The easiest way to find your car's engine size is to check the Vehicle Identification Number (VIN), which is a unique code for your car. You can find the VIN on the driver's side dashboard, visible through the windshield, or on the sticker inside the driver's side door jamb. The 8th character of the VIN often corresponds to the engine code. You can then use a free online VIN decoder to get the exact engine displacement, which is measured in liters (L) or cubic centimeters (cc). For example, a "2.0L" engine has a displacement of 2.0 liters.
Other reliable methods include checking your vehicle's registration document or insurance papers, where the engine size is always listed. Your owner's manual is another excellent resource, usually containing a specifications section with this information. If you're near the car, look under the hood for a sticker or engraved information on the engine itself that states the displacement. Sometimes, it's also listed on the emissions sticker in the engine bay.
For quick reference, here are common locations and their reliability:
| Method | Where to Find It | Reliability & Notes |
|---|---|---|
| VIN Decoder | 17-character VIN on dashboard/door jamb | High; provides official data from manufacturer |
| Vehicle Registration | Document from your state's DMV | Very High; legal document |
| Owner's Manual | Glove compartment or digital version | Very High; direct from manufacturer |
| Engine Bay Sticker | Under the hood, on the engine or strut tower | High; specific to your exact engine |
| Insurance Documents | Policy documents or insurance card | High; used for policy calculation |
| Door Jamb Sticker | Inside the driver's side door | Medium; may show GVWR, not always engine size |
If these methods don't work, you can always call a dealership's service department with your VIN; they can look it up in their system for you.

Grab your car registration or insurance card—it's right there on the paperwork. That's the most official way and you know it's correct. No need to pop the hood or search online. If you don't have those handy, just type your VIN into a free decoder website. The VIN is that long number on the dashboard by the windshield. It'll tell you everything about your car's engine in seconds.
