Power steering fluid level should be checked at least once every 6,000 miles (7,500 miles for 1975-78 cars). To prevent possible overfilling, check the fluid level only when the fluid has warmed to operating temperatures and the wheels are turned straight ahead. If the level is low, fill the pump reservoir with DEXRON® Automatic Transmission Fluid on 1976 and earlier cars. 1977-78 cars require GM power steering fluid, until the fluid level measures full on the reservoir dipstick. Low fluid level usually produces a moaning sound as the wheels are turned (especially when standing still or parking) and increases steering wheel effort.
