NOTE:  Use fender covers to avoid damaging painted surfaces.
 To avoid damaging the wire and terminals, unplug the wiring connectors carefully while holding the
connector portion.
 Mark all wiring and hoses to avoid misconnection. Also, be sure that they do not contact other wiring or
hoses, or interfere with other parts.
1. Secure the hood in the wide open position (support rod in the lower hole).
2. Relieve the fuel pressure (see page 11-322).
3. Do the battery removal procedure (see page 22-69).
4. Disconnect the vacuum hose and the breather pipe, then remove the intake air duct (see step 2 on page
9-3).
5. Remove the air cleaner assembly (see page 11-345).
6. Remove the under-cowl panel (see step 4 on page 20-164). 7. Disconnect the connector (A), and remove the
harness clamps (B), then remove the pipe (C).
8. Disconnect the battery cables (A) from the under- hood fuse/relay box.
9. Remove the harness clamp (B). (cont’d)

57. Connect the battery cables (A) to the under-hood fuse/relay box.
58. Install the harness clamp (B). 59. Install the pipe (A).
60. Connect the connector (B), and install the harness
clamps (C).

62. Install the air cleaner assembly (see page 11-345).
63. Install the front wheels.
64. Do the battery installation procedure (see page 22-69).
65. Inspect for fuel leaks. Turn the ignition switch to ON (II) (do not operate the starter) so the fuel pump
runs for about 2 seconds and pressurizes the fuel
line. Repeat this operation three times, then check
for fuel leakage at any point in the fuel line.
66. Refill the engine with engine oil (see step 4 on page 8-10).

1. Disconnect the 2P connectors from the radiator fan motor and the A/C condenser fan motor.
2. Test the motor by connecting battery power to terminal No. 2 and ground to terminal No. 1.
3. If the motor fails to run or does not run smoothly, replace it (see page 10-19). Replace the thermostat if it is stuck in the open position
at room temperature.
To test a closed thermostat:
1. Suspend the thermostat (A) in a container of water. Do not let the thermostat and the thermometer (B)
touch the bottom of the hot container.
2. Heat the water, and check the temperature with a thermometer. Check the temperature when the
thermostat first opens, then check the temperature
again when the thermostat is fully open.
3. Measure the lift height of the thermostat when it is fully open. If it thermostat is not within the
specification, replace it.
