2004 CHRYSLER VOYAGER OUTLET

OIL PUMP
DESCRIPTION
The oil pump is located in the pump housing inside
the bell housing of the transaxle case (Fig. 283). The
oil pump consists of an inner and outer gear, a hous-
ing, and a cover that also serves as the reaction shaft
support.
OPERATION
As the torque converter rotates, the converter hub
rotates the inner and outer gears. As the gears
rotate, the clearance between the gear teeth
increases in the crescent area, and creates a suction
at the inlet side of the pump. This suction draws
fluid through the pump inlet from the oil pan. As the
clearance between the gear teeth in the crescent area
decreases, it forces pressurized fluid into the pump
outlet and to the valve body.
DISASSEMBLY
When disassembling the transaxle it is necessary
to inspect the oil pump for wear and damage.
(1) Remove the reaction shaft support bolts.
(2) Remove reaction shaft support from pump
housing (Fig. 284).
(3) Remove the pump gears (Fig. 285) and check
for wear and damage on pump housing and gears.
(4) Re-install the gears and check clearances.
(5) Measure the clearance between the outer gear
and the pump pocket (Fig. 286). Clearance should be
0.089±0.202 mm (0.0035-0.0079 in.).
(6) Measure clearance between outer gear and
crescent. Clearance should be 0.060-0.298 mm
(0.0023-0.0117 in.).
(7) Measure clearance between inner gear and
crescent. Clearance should be 0.093-0.385 mm
(0.0036-0.0151 in.).
(8) Position an appropriate piece of Plastigage
across both pump gears.

OIL PUMP
DESCRIPTION
The oil pump is located in the pump housing inside
the bell housing of the transaxle case (Fig. 255). The
oil pump consists of an inner and outer gear, a hous-
ing, and a cover that also serves as the reaction shaft
support.
OPERATION
As the torque converter rotates, the converter hub
rotates the inner and outer gears. As the gears
rotate, the clearance between the gear teeth
increases in the crescent area, and creates a suction
at the inlet side of the pump. This suction draws
fluid through the pump inlet from the oil pan. As the
clearance between the gear teeth in the crescent area
decreases, it forces pressurized fluid into the pump
outlet and to the valve body.
DISASSEMBLY
When disassembling the transaxle it is necessary
to inspect the oil pump for wear and damage. (1) Remove the reaction shaft support bolts.
(2) Remove reaction shaft support from pump
housing (Fig. 256). (3) Remove the pump gears (Fig. 257) and check
for wear and damage on pump housing and gears. (4) Re-install the gears and check clearances. (5) Measure the clearance between the outer gear
and the pump pocket (Fig. 258). Clearance should be
0.089±0.202 mm (0.0035-0.0079 in.). (6) Measure clearance between outer gear and
crescent. Clearance should be 0.060-0.298 mm
(0.0023-0.0117 in.). (7) Measure clearance between inner gear and
crescent. Clearance should be 0.093-0.385 mm
(0.0036-0.0151 in.).

CONDITIONING
DESCRIPTION
DESCRIPTION - ENGINE COOLING SYSTEM
REQUIREMENTS
To maintain the performance level of the heating,
ventilation and air conditioning (HVAC) system, the
engine cooling system must be properly maintained.
The use of a bug screen is not recommended. Any
obstructions in front of the radiator or condenser will
reduce the performance of the air conditioning and
engine cooling systems.
The engine cooling system includes the radiator,
thermostat, radiator hoses and the engine coolant
pump. Refer to Cooling for more information before
opening or attempting any service to the engine cool-
ing system.
DESCRIPTION - HEATER AND AIR
CONDITIONER
A manually controlled single zone type heating-air
conditioning system, manually controlled dual zone
type heating-air conditioning system, manually con-
trolled three zone type heating-air conditioning sys-
tem or an automatic controlled three zone typeheating-air conditioning system is available on this
model.
All vehicles are equipped with a common heater,
ventilation and air conditioning (HVAC) housing (Fig.
1). The system combines air conditioning, heating,
and ventilating capabilities in a single unit housing
mounted within the passenger compartment under
the instrument panel. The HVAC housing includes:
²Blower motor
²Blower motor resistor block or power module
(depending on application)
²Heater core
²Evaporator coil
²Blend door and actuator
²Mode door and actuator
²Recirculation door and actuator
Based upon the system and mode selected, condi-
tioned air can exit the HVAC housing through one or
a combination of the three main housing outlets:
defrost, panel or floor. The defrost and panel outlets
are located on the top of the housing and the floor
outlet is located on the bottom of the housing. Once
the conditioned air exits the unit housing, it is fur-
ther directed through molded plastic ducts to the var-
ious outlets in the vehicle interior. These outlets and
their locations are as follows:
²Defroster Outlet- A single large defroster out-
let is located in the center of the instrument panel
top cover, near the base of the windshield.
²Side Window Demister Outlets- There are
two side window demister outlets, one is located at
RSHEATING & AIR CONDITIONING24-1

each outboard end of the instrument panel, near the
A-pillars.
²Panel Outlets- There are five panel outlets in
the instrument panel, one located near each outboard
end of the instrument panel facing the rear of the
vehicle and three located near the top of the instru-
ment panel center bezel.
²Front Floor Outlets- There are two front floor
outlets, one located above each side of the center of
the floor panel near the dash panel.
DESCRIPTION - SINGLE ZONE
A single zone heating and air conditioning system
allows one temperature setting for the entire vehicle.
The full range of temperatures that the system can
produce are available by rotating the temperature
control located in A/C-heater control.
The A/C-heater control and integral computer is
located in the instrument panel and contains:
²a rear window defogger on/off switch. Contains
an LED that illuminates to show when the function
is operational.
²an air recirculation on/off switch. The Recircu-
late button contains an LED that illuminates to show
when the function is in operation.
²an air conditioning on/off switch. The Snowflake
button contains an LED that illuminates to shown
when the function is in operation.
²a rotary knob for fan speed selection and turn-
ing the heater-A/C system off.
²a rotary knob for temperature control of the dis-
charged air.
²a rotary knob for mode control.
DESCRIPTION - DUAL ZONE
The manual dual zone heating and air conditioning
system allows completely independent side-to-side
temperature control of the discharge air.
The A/C-heater control and integral computer is
located in the instrument panel and contains:
²a rear window defogger on/off switch. Contains
an LED that illuminates to show when the function
is operational.
²slide controls for completely independent side-to-
side temperature control of the discharged air. The
full range of temperature that the system can pro-
duce in any mode is available on either side of the
vehicle by independently positioning the slide con-
trols on the instrument panel.
²an air recirculation on/off switch. The Recircu-
late button contains an LED that illuminates to show
when the function is in operation.
²an air conditioning on/off switch. The Snowflake
button contains an LED that illuminates to shown
when the function is in operation.
²a rotary knob for fan speed selection and turn-
ing the heater-A/C system off.
²a rotary knob for mode control.
DESCRIPTION - MANUAL THREE ZONE
The fully adjustable manual three zone front and rear
heating and air conditioning system allows intermediate
seat passengers the ability to regulate air temperature
as well as fan speed and provides floor outlets to the
rear of the right sliding door and overhead outlets at
each rear outboard seating position. Primary control for
the rear blower is on the front A/C-heater control. All
controls are identified by ISO graphic symbols.
FRONT CONTROL PANEL
The front A/C-heater control and integral computer
mounted in the instrument panel contains:
²a rear window defogger on/off switch.
²slide controls for completely independent side-to-
side temperature control of the discharge air. The full
range of temperature that the system can produce in
any mode is available on either side of the vehicle by
independently positioning the slide controls on the
instrument panel.
²an air recirculation button. The Recirculate but-
ton contains an LED that illuminates to show when
the function is in operation.
²an air conditioning button that allows the com-
pressor to be turned on/off. The Snowflake button
contains an LED that illuminates to shown when the
function is in operation.
²a rotary knob for front fan speed selection and
turning the heater-A/C system off.
²a rotary knob for rear fan speed selection.
²a rotary knob for mode control.
