CHEVROLET & GMC

NOTE: If power steering fluid has foamed due to low fluid level, it will be necessary to park vehicle for approximately one hour (reservoir cap loose) so that foam can dissipate.
  1. Fill reservoir with suitable power steering fluid. Start engine and run momentarily. Add fluid if necessary. Repeat until fluid level remains constant after running engine. Raise vehicle so front end is off ground. Turn steering right and left, lightly contacting wheel stops. Add fluid if necessary. Lower vehicle.
  2. Start engine and depress brake pedal several times while turning steering wheel from stop to stop. Turn engine off and depress brake pedal several times to deplete accumulator pressure. Add fluid if necessary.
  3. If fluid is foamy, or has air in it, let vehicle stand several minutes, then repeat steps  1 and  2. The presence of air in system will cause fluid level to rise with engine off. Continue to bleed system until all air is expelled.
