27 Correctly reinstall or replace fuel tank cap.
HINT:

When reinstalling the fuel tank cap, tighten it until a few click sounds are heard.

When replacing the fuel tank cap, use a fuel tank cap that meets OEM specifications, and install it until
a few click sounds are heard.
NEXT Go to step 37.
28 Replace fuel tank cap.
HINT:
When installing the fuel tank cap, tighten it until a few click sounds are heard.
NEXT Go to step 37.
29 Repair EVAP leak part.
(a) Prepare a rubber hose with a 15 to 18.5 mm inside diame-
ter.
(b) Reinstall the fuel tank cap.
(c) Disconnect the atmospheric side hose of the pump mod-
ule.
(d) Connect the rubber tube to the pump module.
(e) Using SST, pinch the rubber tube to close the canister
passage to air.
SST 00002±6872A
(f) Connect a pressure gauge (SST) to the service port
(green cap near the air cleaner box).
(g) Pressurize the EVAP system to 3.2 to 3.7 kPa (24 to 28
mmHg).
(h) Apply soapy water to the piping and connecting parts of
the EVAP system. Look for areas where bubbles appear.
This indicates leaking points.
(i) Repair or replace leaking point.
HINT:

If the system has leaks, a whistling sound will be heard.

Disconnect the hose between the canister and the fuel
tank from the canister. Close the canister hose connected
to the fuel tank, and conduct an inspection. In this way, the
fuel tank can be excluded as an area suspected of caus-
ing fuel leaks.
NEXT Go to step 36.

Noise occurs
INSPECTION PROCEDURE
1 Check of speaker installation.
CHECK:
Check if each speaker is securely installed.
OK:
Each speaker is securely installed.
HINT:
The radio is equipped with a noise prevention system that blocks excessively loud noise. If such noise oc-
curs, check the all wiring is proper and that the antenna installation part ground and noise±prevention equip-
ment are installed.
Condition in which noise occursNoise type
Noise increases when the accelerator pedal is depressed, but stops when
the engine is stopped.Generator noise
Noise occurs during A/C or the heater operation.Blower motor noise
Noise occurs when the vehicle accelerates rapidly on an unpaved road or
after the ignition switch is turned on.Fuel pump noise
Noise occurs when the horn switch is pressed and released or when pressed
and held.Horn noise
Quiet noise occurs while the engine is running, but stops when the engine is
stopped.Ignition noise
Noise occurs synchronously with the blink of the turn signal.Flasher noise
Noise occurs during window washer operation.Washer noise
Noise occurs while the engine is running, and it continues even after the en-
gine is stopped.Water temperature sensor noise
Noise occurs during wiper operation.Wiper noise
Noise occurs when the brake pedal is depressed.Stop light switch noise
Others.Static electricity stored on the vehicle
HINT:

Identify the condition under which the noise occurs, and check the noise filter on the related part.

First ensure that the noise is not coming from the outside. Failure to do so makes noise source detec-
tion difficult and may lead to a misdiagnosis.

Noise should be removed in descending order of loudness.
NG Install it properly.
OK

INSPECTION
1. INSPECT TIMING BELT
NOTICE:

Do not bend, twist or turn the timing belt inside out.

Do not allow the timing belt to come into contact with
oil, water or steam.

Do not utilize timing belt tension when installing or re-
moving the mount bolt of the camshaft timing pulley.
If there is any defect, as shown in the illustration, check these
points:
(a) Premature parting

Check for proper installation.

Check the timing cover gasket for damage and
proper installation.
(b) If the belt teeth are cracked or damaged, check to see if
either camshaft is locked.
(c) If there is noticeable wear or cracks on the belt face,
check to see if there are nicks on the side of the idler
pulley lock and water pump.
(d) If there is wear or damage on even one side of the belt,
check the belt guide and the alignment of each pulley.
(e) If there is noticeable wear on the belt teeth, check timing
cover for damage and for foreign material on the pulley
teeth.
If necessary, replace the timing belt.
2. INSPECT IDLER PULLEYS
(a) Visually check the seal portion of the idler pulley for oil
leakage.
If leakage is found, replace the idler pulley.
(b) Check that the idler pulley turns smoothly.
If necessary, replace the idler pulley.
3. INSPECT TIMING BELT TENSIONER
(a) Visually check the seal portion of the tensioner for oil leak-
age.
HINT:
If there is only the faintest trace of oil on the seal on the push
rod side, the tensioner is all right.
If leakage is found, replace the tensioner.

(b) Hold the tensioner with both hands and push the push rod
strongly as shown to check that it doesn't move.
If the push rod moves, replace the tensioner.
NOTICE:
Never hold the tensioner push rod facing downward.
(c) Measure the protrusion of the push rod from the housing
end.
Protrusion: 10.5 to 11.5 mm (0.413 to 0.453 in.)
If the protrusion is not as specified, replace the tensioner.

3. TEMPORARILY INSTALL TIMING BELT
NOTICE:
The engine should be cold.
(a) Remove any oil or water on the crankshaft pulley, oil
pump pulley, water pump pulley, No.1 idler pulley and
No.2 idler pulley, and keep them clean.
NOTICE:
Only wipe the pulleys; do not use any cleansing agent.
