The video above shows you the steps needed to check the power steering fluid level in your 2021 GMC Sierra 3500 HD. Checking the power steering fluid level in your Sierra 3500 HD is relatively easy and should be done once a month or if you are experienced difficulty turning the wheel or steering your Sierra 3500 HD. Your Sierra 3500 HD should be parked on a level surface and your 6.6 liter engine should be cold to the touch.
If the power steering fluid level in your Sierra 3500 HD 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 Sierra 3500 HD 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.
