How do I find out what engine my Chevy truck has?

If you own a Chevy truck, it's important to know the details of the engine that powers your vehicle. This information can be useful for maintenance, repairs, or if you're considering upgrading or modifying your truck. Here's a step-by-step guide on how to find out what engine your Chevy truck has.


Check the VIN Number


The easiest way to determine the engine in your Chevy truck is to look at the Vehicle Identification Number (VIN). The VIN is a unique 17-digit code that contains information about your vehicle, including the engine type. You can typically find the VIN on the driver's side dashboard, the driver's side door jamb, or in the owner's manual.



  • Locate the VIN on your Chevy truck

  • Decode the VIN to find the engine information

  • The 8th digit of the VIN will indicate the engine code


Once you have the VIN, you can use an online VIN decoder or refer to a VIN decoding guide to determine the engine specifications for your Chevy truck.


Look for Engine Identification Markings


Another way to find out the engine in your Chevy truck is to look for identification markings on the engine itself. These markings are usually located on the engine block, cylinder head, or other visible components. Common engine identification markings include the engine displacement (e.g., 5.3L), the engine code (e.g., LM7), and the engine family (e.g., LS).



  • Locate the engine in your Chevy truck

  • Look for any identification markings on the engine block, cylinder head, or other visible components

  • Use the engine code or other information to research the engine specifications


If you're unsure about the engine identification markings, you can consult a Chevy service manual or contact a local Chevy dealer for assistance.


Check the Owner's Manual


Finally, you can also find information about your Chevy truck's engine in the owner's manual. The owner's manual will typically list the engine specifications, including the displacement, horsepower, and other details.



  • Locate the owner's manual for your Chevy truck

  • Look for the section that lists the engine specifications

  • Use this information to determine the engine in your vehicle


By following these steps, you should be able to easily determine the engine in your Chevy truck and access the necessary information to maintain, repair, or modify your vehicle as needed.

Can I look up my engine by VIN number?


To get a Vehicle History Report, access the “VIN Lookup & Decoder” by entering the VIN and clicking the “Check VIN” button. The next page will display the vehicle's information, including the year, make, model, engine, color, packages, and more when available, along with an option to pull its vehicle history.

The best way to determine which engine you have is from the Vehicle Identification Number (VIN) on the original vehicle. Locate the 8th digit of the VIN. Consult the tables below to identify your engine.



What digit of the VIN tells you engine?


The eighth digit of the VIN (Vehicle Identification Number) typically tells you the engine type for most modern vehicles. This digit acts as a code, and its meaning varies by manufacturer and model year. You will need to consult a specific decoding chart for the correct brand and year to find the engine details associated with that eighth digit.

  • Manufacturer-specific codes: Automakers use their own systems, so an "F" could mean one thing for a 2017 Ford and something else for a 2011 Ford. 
  • Decoding is key: Since the code is just a key, you can't know the engine type just by looking at the digit alone. You need to match it with the correct manufacturer and model year reference guide. 
  • Vehicle Descriptor Section: Digits 4 through 8 of the VIN are collectively known as the Vehicle Descriptor Section and contain information like engine type, body style, and model.
