Procedure notes
The video above shows you the steps needed to check the power steering fluid level in your 1999 Ford F-150. Checking the power steering fluid level in your F-150 is relatively easy and should be done once a month or if you are experienced difficulty turning the wheel or steering your F-150. Your F-150 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 F-150 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 F-150 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 F-150 车辆的转向助力油液位。 检查F-150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F-150时转向不顺畅的情况下进行检查。 您的 F-150 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F-150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 F-150 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。
