The serial number displayed on your engine helps shops discover the parts needed to perform repairs on your vehicle. To decode and find information about your engine on your own, you can use the Internet and accomplish this swiftly.

Step 1

Find your vehicle's engine serial number. Depending on your vehicle's make, the serial number for your engine will be displayed on the left, right, back or front region of your engine block.

Step 2
