WATER TEMPERATURE SENSOR

Disassembly:
——To demount water temperature sensor (at the

exhaust pipe flank and under the lifting eye).

Assembly:
——To apply Letai 243 glue on the screw thread,

screw up the bolt to 7.0—10.0Nm before
installation.

Checking:

Water temperature sensor is a negative temperature coefficient sensor, which is composed of

a thermal resistor. The resistance value of the resistor shall decrease as the engine temperature
rises. The variation is detailed in the following table:

COOLING FAN

Disassembly:

——To disconnect the negative terminal of battery;

——To demount the matching plug of the cooling fan.

——To remove the fastening self-tapping screw from

the cooling fan.

——To take the cooling fan out.

Assembly:

——To assemble the cooling fan according to the

disassembly order (the tightening torque of
self-tapping screw is 1.8~2.2Nm)

——To start up the engine and check if the cooling fan

is under normal operation.

Guideline For Disassembly:

——During the disassembly process, you should pay

more attention not to pull A/C pipe to a large extent,
otherwise the A/C pipe shall crack and deform.

EXPANSION RESERVOIR

——To pry out the protecting hood of expansion

reservoir by using a screw drive.

——To demount the fastening bolts of the expansion

reservoir by using M10 sleeve.

——To pull out the plug of liquid level sensor.

——To take the expansion reservoir out.

Disassembly:

——To demount the water pipe connecting with the

expansion reservoir.

——To demount the left and right wind boards by M10

sleeve.

——To take out the radiator.

Assembly:

——To assemble the expansion reservoir according to

the order opposite to the disassembly order（the
tightening torque of self-tapping screw is
4.0~5.0Nm）.

——To refill coolant.

ASSEMBLY OF RADIATOR

Disassembly:

——To discharge coolant (refer to the coolant discharge

process)

——To demount the cooling fan (refer to the

disassembly process of the cooling fan).
