Cooling System Draining and Filling
Cooling System Draining Procedure
WARNING!
Never remove the pressure relief cap, under any conditions, while the engine is operating or hot. Failure to fol-
low these instructions could result in personal injury or damage to the cooling system or engine. To avoid hav-
ing scalding hot coolant or steam blow out of the cooling system, use extreme care when removing the pressure
relief cap. Wait until the engine has cooled, then wrap a thick cloth around the pressure relief cap and turn it
slowly one turn (counterclockwise). Step back while the pressure is released from the cooling system. When you
are certain all the pressure has been released, using a cloth turn and remove the pressure relief cap. Failure to
follow these instructions may result in serious personal injury.
Perform the following procedure when draining the cooling system.1. Do not remove the pressure cap first.
2. With the engine cold, remove the pressure cap.
3. Raise and support the vehicle and locate the radiator drain plug.
4. Attach one end of a hose to the drain plug (1). Put the other end into a clean container. Open the
drain plug and drain the coolant from the radiator.
5. Tighten the radiator drain plug.
Cooling System Filling Procedure
CAUTION:
Failure to purge air from the cooling system can result in an overheating condition and severe
engine damage.

Downloaded from www.Manualslib.com manuals search engine Perform the following procedure when filling the cooling system.1. Fill the system using the proper mixture of anti- freeze/coolant and water. Fill the coolant recovery
reservoir to the MAXline and install the pressure
cap.
2. With the heater control in the HEAT position, start and operate the engine with coolant recovery reservoir cap in place.
3. Add coolant to the coolant recovery reservoir as necessary. Only add coolant to the coolant recovery reservoir when the engine is cold. Coolant level in a warm engine will be higher due to thermal expansion.
Thermostat
Description
The thermostat is located in the thermostat housing. The thermostat housing is located on the top of the engine
between the engine and the radiator.
Operation
The thermostat controls the operating temperature of the engine by controlling the amount of engine coolant flow to
the radiator. The thermostat opens when the engine coolant temperature is approximately 90°C. At this temperature,
engine coolant is allowed to flow to the radiator. The thermostat provides quick engine warm up and overall temper-
ature control. The thermostat begins to close below 90°C. The thermostat controls this by the use of a wax pellet
located in a sealed container at the spring end of the thermostat. When heated, the pellet expands and overcomes
the closing spring tension to force the valve to open, and when cooled, the pellet contracts and the closing spring
then forces the valve to close.
Removal & Installation - 1.6L & 1.8L & 2.0L
WARNING!
Always allow the engine to cool before opening the cooling system. Do not remove the coolant pressure relief
cap when the engine is operating or the cooling system is hot. The cooling system is under pressure; steam and
hot liquid can come out forcefully when the cap is loosened slightly. Failure to follow these instructions may
result in serious personal injury.
1. Drain the cooling system (See Cooling System Draining Procedure in Section 06 Cooling System).

Coolant Pump Inspection
Check coolant seal of the coolant pump for coolant leak. If coolant pump bearing is loose, replace the assembly.
Radiator
Description
The radiator is a cross-flow type (horizontal tubes) with design features that provide greater strength, as well as
sufficient heat transfer capabilities to keep the engine coolant within operating temperatures.
Operation
The radiator functions as a heat exchanger, using air flow across the exterior of the radiator tubes. Heat from the
coolant is then transferred from the radiator into the moving air.

The radiator cooling fan operation is controlled by the Engine Control Module (ECM) and the fan relays, with inputs
from the following:
•Engine coolant temperature
• Automatic transaxle fluid temperature (with DP0 transaxle)
• A/C signal
Inspect the cooling fan for proper low speed and high speed operation:
• The low speed fan should be switched on at 98°C and switched off at 94°C.
• The high speed fan should be switched on at 105°C and switched off at 101°C.
• If the water temperature is greater than 101°C after the fan is switched off, the fan will continue to operate for
1 minute.
• If the water temperature is greater than 94°C after the fan is switched off, the fan will continue to operate for
0.5 minute.
• If the water temperature is less than 85°C after the fan is switched off, the fan will stop operating.

Description
This vehicle is equipped with a common HVAC housing assembly. The system combines air conditioning, heating,
and ventilating capabilities in a single unit housing mounted under the instrument panel. The driver can choose the
following functions from HVAC control panel:
•The inside temperature
• The speed of the blower
• Five different modes of operation
• A/C compressor clutch operation
• Recirculation door position
NOTE :
To maintain the performance level of the heating, ventilation and air conditioning (HVAC) system, the engine cooling
system must be properly maintained. Any obstructions in front of the radiator or A/C condenser will reduce the per-
formance of the A/C and engine cooling systems.
13–2Chery Automobile Co., Ltd.

Downloaded from www.Manualslib.com manuals search engine •Use only refrigerant oil of the type recommended for the A/C compressor in the vehicle.
• Recharge the A/C system (See A/C System Evacuation and Recharge in Section 13 Heating & Air Condition-
ing).
Evaporator
Description
The evaporator core is located in the HVAC housing, under the instrument panel. The evaporator coil is positioned in
the HVAC housing so that all air that enters the housing must pass over the fins of the evaporator before it is dis-
tributed through the system ducts and outlets. However, air passing over the evaporator core fins will only be con-
ditioned when the compressor is engaged and circulating refrigerant through the evaporator coil tubes.
Operation
Refrigerant enters the evaporator from the orifice tube as a low-temperature, low-pressure liquid. As air flows over
the fins of the evaporator, the humidity in the air condenses on the fins, and the heat from the air is absorbed by the
refrigerant. Heat absorption causes the refrigerant to boil and vaporize. The refrigerant becomes a low-pressure gas
before it leaves the evaporator. The evaporator core housing directs airflow from the blower motor through the evap-
orator core and heater core. All airflow from the blower motor passes through the evaporator core. The airflow is then
directed through or around the heater core by the temperature blend door(s).
Removal & Installation
1. Evacuate the A/C system (See A/C System Evacuation and Recharge in Section 13 Heating & Air Conditioning).
2. Remove the expansion valve.
3. Remove the HVAC housing (See HVAC Housing Removal and Installation in Section 13 Heating & Air Condi-
tioning).
4. Remove the retaining bolts and screws.
5. Remove the evaporator core.
6. Installation is in the reverse order of removal.
Installation Notes:
• Lubricate new rubber O-ring seals with clean refrigerant oil and install them and new gaskets onto the refriger-
ant line fittings.
• Use only the specified O-rings as they are made of a special material for the R-134a system.
• Use only refrigerant oil of the type recommended for the A/C compressor in the vehicle.
• Recharge the A/C system (See A/C System Evacuation and Recharge in Section 13 Heating & Air Condition-
ing).
Condenser
Description
The condenser is located in the air flow in front of the engine cooling radiator. The condenser transforms the refrig-
erant from a gas into a liquid. It is attached to the vehicle with bolts and the A/C lines with fittings.
Operation
When the heat is removed from the refrigerant, it condenses. When the refrigerant leaves the condenser, it becomes
a high-pressure liquid refrigerant. The volume of air flowing over the condenser fins is critical to the proper cooling
performance of the air conditioning system. Therefore, it is important that there are no objects placed in front of the
radiator grille openings in the front of the vehicle or foreign material on the condenser fins that might obstruct proper
air flow. Also, any factory-installed air seals or shrouds must be properly reinstalled following radiator or condenser
service.
