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

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

Notes:
The temperature indicated on the thermostat is marked as open
temperature of the valve (see Figure 5-2).
(1) Submerge the thermostat into water and heat gradually.
(2) Check the open temperature of the valve.
Open temperature of the valve: 80-84°C
(3) Check the lift of the valve (see Figure 5-3 and Figure 5-4).
