DTC Confirmation Procedure:
Before performing the following procedure, confirm that battery voltage is more than 12 V.
• Turn ignition switch off.
• Connect the X-431 scan tool to the Data Link Connector (DLC) - use the most current software available.
• Turn ignition switch on and record and erase DTC.
• Start engine and warm it up to the normal operating temperature.
• Turn ignition switch off and wait at least 10 seconds.
• Start engine and keep the engine speed 2000 RPM for at least 1 minute.
• Let engine idle for 2 minutes, select view DTC and data stream.
• If the DTC is detected, the DTC condition is current. Go to Diagnostic Procedure - Step 1.
• If the DTC is not detected, the DTC condition is intermittent (See Diagnostic Help and Intermittent DTC Trou-
bleshooting in Section 03 Electronic Engine Controls for more information.
NOTE :
While performing electrical diagnosis & testing, always refer to the electrical schematics for specific circuit
and component information.

Operation
The primary purpose of a cooling system is to maintain engine temperature in a range that will provide satisfactory
engine performance and emission levels under all expected driving conditions. It also provides hot coolant for heater
performance and cooling for automatic transmission oil. This is done by transferring heat from engine metal to cool-
ant, moving the heated coolant to the radiator, and then transferring the heat to the ambient air. Engine Coolant Flow Diagram - 1.6L & 1.8L & 2.0L

DIAGNOSIS AND TESTING

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).
