LEVEL CHECK & FLUID RECOMMENDATIONS
Power steering fluid level should be checked at least every 7,500 miles. The power steering pump is belt driven and has the dipstick built into the filler cap. To prevent possible over-filling, check the fluid level only when the fluid has warmed up to operating temperature and with the front wheels turned straight ahead. If the level is low, fill the pump reservoir with DEXRON® Automatic Transmission Fluid on 1974-76 cars. 1977 and later models require GM power steering fluid (or its equivalent), available at any Buick, Olds, Pontiac or Chevrolet dealer. Fill the reservoir until the fluid level measures "full" on the reservoir dipstick. When the fluid level is low, there is usually a moaning sound coming from the pump as the front wheels are turned, especially when standing still or parking. The steering wheel will also be difficult to turn when fluid level in the pump reservoir gets low.
