2008 GEELY MK water pump

2-13For servicing items whose deadlines have expired, they should be maintained at the same intervals as before. The
intervals are recorded in maintenance schedule.
Rubber hoses
Used in cooling and heating system, braking and fuel-feeding systems should be inspected by qualified Geely
technicians according to Geely maintenance schedule.
There are all very important maintenance items. Hoses must be replaced immediately should there be any aging
or damage. Please pay attention, rubber hoses age as time goes by, and they may have problems of inflation, wear,
or crack.

TableEngine AssemblyEngine Inspection3-2 Note:
Check the belt distortion at the specified point (see Figure 1-1).
When mounting a new belt, set the tensioning force to specified value.
After the belt has been operated more than 5 minutes, check and ensure the distortion not exceeding specified
value. (2) Make sure that the coolant level is above the neck of the radiator.
(3) Put the radiator cover in place, pressurize to 2.0Mpa, and keep the pressure for 1minute unless the coolant
leaks. (Mount a tester on the radiator cover, start the engine, and then shut down under a pressure 2.0Mpa).
(4) Check whether the coolant quantity in the dilatation can is between the mark "Low" and "Full".
(5) Check whether the radiator cover is clean; test whether the opening pressure of the main valve is 107.8KPa
with a radiator cover tester. The minimum opening pressure is 58.5KPa.
6. Check the battery.
(1) The terminal voltage of the battery is 12.5-12.9V at 20°C, and charge when the voltage value is less than
the specified value. Check whether the fusible cutout and the fuse are loose, corrosive or on.
7. Check the air filter.
(1) Whether the cover, the case or the element of the filter is distorted, corroded or damaged.
(2) Whether the air hose is damaged.
(3) Whether the air chamber is distorted or damaged.
(4) Whether the air filter element is blocked, polluted or damaged. If the filter element is blocked slightly,
remove the dirt by blowing the element from above.
(5) Whether there is any pollutant or dirt on the air filter support.
8. Check the spark plug.
(1) Spark generation.
a. Disconnect the coupling of the injector.
b. Remove the spark plug from the secondary wire.
c. Remove the spark plug.
d. Connect the spark plug to the secondary wire.
e. Ground the spark plug.
f. Start the engine, and check whether spark is generated.
Prompt: The starting time is not more than 1-2s.
(2) Clean the spark plug: The air pressure is not greater than 588kp and the time is not more than 20s.
(3) Check whether the thread and the insulator of the spark plug are damaged. Replace if necessary.
(4) Check the electrode gap of the spark plug: 0.8±0.1mm for MR479Q and MR479QA; 1±0.05mm for
MR481QA.

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).

be generated.
(1) Firstly turn off meter valve high low manual valve, connect
pipeline according to the figure below, then adjust air conditioner to
maximum refrigeration operating condition, adjust engine speed to
1000 - 2000 r/min, run for 5 min. Circulate refrigerant and collect
residual oil in parts as far as possible into compressor.Symptom Possible cause Diagnosis Correct treatment (2) Loosen throttle, let engine restore to normal idle speed, turn off engine.
(3) Slowly open high voltage manual valve,cover a white towel on hose outlet,observe whether there is oil stain
on the towel, adjust flow of refrigerant.
(4) When high pressure gauge reading decreases to below 0. 35MPa, slowly open low pressure manual valve.
Close manual valve until reading of high low pressure gauge is zero.Fill-up of refrigerant (1) Use vacuum pump to vacuumize the system
During repair of refrigerating system, once refrigerating system is exposed to air or certain refrigerating
system part is to be replaced, automobile air conditioner must be vacuumized. So as to eliminate air and
water vapour in the system.

Symptom
Poor idle speed, malfunction etc
Symptom
Fail to start5-125 Repair precautions:
1. according to engine requirement, electric fuel pumps with different flows are available, they have the same
appearance, mountable fuel pump may not be exactly suitable, during repair, part number of fuel pump used must
be consistent with original one, wrong replacement is not permitted;
2. in order to prevent fuel pump from damaging, please do not run it in dry state for a long time;
3. in case fuel pump needs to be replaced, please pay attention to clean fuel tank and pipeline and replace fuel
filter.
(2) Simple measuring method:
(Remove joint) turn digital multimeter to ohm position, connect two meter pens with fuel pump pins
respectively, measure internal resistance, it should not be zero or infinite (namely not in short circuit, open circuit
condition).
(Connect joint) connect fuel pressure gauge on sucker, start up engine, run the engine at idle speed, now fuel
pressure of engine should be about 260kPa; unplug fuel pressure regulator vacuum tube, now fuel pressure should
be about 300KPa.
11. Canister control valve
(1) Canister in fuel evaporation control system adsorbs oil vapor from oil tank until saturated. Electronic
control unit controls opening of canister control valve, fresh air and saturated fuel vapor in canister form
regeneration stream, which is led into engine intake pipe again. Electronic control unit changes duty ratio of pulsing
signal to canister control valve solenoid according to different operating conditions of engine, thus controls flow
of regeneration stream. In addition, this flow is also influenced by pressure difference at both ends.
Possible cause
Entering of foreign matter into valve inside results in
corrosion or poor leak tightness etc
Repair precautions:
1. To install, airflow direction must meet the specification;
2. when black granules inside valve body result in malfunction of control valve, and control valve needs to be
replaced, please check the condition of canister;
3. avoid water, oil etc liquids from entering valve as far as possible during repair;
4. in order to avoid transfer of solid-borne noise, it is recommended to install canister control valve suspending
on the hose or use soft rubber to fix.
(2) Simple measuring method:
(Remove joint) turn digital multimeter to ohm position, connect two meter pens with canister control valve pins
respectively, rated resistance at 20°C is 22 - 30 ohm.
12. Ignition coil
(1) When earthing channel of primary winding is connected, this primary winding is charged. Once ECU cut
off primary winding circuit, charging stops, high voltage is induced in secondary winding at the same time, so spark
plug discharges. Ignition coil ZSK 22 (both ends of 2 secondary windings are connected with a spark plug
respectively, so these two spark plugs ignite simultaneously.
Possible cause
Too heavy current leads to burnout, damaged by external force Repair precautions: it is prohibited to use "short circuit ignition testing method" to test ignition function, soEngine EFI System-
