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 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.

Wheel Assembly
Description
Original equipment wheels are designed for operation up to the specified maximum vehicle capacity.
Inspect wheels for the following:
•Dents or cracks
• Damaged wheel bolt holes
• Air leaks from any area or surface of the rim
• Excessive run out
NOTE :
Do not attempt to repair a wheel by hammering, heating or welding.
NOTE :
The wheel nuts are designed for specific applications. Do not use replacement bolts with a different design or lesser
quality.
Removal & Installation
1. Raise and support the vehicle.
2. If the vehicle is equipped with wheel center caps that cover the wheel nuts, remove the cap with an appropriate removal tool utilizing the notch located between the wheel and the outer edge of the cap.
NOTE: Use care not to damage the finish on the wheel.
3. Remove the wheel mounting nuts (2) with a suit- able tool and remove the wheel assembly (1).
(Tighten: Wheel mounting nuts to 110 N·m)
4. Installation is in the reverse order of removal.
Wheel Balance
Description
Balance the wheel assembly as necessary following the wheel balancer manufacturer’s instructions.
• Road test the vehicle for at least 5 miles.
• If the vibration persists, continue with Diagnosis & Testing procedure.

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.
