Source note on shared footage
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
The video above shows you the steps needed to check the power steering fluid level in your 1999 Ford Expedition. Checking the power steering fluid level in your Expedition is relatively easy and should be done once a month or if you are experienced difficulty turning the wheel or steering your Expedition. Your Expedition should be parked on a level surface and your 5.4 liter engine should be cold to the touch.If the power steering fluid level in your Expedition is low, fill it up to the maximum line with power steering fluid and check it again in a week to determine if you have a leak. The power steering fluid reservoir will typically have a symbol of a steering wheel on the cap. Likewise, if your Expedition has electric power steering, you may see a steering wheel picture with an explanation point next to it on your dashboard to indicate power steering problems.

上述视频展示了如何检查您的 1999 福特 Expedition 车辆的转向助力油液位。 检查Expedition的转向助力油液位相对简单，建议每月检查一次，或在您发现方向盘转向困难或驾驶Expedition时转向不顺畅的情况下进行检查。 将 Expedition 停放在水平地面上，确保 5.4 升发动机已冷却，触摸时不热。如果 Expedition 的转向助力油液位偏低，请加注转向助力油至最高刻度线，并在一周后再次检查，以确定是否存在渗漏。 转向助力油储液罐的盖子上通常会有一个方向盘的标志。 同样，如果您的 Expedition 配备了电动助力转向系统，您可能会在仪表盘上看到一个方向盘的图片，并附有说明标记，以指示转向助力系统出现故障。
