  3. Drain the cooling system by using the procedures in General Information & Maintenance .
  4.  
  5. Loosen the lug nuts of the right front wheel slightly before raising the vehicle.
  6.  
  7. Raise and support the front of the vehicle on jackstands, then drain the engine oil.
  8.  
  9. Support the engine with a second floor jack. Use a piece of wood between the floor jack and the engine to help prevent damage to the engine. Make certain not to raise the vehicle with the second floor jack to the point where the vehicle's weight is lifted from the jackstands. The second floor jack is only to take the weight off of the engine. Support the engine in a way that the oil pan can be removed later.
  10.  
  11. Remove the right engine mount.

  1. Remove the oil pan and oil pump pick-up. It may be necessary to remove the transaxle inspection cover.
  2.  
  3. Remove the right wheel and inner splash shield.
  4.  
  5. Remove the accessory drive belt. Refer to General Information & Maintenance for this procedure.
  6.  
  7. Remove the A/C compressor and set aside with the A/C lines still attached. If the lines are removed without having the A/C system discharged first, severe personal injury, as well as environmental damage, can occur.
  8.  
  9. Remove the A/C compressor bracket from the engine.
  10.  
  11. Refer to the crankshaft pulley procedures and remove the pulley from the crankshaft.
  12.

  17. Loosen and remove the securing bolt for the camshaft position sensor on the upper edge of the Chain Case Cover (CCC). Gently pull the camshaft position sensor out of the CCC and set aside. Do not pull on the sensor lead. There is an O-ring on the sensor case. The O-ring may make removal difficult. A light tap to the top of the sensor prior to removal may reduce the force needed for removal.
  18.  
  19. Remove the seven CCC fasteners. Remove the CCC being careful not to damage the sealing surface of the engine block or the CCC.
  20.  
  21. Clean all of the mounting surfaces of the engine block and CCC of all dirt, oil or old gasket material. Remove all of the old O-rings from the CCC, these are located in the two coolant passages and the oil pump-to-engine outlet hole. New O-rings will be needed.

    1. If installing the original sensor, clean the old spacer off of the sensor face. A new spacer must be attached to the face before installation.
    2.  
    3. Inspect the O-ring for damage and replace with a new one if needed.
    4.  
    5. If the sensor is being replaced with a new one, confirm that the paper spacer is attached to the face of the sensor and the O-ring is positioned in the groove of the new sensor.
    6.  
    7. Apply a couple of drops of clean engine oil to the O-ring prior to installation. Install the sensor into the chain case cover and push the sensor down until contact is made with the camshaft timing gear. While holding the sensor in this position, install and tighten the retaining bolt to 10 ft. lbs. (14 Nm).
