Section 3 Valve Clearance AdjustmentAdjust the throttle gap (see Figure 2-9).
Calculate the thickness of new washer to allow the
gap of the exhaust valve to reach a specified value.
N=T+(A-0.2mm)
Note: where,
N -- Thickness of new washer
T -- Thickness of the washer removed
A -- Measured throttle gap
Calculation formula of the suction valve is: N= T+(A-0.3mm).
(1) Remove the adjusting washer.
a. Rotate the crankshaft until the top of the cam is upwards.
b. The nick of the valve tappet faces toward the front.
c. Press the valve tappet down with a special tool, and place
the tool between the camshaft and the valve tappet (see
Figure 2-10).
Tip:
Place one end, with a mark "9", of the special tool to the position
shown in Figure 1-24 a bit aslant.

If the special tool (B) is put into a deep position too much, it will
be clipped by the washer. In order to avoid the special tool (B) being
too hard to take out, put it into slowly by decreasing the inclination
angle from the suction side.
It is difficult for the special tool (B) to insert due to the shape
of the cam when inserting it from the suction side to the back side of
No.3 cylinder (see Figure 2-10). When adjusting the washer, therefore,
it is advisable to insert from the exhaust side.
d. Press the valve tappet down alternately with the special tool
(A) and (B) to check the throttle gap.
(2) Re-mount the adjusting washer.
a. Mount a new adjusting washer on the valve tappet.
b. Press the valve tappet down with the special tool (A), and
remove the special tool (B).
c. Re-check the throttle gap.Figure 2-9

Chapter 3 Fuel SystemSection 1 Check Fuel System PressureOn-board inspection
1. Check the operation of the fuel pump.
(1) Connect the positive and the negative of the battery to
appropriate connector sockets of the fuel pump (see Figure 3-1).
Attention: Do not start the engine.
If there is pressure present, you will hear that the fuel is flowing.
If there is no pressure present, check the fusible cutout, fuse, EFI
open-circuit relay, fuel pump, ECM (Electronic Control Module) and
circuit joint.
(2) Turn the ignition switch to "OFF".
2. Check the pressure of the fuel.
(1) Check whether the battery voltage is more than 12V.
(2) Disconnect the negative wiring cable from the battery.
(3) Mount a pressure gauge on the fuel input pipe
(see Figure 3-2).
(4) Connect the negative terminal of the battery.
(5) Measure the fuel pressure.
Fuel oil pressure: 265-304kPa
If the pressure is low, check the fuel pipe and connection,
fuel pump, and fuel filter. If the pressure is too high,
replace the regulator.
(6) Start the engine. Measure the fuel pressure at idle speed. The
fuel pressure is 265-304KPa. If the pressure is unsatisfactory, checkFigure 3-1
Figure 3-3 Figure 3-2Fuel SystemCheck Fuel System Pressure3-15the fuel pump, pressure regulator, and injector, and replace if necessary.
(7) After shutting down the engine, check the fuel pressure and
keep the specified pressure for about 5 minutes. The fuel pressure is:
147KPa.
3. The fuel oil pressure regulator (DR) (see Figure 3-3).
Mounting position: On the distributing pipe for fuel.
Faults: Too low or too high fuel pressure, or hard to start.
General causes: Using poor fuel for a long time results in: 1.
strainer blocked; 2. serious leakage caused by particles and impurities.
Other reasons: Man-made mechanical damage, etc.
Maintenance precautions: During maintenance: 1. Never impact the diaphragm element with high pressure
gas; 2. Never clean it with aggressively corrosive liquid; 3. No distortion caused by external force.
Easy measuring method: For the system with oil return, connect a pressure gauge for the fuel on the suction
pipe, start the engine, and run at idle speed. Now, the fuel pressure in the engine should be about 260KPa; pull out
the vacuum pipe of the fuel pressure regulator, and the pressure should be 300KPa approximately.Battery

Section 4 Fuel Emission Control SystemOn-board Inspection1. Check the operation when disconnecting the fuel supply.
(1) Warm the engine up to 2,500r/min at least, and check the noise of the injector with a sound level meter
(see Figure 3-9).
(2) When the throttle releases, the noise from the injector should stop immediately; repeat several times.
2. Check the fuel vapor discharge control system (see Figure 3-10).
(1) After starting the engine, disconnect the vacuum pipe.
(2) Make sure that there is vacuum present at the canister control valve (TEV) port when selecting ”ACTIVE
TEST" and "PURGE TEV" based on the display on the fault diagnosis instrument.
(3) After "ACTIVE TEST", connect the vacuum pipe.
(4) Carry out "ECM DATA MONITOR" on the fault diagnosis instrument, and then select "PURGE TEV"
for operation inspection.
(5) Start up the car after the engine warms up, and make sure the TEV ON from OFF (see Figure 3-11).
3. Check whether there is any distortion or damage on the filling cap and the washer (see Figure 3-12).Figure 3-9 Figure 3-10Fuel SystemFuel Emission Control System3-18Figure 3-11 Figure 3-12Sound level meter

2. Check the engine coolant quantity in the compensating tank.
The coolant level should be between LOW and FULL.
3. Check the coolant quality.
(1) Remove the radiator cover.
Do not remove the radiator cover when the engine and the radiator are still hot in order to avoid scalding
since the liquid vapor may inject.
(2) Check whether there are excessive deposit and rust or sundries around the radiator cover. The coolant is
not allowed to contact with oil.
(3) Remount the radiator cover.Chapter 5 Cooling SystemSection 1 System Inspection1. Check leakage in the cooling system (see Figure 5-1).
(1) Fill coolant in the radiator, and mount the tester at the radiator
cover port.
(2) Start the engine.
(3) Keep the pump pressure at 118KPa without drop. If the
pressure drops,check whether there is any leakage at the port,
radiator and water pump; if not, check the heating core,
cylinder and cap.Figure 5-1
