The serial number of your Land Rover can come in handy. Some Land Rover parts require the engine number and can not be acquired without it.

The serial number is stamped on a cast pad on the cylinder block. Look on the left side of the engine between the two center exhaust ports (numbers 3 and 5). There you will find the engine serial number. The engine compression ratio is also stamped above the serial number.

On some Land Rovers, the air flow meter may be in the way, obstructing your view of the serial number. The air flow meter may need to be disconnected and/or removed. However, if you have a flashlight and the right angle, you should be able to find the engine serial number.

Once the serial number is determined, use the chart below to find even more information about your Land Rover. Take the number/letter combination of the first three digits of the serial number and plug into the chart.
