Special Caution Items For This Car

  1. 1
    Fuel Line Servicing: Relieve fuel pressure by loosening the service bolt provided on the top of the fuel filter before disconnecting a fuel hose or a fuel pipe.
    Close-up of the fuel filter with the service bolt on top, used to relieve fuel pressure. A shop towel is wrapped around the area to catch fuel.
  2. 2
    Fuel Line Servicing (cont'd): Be sure to replace washers, O-rings, and rubber seals with new ones when servicing fuel line parts. Always apply oil to the surfaces of O-rings and seal rings before installation. Never use brake fluid, radiator fluid, vegetable oils or alcohol-based oils. When assembling the flare joint of the high-pressure fuel line, clean the joint and coat with new engine oil.

  4. 4
    Inspection for fuel leakage: After assembling fuel line parts, turn ON the ignition switch (do not operate the starter) so that the fuel pump is operated for approximately two seconds and the fuel is pressurized. Repeat this operation two or three times and check whether any fuel leakage has occurred in any of the various points in the fuel line.
  5. 5
    Installation of an amateur radio for cars equipped with PGM-FI. Care has been taken for the PGM-FI ECU (computer) and its wiring to prevent erroneous operation from external interference, but erroneous operation of the computer may be caused by extremely strong radio waves. Attention must be paid to the following items to prevent erroneous operation of the computer.
  6. 6
    Apply liquid gasket to the transmission, oil pump cover, right side cover and water outlet. Use HONDA PART NO 08740-99986 as a liquid gasket.
