Engine Coolant Temperature (ECT) Sensor
Description
The Engine Coolant Temperature (ECT) Sensor is beside the thermostat. The ECT Sensor is a negative thermal
coefficient sensor.
Operation
The ECT sensor provides an input signal to the ECM. As temperature increases, resistance of the sensor decreases.
As coolant temperature varies, the ECT sensor resistance changes resulting in a different voltage value at the ECT
sensor signal circuit. The ECM uses the input to control air-fuel mixture, timing, and radiator fan on/off times.
Removal & Installation
1. Disconnect and isolate the negative battery cable.
2. Release the coolant system pressure.
WARNING!
Never remove the radiator pressure relief cap under any conditions while the engine is operating or hot. Failure
to follow these instructions could result in personal injury or damage to the cooling system or engine. To avoid
having scalding hot coolant or steam blow out of the cooling system, use extreme care when removing the pres-
sure 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, (with a cloth) turn and remove the pressure relief cap. Failure
to follow these instructions may result in serious personal injury.
3. Disconnect the coolant temperature sensor electrical connector.
CAUTION:
Remove the coolant temperature sensor when the engine is cold.

Downloaded from www.Manualslib.com manuals search engine The cooling system regulates engine operating temperature. It allows the engine to reach normal operating temper-
ature as soon as possible, maintains normal operating temperature and prevents overheating.
The cooling system also provides a means of heating the passenger compartment. The cooling system is pressurized
and uses a centrifugal water pump to circulate coolant throughout the system.
The cooling system consists of the following components:
•Radiator
• Coolant
• Coolant pump
• Electric cooling fans
• Electric cooling fans control module
• Thermostat
• Coolant reservoir

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).
