  1. Connect the pressure and return hoses. Route the hoses in the same manner as they were prior to removal. They should be routed smoothly with no sharp bends. Tighten the pump end hose fitting to 30 ft. lbs. (40 Nm) on models through 1974, or 35 ft. lbs. (47 Nm) for 1975 and later. Tighten the gear end fitting to 19 ft. lbs. (25 Nm) on models through 1974, or 25 ft. lbs. (33 Nm) for 1975 and later. The hoses should remain at least 1 in. (25mm) away from the pulleys, battery case, and brake lines, and at least 2 in. (50mm) away from exhaust manifolds. If equipped, the protective sponge sleeves should be used to protect the hoses from contact with other parts.

  3. Fill the pump with the specified power steering fluid or its equivalent.
  4.  
  5. Start the engine and turn the steering wheel lock-to-lock several times to bleed the system. Check for leaks and recheck the fluid level.
