    Clean all disassembled parts in the designated liquid or solvent prior to inspection or assembly.
  3. 8
    Replace oil seals, gaskets, packings, O-rings, locking washers, cotter pins, self-locking nuts, etc. with new ones.
  4. 9
    Replace inner and outer races of tapered roller bearings and needle bearings as a set.
  5. 10
    Arrange the disassembled parts in accordance with their assembled locations and sequence.
  6. 11
    Do not touch the terminals of electrical components which use microcomputers (such as electronic control units). Static electricity may damage internal electronic components.
  7. 12
    After disconnecting vacuum or air hoses, attach a tag to indicate the proper connection.
  8. 13
    Use only the lubricants specified in MA section.
  9. 14

    When repairing the fuel, oil, water, vacuum or exhaust systems, check all affected lines for leaks.
  12. 17
    Dispose of drained oil or the solvent used for cleaning parts in an appropriate manner.

Precautions for E.F.I. or E.C.C.S. Engine

  1. 1
    Before connecting or disconnecting E.F.I. or E.C.C.S. harness connector to or from any E.F.I. or E.C.C.S. control unit, be sure to turn the ignition switch to the "OFF" position and disconnect the negative battery terminal. Otherwise, there may be damage to control unit.

  2. 2
    Before disconnecting pressurized fuel line from fuel pump to injectors, be sure to release fuel pressure to eliminate danger.
  3. 3
    Be careful not to jar components such as control unit and air flow meter.

Precautions for Catalyst

If a large amount of unburned fuel flows into the converter, the converter temperature will be excessively high. To prevent this, follow the procedure below:

Precautions for Catalyst

  1. 1
    Use unleaded gasoline only. Leaded gasoline will seriously damage the catalytic converter.
  2. 2
    When checking for ignition spark or measuring engine compression, make tests quickly and only when necessary.
  3. 3
    Do not run engine when the fuel tank level is low, otherwise the engine may misfire causing damage to the converter.
  4. 4
    Do not place the vehicle on inflammable material. Keep inflammable material off the exhaust pipe.
