6. Fuel System
General
The compressed gas [maximum pressure approximately 250 kg / cm
2 (3600 psi, 24.8 MPa) @ 21C
(70F)] from the CNG fuel tank located in the rear section of the vehicle is routed via a fuel filter to the
engine compartment. The pressure of the fuel is then reduced to 8 kg / cm
2 (114 psi, 785 kPa).
A pressure regulator and injectors designed exclusively for CNG application have been adopted.
A fuel pressure sensor and a fuel temperature sensor that are used for the correction of the fuel injection
volume are located on the delivery pipe.
The fuel tank, pressure regulator, and the delivery pipe are provided with shutoff valves that shut off the
fuel when the ignition switch is turned OFF.
In addition, these valves shut off the fuel when the engine stalls, the SRS airbag is deployed, or the pres-
sure in the main pipe becomes abnormally low.
A fuel temperature sensor for the fuel gauge is mounted on the tank valve assembly, and a fuel pressure
sensor is mounted immediately upstream of the pressure regulator.

Fuel Tank
A fuel tank made with carbon fiber and alumi-
num lining has been adopted to prevent weight
increase.
Because the fuel tank expands along with the
increase in the pressure of the compressed gas,
the tank bands contain coil springs to accom-
modate the fluctuation in the perimeter of the
tank.
The fuel tank is provided with a tank valve as-
sembly.
Tank Valve Assembly
1) General
The tank valve assembly is mounted on the
tank and consists of a fuel shutoff valve, inlet
check valve, relief valve and two manual cut-
off valves.

ENGINE OIL INSPECTION
1. CHECK OIL QUALITY
Check the oil for deterioration, entry of water, dis±
coloring or thinning.
If oil quality is visibly poor, replace it.
Oil grade:
API grade SG or SH, Energy Conserving II multi±
grade engine oil or ILSAC multigrade engine oil.
Recommended viscosity is as shown in the illustra±
tion.

ENGINE COOLANT INSPECTION
1. CHECK ENGINE COOLANT LEVEL AT RESERVOIR
TANK
The engine coolant level should be between the
ªLOWº and ªFULLº lines at low temperature.
If low, check for leaks and add engine coolant up to
the ªFULLº
2. CHECK ENGINE COOLANT QUALITY
There should be no excessive deposits of rust or
scales around the radiator cap or radiator filler hole,
and the engine coolant should be free from oil.
If excessively dirty, replace the engine coolant.
2. CHECK ENGINE OIL LEVEL
The oil level should be between the ªLº and ªFº marks
on the dipstick.
If low, check for leakage and add oil up to the ªFº
mark.

3. Delco Battery:
CHECK HYDROMETER
Green Dot visible:
Battery is adequately charged
Dark (Green Dot not visible):
Battery must be charged
Clear or Light Yellow:
Replace battery
HINT: There is no need to add water during the entire
service life of the battery.
AIR FILTER INSPECTION
1. INSPECT AIR FILTER
Visually check that the element is not excessively
dirty, damaged or oily.
2. CLEAN AIR FILTER
Clean the element with compressed air.
First blow air from the inside thoroughly. Then blow
off the outside of the element.B. Except Maintenance Free Battery
Check the specific gravity of each cell.
Standard specific gravity:
55D23L battery for GNB Incorporated
1.25 ± 1.27 at 205C (685F)
55D23L battery for JOHNSON CONTROLS

If the gravity is less than specification, charge the
battery.
HINT: Check the indicator as shown in the illustration.
HIGH±TENSION CORDS INSPECTION
1. DISCONNECT HIGH±TENSION CORDS FROM
SPARK PLUGS
Disconnect the high ± tension cords at the rubber
boot. Do not pull on the high±tension cords.
NOTICE: Pulling on or bending the cords may damage the
conductor inside.

GENERATOR DRIVE BELT INSPECTION
INSPECT DRIVE BELT
(a) Visually check the drive belt for excessive wear,
frayed cords etc.
If any defect has been found, replace the drive belt.
HINT: Cracks on the rib side of a drive belt are consid±
ered acceptable. If the drive belt has chunks missing
from the ribs, it should be replaced.4. INSPECT HIGH±TENSION CORD RESISTANCE
Using an ohmmeter, measure the resistance.
Maximum resistance:
25 k
per cord
If the resistance is greater than maximum, check the
terminals. If necessary, replace the high ± tension
cord.

4. INSPECT VALVE CLEARANCE
(a) Check only the valves indicated.
Using a thickness gauge, measure the clearance
between the valve lifter and camshaft.
Record the out± of ±specification valve clear±
ance measurements. They will be used later to
determine the required replacement adjusting
shim.
Valve clearance (Cold):
Intake
0.19 ± 0.29 mm (0.007 ± 0.011 in.)
Exhaust
0.28 ± 0.38 mm (0.011 ± 0.015 in.) 3. SET NO.1 CYLINDER TO TDC/COMPRESSION
(a) Turn the crankshaft pulley and align its groove with
timing mark ª0º of the No.1 timing belt cover.
(b) Check that the valve lifters on the No.1 cylinder are
loose and valve lifters on the No.4 are tight.
If not, turn the crankshaft one revolution (360*) and
align the mark as above.
(b) Turn the crankshaft one revolution (360
) and align
the mark as above. (See procedure in step 3)
(c) Check only the valves indicated as shown. Measure
the valve clearance. (See procedure in step (a)) HINT: Arrange the grommets in correct order, so that
they can be reinstalled into their original positions.
This minimizes any possibility of oil leakage due to
reuse of grommets.
