52Chapter 6 Cooling System Inspection
(MR7131A, MR7151A, MR7161A)Section 1 System Check1. Check the cooling system for leakage. See (Figure 118)
(a) Fill coolant into radiator. Install the tester onto the radiator cap port.
(b) Start engine.
(c) The water pump pressure is 118Kpa. Check the pressure and ensure the
pressure will not drop. If the pressure drops, check the port, radiator and
water pump for leakage. If there is no leakage, check the heat exchanger,
cylinder block and cylinder head.
2. Check the engine coolant level in the reservoir.
The coolant level should be between low and full marks.
3. Check coolant quality
(a) Remove radiator cap.
To avoid being scalded, do not remove radiator cap while the engine and
radiator are still hot, as fluid and steam can be sprayed under pressure.
(b) There should not be excessive deposits of rust or scale around the radiator,
and the coolant should be free from oil.
(c) Reinstall the radiator cap.
4. Thermostat
Hint:
The thermostat temp indicates the valve opening temperature.
See (Figure 119).
(a) Immerse the thermostat in water and gradually heat the water.
(b) Check the valve opening temperature. Valve opening temperature: 80 -- 84°C
(c) Check the valve lift. See (Figure 120, Figure 121). Valve lift: 8mm or mor at
95°C
(d) Check the thermostat is fully closed when the thermostat is at low temperature
( 77°C).
5. Radiator cap valve
Standard opening pressure: 93-123kpa
Minimum opening pressure: 78kpa
If the opening pressure is less thanminimum, replace the radiator cap.Figure 118

65g. Ignition system failure;
h. Low engine compression pressure.
(3) Diagnosis and Troubleshooting
a. First, check the fuel tank for fuel level, turn on the ignition switch, if fuel gauge pointer does not
move or fuel level warning lamp lights, then the fuel tank is empty, fuel shall be filled at this time.
b. Check that the electrical fuel pump for operation. Remove the fuel tank, you may use a wire to
connect the two jacks of the fuel pump for short, then turn on the ignition switch. The fuel pump
operation sound shall be able to be heard from the fuel tank nozzle or fuel flow can be felt with hand
pinching the tube; or remove the return hose on the fuel pressure regulator, check that the fuel
flows out; Direct judgment can be made if it is equipped with fuel pressure gage.
If electrical fuel pump is inoperative, check whether the main fuse, main relay, fuel pump relay,
fuel pump control circuit and ECU are OK. If all of them are OK, check fuel pump circuit for open,
short or damaged check valve. Repair or replacement shall be made when problems are found.
c. If there is no injection sound in injector, check injector control circuit for fault. You may use a
testing lamp with big resistance to be connected to the injector wiring connector, turn on the ignition
switch. If the testing lamp lights up, it indicates that the injector has been damaged and shall be
replaced; if the testing lamp does not light up, check whether the main fuse, EFI relay, fuse, ignition
switch and ECU terminal are OK, repair or replace them if they are not OK.
d. If there is low fuel pressure, the injection amount would be small and the engine won't start, you
should check the fuel filter for block and fuel pump safety valve for damage and check whether the
fuel pressure regulator is within the normal range, otherwise those components shall be repaired or
replaced.
e. Electric injection engine normally spot contact start the engine.
f. Check for open in the throttle position sensor (TPS) circuit.
g. Check whether there is Diagnostic Trouble Code (DTC), if there is, check it by the DTC; if there
is not, check the high voltage spark for intensity, if it is too weak, check spark plug, high voltage
wire, high voltage coil, distributor cover for faults, if there are faults, repair or replace them.
h. Check the compression pressure in the cylinder, insert the compression pressure gauge into the
spark plug hole, completely open the throttle, measure the compression pressure while starting the
engine. If the compression pressure is less than 980kPa when engine speed is more than 250r/min,
remove and inspect the engine and troubleshoot it.
3. The engine cranks but can not start
(1) Symptom
When starting the engine, starter can crank the engine but fail to start the engine.
(2) Causes:
a. Ignition advance angle is unfavorable;
b. Ignition is out of sequence, there is misfire;
c. High voltage spark is too weak;
d. The fuel pressure is too low;
e. fuel pressure regulator leakage;

66f. The idle control valve is faulty;
g. The water temperature sensor is damaged;
h. The vacuum pressure sensor is damaged;
i. The air filter is blocked;
j. The injector leaks;
k. The compression pressure in the cylinder is too low;
l. The intake temperature sensor is damaged.
(3) Diagnosis and Troubleshooting
a. Check high pressure spark, check whether the high pressure spark on the ignition coil high pressure
bus and extension are OK, if the bus spark is week, replace the ignition coil, if the bus spark is OK
while the extension spark is too week, replace the ignition coil also; In addition, excessive spark
plug clearance will influence the starting feature, the clearance of the spark plug shall be adjusted
to normal value (0.8±0.1mm);
b. If there is low fuel pressure, check whether the battery voltage is OK, otherwise it shall be
troubleshot or replaced; check fuel pump check valve for leakage, check fuel filter and fuel pipe for
block, if there are leakage or block, replace or troubleshoot them;
c. If there is leakage for fuel pressure regulator, intake manifold is likely to be mixed with gasoline and
it is hard to start, troubleshoot or replace them;
d. Idle control valve can not be opened to maximum position due to mechanical wear, aging or control
circuit failure, the idle control valve shall be replaced and the control circuit failure shall be troubleshot;
e. If the water temperature sensor data is not accurate, it may cause small injection, check the water
temperature sensor based on the standard data and calibrate the data;
f. There is big time lag for intake pressure temperature sensor that makes it somewhat insensitive at
low speed and result in inaccurate injection, adjustment or replacement shall be made;
g. If the air cleaner filter is too dirty, the air flow resistance is excessively big, resulting in hard start,
as a result of it, the filter shall be replaced.
In a word, there are many factors causing the starting failure of the engine, analysis shall be made based on
the severe conditions of the faults. Generally speaking, check the ignition system first, then check intake
system, fuel system, control system, at last check the cylinder pressure, check the DTC before checking the
trouble. The diagnosis and troubleshooting procedures for starting failure of the engine are shown in (Figure
148).

68d. Fuel pressure system abnormal;
e. Idle control valve fault;
f. Vacuum pressure sensor fault;
g. Ignition system fault;
h. The compression pressure in the cylinder is a little lower;
i. Injector leakage.
3. Diagnosis and Troubleshooting
a. Perform self-diagnosis first, check whether there is any DTC, if there is, find the reason and cause by the
DTC;
b.If it is hard for cold start but easy for hot start, check water temperature sensor and intake temperature
sensor for fault;
c. If the engine can not be started quickly in hot condition, the relief of the fuel pressure will be fast, then
repair and replacement shall be made;
d. If the spark is too weak, check high pressure coil, spark plug clearance and spark plug for carbon deposit,
repair or replace them one by one after isolating the problem;
e. Intake and exhaust valve is not completely closed, piston ring failure is likely to cause low compression
pressure in the cylinder, you should carefully repair intake & exhaust valve and seat, or replace them;
failed piston ring shall be replaced.
4. Diagnosis and Troubleshooting for hard starting and trouble shooting procedure. (Figure 149)III. Fuel Pipeline and Circuit Faults for Poor Engine OperationPoor engine operation includes: insufficient power, poor acceleration, poor deceleration, big fuel consumption,
rough idle and Engine overheat.
1. Insufficient Power
(1) Symptom:
Engine operation is normal without load but slow at load, insufficient power when uphill and not improved
even if the accelerator pedal is completely depressed, speed can not be increased and unable to reach the
maximum vehicle speed.
(2) Causes:
a. Air cleaner is clogged;
b. Poor intake system seal;
c. Intake pressure temperature sensor fault;
d. Low fuel pressure;
e. Broken pressure adjustor;
f. Clogged injector or poor atomization;
g. Throttle position sensor fault;
h. High pressure spark is too weak;
i. Improper valve clearance;
