Oil and filter inspection

  1. Check oil quality Check the oil for deterioration, entry of water, discoloring or thinning.
    If oil quality is visibly poor, replace the oil.
    Oil grade (2JZ-GE):
    API grade SH Energy-Conserving II or SJ, Energy-Conserving or ILSAC multigrade engine oil.
    SAE 5W-30 is the best choice for your vehicle, for good fuel economy, and good starting in cold weather.
    Oil grade (2JZ-GTE):
    API grade SH Energy-Conserving II or SJ, Energy-Conserving or ILSAC multigrade engine oil.
    Recommended viscosity is as shown in the illustration.
  2. Check engine oil level The oil level should be between the low level and full level marks on the dipstick.
    If low, check for the leakage and add oil up to full level mark.
  3. Remove engine under cover
  4. 2JZ-GTE:
    Remove No.2 air tube
    Loosen the 2 hose clamps, and remove 2 bolts and air tube.
  5. 2JZ-GTE M/T:
    Remove drive belt tension damper Remove the 2 nuts and tensioner damper.
  6. Remove drive belt Loosen the drive belt tension by turning the drive belt tensioner clockwise, and remove the drive belt.
  7. Disconnect A/C compressor from engine
    1. Remove the 4 bolts and nut.
    2. Using a torx socket (E10), remove the stud bolt.
    3. Disconnect the compressor connector.
    4. Remove 4 bolts and pull the compressor downward.
  8. Remove oil pressure switch, and install oil pressure gauge
    1. Disconnect the oil pressure switch connector.
    2. Using SST, remove the oil pressure switch.
      SST 09816-30010
    3. Install an oil pressure gauge.
  9. Reinstall A/C compressor
    1. Temporarily install the A/C compressor with the 4 bolts.
    2. Connect the compressor connector.
    3. Install the compressor with the stud bolts, 4 bolts and nut.
      Torque:
      Stud bolt: 26 N·m (265 kgf·cm, 19 ft·lbf)
      Bolt and nut: 52 N·m (530 kgf·cm, 38 ft·lbf)
  10. Reinstall drive belt
    Install the drive belt by turning the drive belt tensioner clockwise.
  11. Warm up engine
    Allow the engine to warm up to normal operating temperature.
  12. Check oil pressure Oil pressure:
    At idle
    49 kPa (0.5 kgf/cm 2 , 7.1 psi) or more
    At 3,000 rpm (2JZ-GE) or 4,000 rpm (2JZ-GTE)
    324 - 579 kPa
    (3.3 - 5.9 kgf/cm 2 , 47 - 84 psi)
  13. Remove drive belt
  14. Disconnect A/C compressor from engine
  15. Remove oil pressure gauge, and reinstall oil pressure switch
    1. Remove the oil pressure gauge.
    2. Tighten the union nut.
      Torque: 60 N·m (600 kgf·cm, 44 ft·lbf)
    3. Apply adhesive to 2 or 3 thread of the oil pressure switch.
      Adhesive:
      Part No. 08833-00080, THREE BOND 1344, LOCKTITE 242 or equivalent
    4. Using SST, install the oil pressure switch.
      SST 09816-30010
      Torque: 14 N·m (150 kgf·cm, 11 ft·lbf)
    5. Connect the oil pressure switch connector.
  16. Reinstall A/C compressor
  17. Reinstall drive belt
  18. Start engine and check for reaks
  19. 2JZ-GTE M/T:
    Install drive belt tensioner damper
    Torque: 20 N·m (200 kgf·cm, 14 ft·lbf)
  20. 2JZ-GTE:
    Reinstall No.2 air tube
  21. Reinstall engine under cover
