The engine number of a car is generally located near the spark plugs on the left side of the engine. The exact position may vary slightly depending on the vehicle model. Information contained in the engine number: The sequence and content of the engine number may differ among manufacturers. Typically, it includes the engine model, production date, and a randomly assigned serial number given when the engine comes off the production line. Some may also include a place of origin code. Uniqueness of the engine number: The uniqueness of the engine number ensures traceability, allowing manufacturers to track and obtain feedback when engine issues arise or during investigations.
When I first looked for the engine number of my Trailblazer after buying it, it took me some time to figure it out. It's usually located on the engine block, towards the front of the car. After opening the hood, you can see it by crouching down or using a flashlight. Some models have it engraved on the metal surface, while others have a label or nameplate. I needed this number for vehicle registration at the time, so I personally went to the garage to check. If you can't find it, don't worry—you can look for a copy on the vehicle registration certificate or insurance contract. Safety tip: Make sure the engine is cool before you start, and avoid touching hot parts. It's advisable to wear work clothes or gloves to prevent oil stains on your clothes. Take a quick look during regular maintenance checks—it'll make future repairs much easier. If you can't find it, consider taking a photo for easy reference later.
