  1. Disconnect the negative battery cable. Drain the engine oil.
  2.  
  3. Raise and safely support the vehicle. Remove the lower splash pan, if equipped.
  4.  
  5. Remove the exhaust pipe from the manifold and from the catalyst.
  6.  
  7. Loosen the oil pan bolts in a crisscrosss pattern beginning with the outside bolt. To remove the oil pan, lightly tap the corners of the oil pan with a mallet. Clean off all the old gasket material.
  8.  
  9. Installation is the reverse of removal. On 1989 models, apply gasket sealer to the corners of the pan where it bends around the oil pump. Torque the bolts to 9 ft. lbs. (12 Nm), starting in the center and working out.

Vigor and 1991-93 Legend

See Figures 3 through 7

Oil pan removal in these vehicles requires disconnecting the lower ball joints and removing the differential. Special tools are required to remove and install the extension shaft: 07LAC-PW50100 puller, or equivalent, and 07MAF-PY40100 installer, or equivalent.

  1. Disconnect the negative battery cable. Drain the engine oil.
  2.  
  3. Raise and safely support the vehicle and remove the front wheels.
  4.

  6.  
  7. Remove the lower ball joint nut and use a ball joint press tool to disconnect the ball joint from the control arm.
  8.  
  9. Carefully pry the inner CV-joints out of their sockets. Wrap them in plastic to keep them clean and do not let the drive shafts hang by the outer CV-joint.
  10.  
  11. Remove the engine splash shield and lower plate from the rear beam.
  12.  

On Legend, some of the bolts have a special coating for use in aluminum alloy. Do not substitute normal steel fasteners.

  1. Drain the engine oil and coolant. On Vigor, remove the transmission mount and bracket.
  2.  
  3. Drain the oil from the differential.
  4.  
  5. Without disconnecting the hoses, remove the power steering speed sensor from the differential.
  6.  
  7. Disconnect the differential oil cooler hoses.
