Where is the Wrangler engine serial number located?

You can find it on the nameplate next to the battery under the car's hood. Like the VIN code, the engine number is unique and serves the purpose of ensuring traceability for the engine, allowing tracking in case of issues or manufacturer investigations. Here is additional information: Engine number: The sequence and content of engine numbers vary by manufacturer. Generally, they include the engine model, production date, and a randomly assigned serial number when the engine comes off the production line. Some may also include a place-of-origin code. The number of digits in the engine number differs by brand, with common engine numbers typically ranging between 7 and 8 digits.
I've been driving a Wrangler for many years. The engine serial number is usually engraved on the engine block, typically found below the intake manifold or on the side of the block. When working on DIY repairs, you'll need to open the hood first. After ensuring the engine has cooled, gently wipe away dust and oil stains with a cloth, then carefully look for the alphanumeric combination. Some model years may have slightly different locations—older models might position it near the oil pan, while newer ones tend to place it closer to the top. This is crucial because the number is needed for vehicle transfers or authenticity verification, especially after off-roading when dirt can obscure it. Keeping a flashlight handy helps. If you can't find it, don't panic—try cleaning the engine area first. If it's still missing, visit a professional shop promptly to avoid damaging parts. Regular maintenance and cleanliness can save you a lot of hassle.
