Procedure notes
The video above shows you the steps needed to check the power steering fluid level in your 2007 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 2007 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。 您的 Expedition 应停放在水平地面上，且 5.4 升发动机应摸起来冰冷。
如果您的Expedition转向助力油液位偏低，请用转向助力油加注至最高刻度线，并在一周后再次检查，以确定是否存在泄漏。 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。
