  6.  
  7. Remove the engine and transaxle splash shields.
    CAUTION
    The EPA warns that prolonged contact with used engine oil may cause a number of skin disorders, including cancer! You should make every effort to minimize your exposure to used engine oil. Protective gloves should be worn when changing the oil. Wash your hands and any other exposed skin areas as soon as possible after exposure to used engine oil. Soap and water, or waterless hand cleaner should be used.

  8.  
  9. Drain the engine oil. When all the oil has been drained, install the drain plug and tighten it to 22-29 ft. lbs. (29-39 Nm).
  10.  
  11. On 1999-00 vehicles, unclip the heated oxygen sensor wiring harness from the transverse member.
  12.  
  13. Place an underbody type screw-jack or equivalent under the crankshaft pulley. Cover the end of the jack with rags to prevent damage to the crankshaft pulley. Take up just enough of the engine's weight to allow the engine mounts to be disconnected.
  14.  
  15. Remove the front (left) and rear (right) engine mount through bolts.
  16.  
  17. Remove the two rear A/C refrigerant/heater pipe hold down bracket bolts.
  18.  
  19. Remove the four transverse member bolts and remove the transverse member.
  20.  
  21. On 1999-00 vehicles, disconnect the heated oxygen sensor electrical connector.
  22.  
  23. Remove the exhaust inlet pipe.
  24.  
  25. Remove the front (left) and rear (right) transaxle-to-engine braces. Remove the engine-to-transaxle separator plate.
  26.  
  27. On 1999-00 vehicles, remove the two bolts from the exhaust pipe bracket and remove the bracket.
  28.  
  29. Remove the eighteen oil pan bolts, in the reverse order of the tightening sequence.
  30.  
  31. Remove the oil pan. It may be necessary to tap the pan with a rubber mallet to break the seal between the pan and the engine. The pan or block mating surfaces may be damaged if a screwdriver is driven in between them to break the seal.
  32.  

To install:

  1. The installation is the reverse of removal, but please note the following important steps.
  2.  
  3. Be sure that all old sealing material is removed from the oil pan and engine mating surfaces. A gasket scraper and solvent may be used, however, be careful not to nick or gouge either surface.
  4.  
  5. When installing the new oil pan end seals, apply Loctite® Ultra Gray 599 Silicone Sealer or its equivalent to the ends of the seals.
  6.  
  7. Apply a 0.138-0.177 inch (3.5-4.5mm) wide bead of Loctite® Ultra Gray 599 Silicone Sealer or its equivalent in the groove of the oil pan rails, staying to the inside edge around the bolt holes.
  8.  
  9. Install the oil pan on the engine block. Tighten the oil pan bolts, in sequence, to 62-70 inch lbs. (7-8 Nm).
  10.  
  11. When installing the transaxle-to-engine braces, tighten the bolts to 22-30 ft. lbs. (30-40 Nm).
  12.  
  13. When installing the transverse member, tighten the bolts to 58-65 ft. lbs. (78-88 Nm).
  14.  
  15. When installing the engine mount through bolts, tighten them to 58-65 ft. lbs. (78-88 Nm).
