Where is the battery located in a GMC G2500?

The video above shows you how to replace the battery in your 1990 GMC G2500. We recommend changing the battery in GMCs every 4 years. Although some batteries last much longer, most batteries begin breaking down chemically after four years, so you could experience dimmer headlights and other negative effects before you have a dead battery in your G2500 that you need to replace.

The battery location in a GMC G2500 can typically be found in the engine bay, but may be in the trunk, fender or inside of the vehicle. You may need to remove the air filter housing, a plastic engine cover or parts of the cowl to find the battery in your G2500. See exactly where the battery is located in your 1990 GMC G2500.

Replacing the battery in your G2500 involves removing the terminals. When you reconnect the terminals, your radio presets are likely to be cleared out. In some G2500s, you may need to re-enter a security code to get your radio to work again. Check for this code in your owners manual - it will usually be either a sticker or small card in the booklet. If you can't find it, call GMC and they will give you the code for free. In many GMCs, the transmission "learns" how you drive over time and makes adjustments, so you may experience altered driving dynamics as your car re-learns your driving style after changing the battery.
