N= naturally aspirated engine / S = supercharged [SC] compressor)

Older V6 petrol engines and 4-cylinder engines are made in the Cleveland engine plant. The engine numbers for inline 4-cylinder engines and V6 engines have a different code. They begin with a serial number, followed by a code for the type of engine and transmission (Example: 401 stands for a 3.0 litre automatic and 402 stands for a 3.0 litre manual transmission engine).


1- Consecutive number
2- Engine/transmission type
3- Engine capacity/displacement (22 = 2,2 litre)
4- Number of cylinders (4 = 4-cylinders)
5- Typ of fuel (P = petrol, D = Diesel)
6- Type of engine (T = Turbo / N= normal aspirated engine / S= supercharged [SC] compressor)

In conclusion, understanding the importance of the Jaguar engine number is crucial for maintaining and authenticating your Jaguar vehicle. The engine number provides valuable information about the engine’s specifications, production history, and authenticity. By knowing how to find and decode your Jaguar engine number, you can ensure that your vehicle receives the proper maintenance and repair, and verify its history when buying or selling.
