Finding Your Engine Size On Engine Block

There will be a wide range in engine sizes due to vehicle type and manufacturer. Engines are available in a range of sizes to cater to different customer requirements.

However, this difference is not a problem when trying to determine the engine size from the engine block. The engine number can be located by looking at the VIN or the alphabetical characters on the block casting.

The engine decal or VIN has a specific number that automakers use to determine the engine capacity. Here, we’ll show you how to read the engine block and determine the engine size. Plus, you’ll find out how to identify my engine model even without the VIN.

How to use the engine block to find the engine size

Starting at the assembly line, every vehicle is assigned an engine number by the manufacturer. You can access specific information about the car by deciphering the coded data contained in the engine number. Take vehicle engine numbers as an example; they reveal the manufacturer’s nation, year of production, engine type, and engine size.

Step 1

Raise the hood of the engine and open it. Find the metal plate that encircles the water pump and alternator. Jot down the figure; we’ll return to it later. From one engine to another, you can find the metal plate in a different spot. Some cars have the serial numbers stamped onto the engine block.

Step 2

Raise the front end of the car and use a jack stand to steady it. Always use jack stands before sliding under a jacked vehicle. No matter how strong the jack is, it can’t support a vehicle’s weight. Serious harm may result if the car slides off the jack.

Step 3

Under the car, slide a laying board. Find a spot where you can be near the gearbox and engine. Find the engine’s casting number. Mark the paper with the number. Depending on your car type, the number could be six digits or longer. Also, the engine block’s side can indicate the location of the number.

Step 4

Now, cross-reference the numbers using Google. To find the engine block number lookup for your Toyota, for example, type “Toyota engine block number lookup” into your search box. To verify the casting number on your General Motors vehicle, go to the Kendrick-auto website. The engine size may be found at that point.

How to find the engine size using VIN

A vehicle’s VIN can tell you its engine size. If you would rather not put yourself in danger by crawling underneath the car, this is one method you can use.

  • Step 1: One must first open the driver’s door in order to see the vehicle identification number (VIN) stamped on it. Also, usually by the driver’s side, around the bottom of the windshield, you may see the vehicle identification number (VIN). This post, “Top VIN Checks,” is another option to consider.
  • Step 2: The second step is to locate the 17-digit VIN. Make a note of the figures.
  • Step 3: Write down the eight-digit code. The vehicle’s engine type is determined by the eighth digit of the number.
