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

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.

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.

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).
