Chery Amulet Engine. Manual — part 12

——Coolant draining ：
(1) Remove pressure cap of expansion water tank

(2) Connect a container under the radiator. Remove the outlet hose of radiator or open the drain plug of

radiator.

——Cleaning cooling system：
(1) Drain the coolant and then close the drain plug of radiator or install the outlet hose of radiator
(2) Add clean water into the max water level of expansion tank and install the pressure cap
(3) Start engine and keep idling., warm engine to normal working temperature and stop engine cooling

down.

(4) Drain water
(5) Repeat step (2)—(4) until the water drained is the same as clean water.
(6) If the previous coolant application and replacement is not to specification, do some cleaning as the

following method:

a. Drain coolant
b. Remove outlet hose of radiator. Insert the water supply hose into the inlet of radiator until the water

drained is clean.

c. Connect the hose connected to water supply to the water outlet of thermostat seat to wash the engine

until the water drained from the water pump inlet is clean.

d. If radiator is too dirty, it may be washed from the reverse direction. Connect the hose connected to the

water supply to the water outlet of thermostat seat to wash the engine until the water coming out from
the water pump inlet is clean.

——Add coolant
(1) Before adding coolant, check if the drain plug of radiator is closed and if the pipeline is connected and

tight

(2) Remove the pressure cap and add coolant by the filler of expansion tank slowly. Since the expansion

tank is in the highest point of cooling system, with the coolant level raising, the air in the system will
be discharged into the expansion tank. Adding coolant slowly may discharge the air.

(3) Keep adding coolant until coolant level reaches the “maximum” line. Install the filler cover to avoid

coolant splashing.

(4) Start engine and keep idling. Warm engine to normal working temperature. Fan starts to run. Observe

the water thermometer and check if engine is overheated. If the coolant level of expansion tank drops
quickly, add coolant to the “maximum” line to reduce the air circulation in the system.

(5) Stop engine to cool engine completely (one night if possible). Remove pressure cap and check coolant

level, fill coolant to the “maximum” line.

2) The removal and installation of water pump
assembly
——The structure of water pump assembly
1—water pump case
2—water pump impeller
3—water pump gear
4—water pump bearing

5—water pump seal (ceramics—black lead)

Removal：

——Loosen and remove four bolts from the
front end of cylinder block
——Remove water pump assembly
——Remove sealing gasket of water pump

Installation：
——Install new sealing gasket of water
pump on the water pump
——Install the water pump assembly inside
the cylinder block and screw in four
retaining bolt by hand, then tighten to
7

9 in-lbs.

Note: The water pump assembly may not be
serviced. When water seal or bearing is
damaged, the water pump assembly should
be replaced

3) The removal and installation of thermostat seat with thermostat assembly

——Loosen three M6×40 bolts and remove them
——Remove thermostat seat with thermostat assembly
——Pry out spring clip by chisel or screwdriver








——Take out the thermostat













——Take out sealing gasket
——Remove sealing gasket of thermostat seat

Assembly:

——Clip the thermostat seat, and put the rubber seal ring into the thermostat hole.
——Install the thermostat (with spring outward)
——Install spring clip, ensure that the clip is clipped in the thermostat seat groove.
——Install the sealing gasket of the new thermostat seat on the thermostat assembly with a bolt.
——Install the thermostat together with thermostat assembly into the rear end hole of cylinder head. Finger

screw in 3 bolts and tighten to

88 in-lbs.

——Tighten the hex head plug with the sealing gasket on. Tightening torque is 38-42Nm.
——For the engine equipped with electrical heater, install air intake preheating switch. Tightening torque is

3

0 ft-lbs.

3. Removal and assembly of the water temperature sensor.
Removal:
——Remove the water temperature sensor (at the exhaust side, under the rear lug).

Assembly:

——Before installation, apply the lotite sealant 243 onto the bolt threads. Finger screw in and tighten to

80 in-lbs.
