Check & Add Power Steering Fluid to a Cadillac

Is your steering wheel difficult to turn, feels stiff when turning, or do you hear a whining noise when turning the steering wheel? ?

The power steering fluid may be low. Follow the procedures below to learn how to check the fluid level on a Cadillac and add power steering fluid.

Symptoms

Common symptoms that your power steering system fluid level is low:

• You hear a groaning noise when turning the steering wheel,
• The steering wheel is difficult to turn,
• Whining noise when turning the steering wheel,
• Cadillac steering wheel is slow to respond,
• Stiff steering wheel,
• Squealing noise at startup

Does Your Cadillac Use Power Steering Fluid?

Older Cadillacs with hydraulic steering have a fluid reservoir. Many newer models, such as the ATS, CT4, CT5 and XT series, use electric power steering with no fluid to check. If yours has electric steering and the steering feels heavy or a steering warning appears, the cause is electrical, and the steering system codes will point to it.

Power steering fluid does not get used up. If the level keeps dropping, look for leaks at the pump, hoses and rack.

What you will need

• Cadillac Power Steering Fluid

Procedure

1. Locate the hood release underneath the dash of your Cadillac. Pull the lever until you hear the hood pop open.
2. Next, you need to release the hood safety latch at the front of the hood. Lift the hood and secure it.
3. Locate the power steering pump on your Cadillac. The power steering pump is mounted on the engine. In this case, the power steering pump is located on the driver’s side of the engine bay. If you are unsure, look it up in the owner’s manual.
4. Remove the cap counterclockwise. Inspect the current condition of the power steering fluid. If you look carefully at the side of the power steering fluid or the cap dipstick, you will notice a Low and Max mark.
5. Add a power steering fluid if the power steering level is below the minimum.

How to Add Power Steering Fluid to a Cadillac

If the power steering level is below the minimum mark, add power steering fluid to bring the Min and Maximum mark levels. Do not overfill.

1. Drive your Cadillac for at least fifteen minutes to warm up the existing power steering fluid. (If the level is extremely low, add power steering fluid before the warm-up procedure.)
2. Turn off the engine and set the parking brake.
3. Park your Cadillac on level ground and open the hood. The hood release is under the dashboard, driver’s side.
4. Locate the power steering reservoir at the front of the engine.
5. Remove the cap from the power steering fluid reservoir.
6. Add power steering fluid until you bring the level between the Min and Max marks.

It is not recommended to drive your Cadillac with no power steering fluid. Not only will you hear a groaning noise and have a hard-to-turn steering wheel, but you can also burn the power steering pump. This guide applies to Cadillac ATS, CTS, XTS, CT6, XT5, Escalade, SRX, DTS, STS, BLS, and XLR.
