Power steering fluid low or empty

Low power steering fluid makes steering heavier and can cause whining noises, and it almost always means there's a leak somewhere that needs to be found rather than just refilled.

Symptoms

  • Power steering reservoir reads low or empty on the dipstick or sight glass
  • Steering feels heavier than normal
  • Whining noise when turning

Likely causes

  • CommonLeak somewhere in the power steering systemFluid doesn't disappear on its own; a low level almost always means it's leaking out somewhere.
  • PossibleNever topped off after a previous repairSometimes fluid is simply low following recent work and needs a top-off.

What to do

  1. Check the fluid level against the markings on the reservoir, using the correct fluid type for your vehicle.
  2. Look underneath and around the pump, hoses, and steering rack for signs of a leak.
  3. Top off the fluid to the correct level.
  4. Drive the car and recheck the level after a day or two to see if it's dropping again.
  5. If it's dropping, have a mechanic find and repair the specific leak rather than continuing to top it off.
