To be absolutely certain, you should:
* Check your owner's manual: This is the most reliable source of information.
* Look at the battery currently installed (if one is): The group size is usually printed on a label on top of the battery.
* Check the sticker on the battery tray: Sometimes the recommended group size is listed on a sticker in the battery tray.
* Consult a parts store: Provide them with the year, make, model, and engine of your Vandura. They can look up the correct battery size in their system.
Don't rely solely on online information; always double-check with your vehicle's documentation or a parts professional. The engine size and options can influence the battery size needed.
