  5. Install the generator. Install the A/C compressor bracket. Position the PS gear and cooler to the front suspension crossmember. See Figure and Figure . Install the BPMV bracket.
  6. Install the PS gear mounting bolts and nuts. Tighten the power steering gear mounting nuts to specification. See TORQUE SPECIFICATIONS  . Install the PS cooler retaining bolts. Tighten the power steering cooler retaining bolts to specification.
  7. Connect the intermediate shaft lower coupling to the PS gear; be sure that the intermediate shaft and the PS gear steering shaft are orientated as marked prior to disconnecting them. Slide the intermediate shaft lower coupling onto the PS gear steering shaft. Install the intermediate shaft lower coupling bolt. See Figure . Tighten the steering gear intermediate shaft lower coupling bolt to specification.
  8. Install the intermediate shaft lower coupling shield. Lower the vehicle. Remove the tie-off retainer and carefully pivot the AC condenser and the radiator back into position. Install the radiator outlet hose to the radiator outlet. Position the radiator outlet hose clamp onto the radiator outlet.
  9. Install the radiator inlet hose to the radiator inlet. Position the radiator inlet hose clamp onto the radiator inlet. Install the surge tank upper hose to the radiator inlet. Position the coolant surge tank upper hose clamp onto the radiator inlet.
  10. Install the compressor hose to the condenser. See Figure . Using a back-up wrench on the condenser fitting (2), tighten the compressor hose fitting (1) to the condenser. See Figure . Tighten the fitting to specification. See TORQUE SPECIFICATIONS  . Connect the front evaporator tube to the condenser. Install the front evaporator tube-to-condenser bolt. See Figure . Tighten the fitting to specification.
  11. Install the upper and lower radiator support. Install the air cleaner assembly. Connect the upper TOC line to the oil cooler using the following steps: Push the TOC pipe into the quick connect fitting, until a click is heard. Tug gently in the TOC line to ensure a proper connection. Position the plastic retainer over the connection.
  12. Raise the vehicle. Connect the lower TOC line to the oil cooler using the following steps: Push the TOC pipe into the quick connect fitting, until a click is heard. Tug gently in the TOC line to ensure a proper connection. Position the plastic retainer over the connection.
