The easiest way to find your car's engine size is to check the vehicle identification number (VIN), which is the most reliable method. You can decode the VIN online for free or look for a badge on the engine bay or vehicle exterior. Engine size, or displacement, is typically measured in liters (L) or cubic centimeters (cc) and represents the total volume of air and fuel the engine's cylinders can combust.
Start by locating your 17-character VIN, usually found on the dashboard near the windshield's lower corner or on the driver's side door jamb. The 8th character often specifically indicates the engine code. Use a free online VIN decoder website, enter the full VIN, and the results will list your engine's specifications, including its size in liters.
If you're near the car, look for badging on the rear or sides of the vehicle. Models like "Camry SE 3.5L" or "F-150 5.0L" have the engine size directly in the name. Under the hood, a sticker on the engine itself or on the underside of the hood may also list the displacement. Your owner's manual is another definitive source, with engine details usually in the specifications section at the back.
For quick reference, here are common engine sizes for popular vehicle types:
| Vehicle Type | Common Engine Sizes (Liters) |
|---|---|
| Compact Sedan (e.g., Honda Civic) | 1.5L, 2.0L |
| Midsize Sedan (e.g., Toyota Camry) | 2.5L, 3.5L |
| Full-size Truck (e.g., Ford F-150) | 2.7L, 3.5L, 5.0L |
| Performance Car (e.g., Chevrolet Camaro) | 2.0L, 3.6L, 6.2L |
| Subcompact SUV (e.g., Hyundai Kona) | 2.0L, 1.6L Turbo |
Knowing your engine size is crucial for tasks like ordering the correct parts, determining insurance costs, and understanding your vehicle's performance potential and fuel efficiency.

Pop the hood and look for a sticker. There's almost always one right on the top of the engine or on the underside of the hood that'll say the liters right there. If not, check the back of the car. A lot of models have it as part of the name, like "Escape 2.5L." It's the fastest way if you're standing next to your car. No tools needed.

As a buyer, the engine size is a key factor. I always check the VIN on the car's paperwork or dashboard. I then use my phone to run a quick VIN decoder search. It gives you the exact engine specs and confirms the seller isn't just guessing. It’s more reliable than trusting a badge on the car, which could have been swapped. This one step can save you from a lot of potential issues down the road.
