Removal; Installation; Liquid Line Removal - Dodge Dakota Sport 2001 Service Manual

AN
HEATER CORE (Continued)
allows control of the heater output air temperature
by controlling how much of the air flowing through
the HVAC housing is directed through the heater
core. The blower motor speed controls the volume of
air flowing through the HVAC housing.
The heater core cannot be repaired and, if faulty or
damaged, it must be replaced.

REMOVAL

WARNING: ON VEHICLES EQUIPPED WITH AIR-
BAGS, DISABLE THE AIRBAG SYSTEM BEFORE
ATTEMPTING ANY STEERING WHEEL, STEERING
COLUMN, OR INSTRUMENT PANEL COMPONENT
DIAGNOSIS OR SERVICE. DISCONNECT AND ISO-
LATE THE BATTERY NEGATIVE (GROUND) CABLE,
THEN WAIT TWO MINUTES FOR THE AIRBAG SYS-
TEM CAPACITOR TO DISCHARGE BEFORE PER-
FORMING FURTHER DIAGNOSIS OR SERVICE.
FAILURE TO TAKE THE PROPER PRECAUTIONS
COULD RESULT IN ACCIDENTAL AIRBAG DEPLOY-
MENT AND POSSIBLE PERSONAL INJURY.
(1) Remove the passenger side rear trim panel
(Refer to 23 - BODY/INTERIOR/QUARTER PANEL
TRIM - REMOVAL).
(2) Drain to cooling systems (Refer to 7 - COOL-
ING - STANDARD PROCEDURE) or (Refer to 7 -
COOLING - STANDARD PROCEDURE).
(3) Remove the three blend door actuator screws.
(4) Remove the blend door actuator and place
aside.
(5) Remove the two screws from the heater/evapo-
rator tubes plastic retainer.
(6) Using spring clamp type pliers remove the
clamps from the heater hoses,
(7) Using a twisting motion remove the heater
hoses from the heater core.
(8) Lift the heater core out of the heater-A/C hous-
ing.

INSTALLATION

(1) Insert the heater core into the bottom of the
heater-A/C housing.
(2) Using a twisting motion install the heater
hoses to the heater core.
(3) Using spring clamp type pliers install the
clamps to the heater hoses.
(4) Install the two screws to the heater/evaporator
tubes plastic retainer.
(5) Install blend door actuator.
(6) Install the three blend door actuator screws.
(7) Refill the cooling system (Refer to 7 - COOL-
ING - STANDARD PROCEDURE) or (Refer to 7 -
COOLING - STANDARD PROCEDURE).
(8) Install the passenger side rear trim panel
(Refer to 23 - BODY/INTERIOR/QUARTER PANEL
TRIM - INSTALLATION).
LIQUID LINE
REMOVAL
Any kinks or sharp bends in the refrigerant plumb-
ing will reduce the capacity of the entire air condi-
tioning system. Kinks and sharp bends reduce the
flow of refrigerant in the system. High pressures are
produced in the refrigerant system when the air con-
ditioning compressor is operating. Extreme care must
be exercised to make sure that each of the refriger-
ant system connections is pressure-tight and leak
free.
WARNING: (Refer to 24 - HEATING & AIR CONDI-
TIONING/PLUMBING - WARNING) AND (Refer to 24 -
HEATING & AIR CONDITIONING/PLUMBING - CAU-
TION) BEFORE PERFORMING THE FOLLOWING
OPERATION.
(1) Disconnect and isolate the battery negative
cable.
(2) Recover the refrigerant from the refrigerant
system (Refer to 24 - HEATING & AIR CONDITION-
ING/PLUMBING/REFRIGERANT
PROCEDURE).
(3) Remove the engine air filter housing (Refer to 9
- ENGINE/AIR INTAKE SYSTEM/AIR CLEANER
ELEMENT - REMOVAL).
(4) If the vehicle is so equipped, remove the nuts
that secure the vehicle speed control servo mounting
bracket to the studs on the cowl plenum panel and
move the servo far enough to access the liquid line to
evaporator coupler (Refer to 8 - ELECTRICAL/
SPEED CONTROL/SERVO - REMOVAL).
(5) Disconnect the liquid line fastener at the con-
denser, and refrigerant line coupler at the evaporator
(Refer to 24 - HEATING & AIR CONDITIONING/
PLUMBING - REMOVAL).
(6) Disengage the two clips that secure the liquid
line to the inner fender shield.
(7) Remove the liquid line from the vehicle.
INSTALLATION
High pressures are produced in the refrigerant sys-
tem when the air conditioning compressor is operat-
ing. Extreme care must be exercised to make sure
that each of the refrigerant system connections is
pressure-tight and leak free.
