We have a massive and growing video library, but we don't have everything...yet.
Car companies often use the same engines in different cars. They also slightly alter the styling and sell the same car by two different names (amongst other tricks to help offset development costs).
Our system selects the most applicable video for your car based, in part, on these characteristics. The video displayed may not look exactly like your car, but may be relevant enough for you to get a good idea how to do it.

我们有一个庞大且不断增长的视频资料库，但还没有全部内容……
汽车制造商经常在不同车型中使用相同的发动机。 它们还略微调整了外观设计，并以两个不同的名称销售同一款车（以及其他一些技巧，以帮助抵消开发成本）。
我们的系统会根据这些特性，部分地选择最适合您车辆的视频。 视频中显示的内容可能与您的车辆外观不完全相同，但可能足够相关，让您了解如何操作。
Procedure notes
Where is the battery located in a Chevrolet Express 2500?
The video above shows you how to replace the battery in your 2003 Chevrolet Express 2500. We recommend changing the battery in Chevrolets 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 Express 2500 that you need to replace.
The battery location in a Chevrolet Express 2500 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 Express 2500. See exactly where the battery is located in your 2003 Chevrolet Express 2500.
Replacing the battery in your Express 2500 involves removing the terminals. When you reconnect the terminals, your radio presets are likely to be cleared out. In some Express 2500s, 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 Chevrolet and they will give you the code for free. In many Chevrolets, 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.

在 雪佛兰 Express 2500 中，蓄电池位于何处？
上面的视频展示了如何更换您的 2003 雪佛兰 Express 2500 车辆的电池。 我们建议每隔 4 年为 雪佛兰车型 更换一次电池。 虽然部分蓄电池寿命更长，但大多数蓄电池在使用四年后会开始出现化学性能衰退。因此，在 Express 2500 的蓄电池彻底失效、需要更换之前，你可能就会先遇到前照灯变暗等问题。
在 雪佛兰 Express 2500 车辆中，蓄电池通常位于发动机舱，但也可能位于后备箱、车门板或车内。 您可能需要拆除空气滤清器罩、塑料发动机盖或车头罩的某些部件，才能找到您的 Express 2500 车辆上的蓄电池。 请查看您的 2003 雪佛兰 Express 2500 车辆中蓄电池的具体位置。
在您的 Express 2500 上更换电池需要拆除端子。 当你重新连接端子时，收音机的预设设置可能会被清除。 在某些Express 2500s 中，您可能需要重新输入安全码才能让收音机恢复正常工作。 在您的用户手册中查找此故障码 - 它通常会以标签或书本内的小卡片形式存在。 如果找不到，请联系 雪佛兰，他们将免费为您提供该代码。 在许多 雪佛兰车型 车辆中，变速箱会随着时间推移学习你的驾驶习惯并进行相应调整，因此在更换电池后，车辆重新学习驾驶风格时，你可能会感受到驾驶动态的改变。
