(o) Disconnect the pressure gauge from the EVAP service
port on the purge line.
5. CHECK AIR TIGHTNESS IN FUEL TANK AND FILLER
PIPE
(a) Check the operation.
(1) Remove the fuel tank (see page 11-28).
(2) Remove the fuel tank vent hose from the fuel tank
(see page 11-28).
(3) Connect the pressure gauge to the fuel tank vent
hose port of the fuel tank.
(4) Apply pressure to the fuel tank, so that the internal
pressure of the fuel tank is 4 kPa (41 gf/cm
2, 0.58
psi).
(5) Check that the internal fuel tank pressure is main-
tained for 1 minute.
(6) Check the connected portions of each hose and
pipe.
(7) Check the installed parts on the fuel tank.
If there is no abnormality, replace the fuel tank and fuel tank filler
pipe.
(8) Reinstall the fuel tank vent hose to the fuel tank (see
page 11-28).

6. INSPECT FUEL CUT OFF VALVE AND FILL CHECK
VA LV E
(a) Check the operation.
(1) Remove the fuel tank (see page 11-28).
(2) Remove the fuel tank vent hose from the fuel tank
(see page 11-28).
(3) Connect the pressure gauge to the fuel tank vent
hose port of the fuel tank.
(4) Fully fill the fuel tank with fuel.
HINT:
In the condition that the fuel is full, there is no ventilation as the
float valve of the fill check valve is closed.
(5) Install the fuel suction w/ pump & gauge tube (see
page 11-20).
(6) Securely cover the fuel pump tube, fuel tube No. 1
port and fuel tank to filler pipe port with vinyl or plas-
tic bags to perform the accurate pressure test.
(7) Apply 4 kPa (41 gf/cm
2, 0.58 psi) of pressure to the
fuel tank vent hose port of the fuel tank.

an O-ring which seals the pipe and quick connector
that can be contaminated.
Do not use any tools in this operation.
Do not bend or twist the nylon tube. Protect the quick
connector by covering it with a vinyl or plastic bag.
When the pipe and quick connector are stuck, push
and pull the quick connector to release. Pull the quick
connector carefully.

ON-VEHICLE INSPECTION
1. CHECK ENGINE OIL LEVEL
(a) Warm up the engine, then stop the engine and wait for 5 minutes.
(b) Check that the engine oil level is between the low and full level marks on the level gage.
If low, check for leakage and add oil up to the full level mark.
NOTICE:
Do not fill with engine oil above the full level mark.
2. CHECK ENGINE OIL QUALITY
(a) Check the oil for deterioration, water intrusion, discoloring
or thinning.
If the quality is visibly poor, replace the oil.
Oil grade:
Use API grade SL ºEnergy-Conservingº, or ILSAC
multigrade engine oil.
SAE 5W-30 is the best choice for good fuel economy,
and good starting in cold weather.
If SAE 5W-30 is not available, SAE 10W-30 may be
used.
However, it should be replaced with SAE 5W-30 at the
next oil replacement.
3. INSPECT OIL PRESSURE
(a) Disconnect the oil pressure switch connector.
(b) Using a deep socket wrench 24 mm, remove the oil pres-
sure switch.
(c) Install the oil pressure gauge.
(d) Warm up the engine.
(e) Inspect the oil pressure.
Oil pressure:
At idle29 kPa (0.3 kgf/cm2, 4.3 psi) or more
At 3,000 rpm245 to 539 kPa (2.5 to 5.5 kgf/cm2, 36 to 78 psi)
