How to Add Power Steering Fluid to a 1998 Pontiac Bonneville


The power-steering unit on the 1998 Pontiac Bonneville is a hydraulic unit that assists turning the front tires while driving. Power-steering fluid is needed to help run the unit. Though power-steering fluid is not consumed like gasoline, a leak may reduce the amount of fluid in your car. If you hear a loud squeak when turning the wheel, check the power-steering fluid level and add additional fluid if needed.

Things You'll Need

  • Rag
  • Power-steering fluid
  • Park the 1998 Pontiac Bonneville on a flat surface, engage the parking brake and open the hood to allow the engine to cool. You should add power-steering fluid when the engine is cool.

  • Locate the fluid reservoir in the engine compartment. The reservoir is located near the back of the passenger side of the engine compartment, to the right of the radiator coolant reservoir.

  • Open the cap of the power-steering reservoir and wipe off the dipstick with a rag.

  • Reattach the cap, remove it from the reservoir and check the fluid level on the dipstick. You need to add fluid if the fluid level is below the “Full Cold” mark on the dipstick.

  • Pour power-steering fluid into the reservoir in small amounts and continually check the fluid level on the dipstick using the method described in Step 4.

  • Secure the fluid reservoir cap to the reservoir when the fluid level reaches the “Full Cold” mark.
