Description:
Check the power steering fluid level at every oil change. Refer to your car's owner's manual for specific recommendations on the type of power steering fluid to use. Fluids need to be compatible with hoses and seals and in some cases the recommended fluid may be automatic transmission fluids such as Type F or Dexron®.

Purpose:
The fluid lubricates and transmits the pressure needed for power-assisted steering.

Maintenance Tips/Suggestions:
It's possible to check the power steering fluid level when your car is cold, but it's usually recommended to check the fluid with the car warmed up. Many cars today use a semi-transparent reservoir for power steering fluid, so look for a fluid level mark on the outside. If the reservoir has no markings, open the reservoir's cap. There should be a small dipstick attached that provides the level reading.
