Cooling System Pressure Test
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.
CAUTION:
Do not pressurize the cooling system beyond the maximum pressure listed in the specifications
table in this section, or cooling system components can be damaged.
1. Turn the engine off.
2. Check the engine coolant level. Adjust the coolant level as necessary.
3. Attach the pressure tester to the coolant recovery reservoir. Install a pressure test pump to the quick-connectfitting of the test adapter.
4. Pressurize the engine cooling system to 111 kPa. Observe the gauge reading for approximately 2 minutes. Pres- sure should not drop during this time. If the pressure drops within this time, inspect for leaks and repair as nec-
essary.
5. If no leaks are found and the pressure drops, the pressure relief cap may be leaking. Install a new pressure relief cap and retest the system.
6. If no leaks are found after a new pressure relief cap is installed, and the pressure drops, the leak may be inter- nal to the radiator transmission cooler (if equipped). Inspect the coolant for transmission fluid and the transmis-
sion fluid for coolant. Repair as necessary.
7. If there is no contamination of the coolant or transmission fluid, the leak may be internal to the engine. Inspect the coolant for engine oil and the engine oil for coolant.
8. Release the system pressure by loosening the pressure relief cap. Check the coolant level and adjust as nec- essary.
Cooling System Concentration Test
CAUTION:
Do not mix types of coolant, corrosion protection will be severely reduced.
Coolant concentration should be checked when any additional coolant is added to the cooling system or after a cool-
ant drain, flush and refill. The coolant mixture offers optimum engine cooling and protection against corrosion when
mixed to a freeze point of -37°C to -46°C. The use of a hydrometer or a refractometer can be used to test coolant
concentration.

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.

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

Exhaust gases contain carbon monoxide which can be harmful to your health and are potentially lethal. Exhaust
system leaks should be repaired immediately. Never operate the engine in enclosed areas. Failure to follow
these instructions may result in personal injury or death.
Operation
In order to reduce vehicle emissions released by the engine, the catalytic converter is required to perform in all oper-
ating conditions. This reduction is especially beneficial during the cold start and warm up phases of operation, which
is when a majority of the tailpipe emissions occur on today’s vehicles because the catalytic converter has not yet
reached its operating temperature. The exhaust system channels exhaust gases from the engine and away from the
vehicle.

Catalytic Converter
Description
The catalytic converter is attached to the exhaust manifold using fasteners and a gasket for sealing.
The catalytic converter plays a major role in the emission control system. The catalytic converter operates as a gas
reactor. Its catalytic function is to speed the heat-producing chemical reaction of components in the exhaust gases in
order to reduce air pollutants.
Operation
Catalyst operation is dependent on its ability to store and release the oxygen needed to complete the emissions-
reducing chemical reactions. As a catalyst deteriorates, its ability to store oxygen is reduced. Since the catalyst’s
ability to store oxygen is somewhat related to proper operation, oxygen storage can be used as an indicator of cat-
alyst performance.
CAUTION:
Unleaded gasoline must be used in order to avoid damaging the catalyst core.
