ELECTRIC COOLANT PUMP
DESCRIPTION
The electric coolant pump is used on all vehicles.
The pump is located in the left side of the engine
compartment near the battery.
OPERATION
The pump is controlled by the ATC control module
and is only operational under the following condi-
tions:
(1) Vehicle speed below 27 Km/h (17 mph).
(2) Coolant temperature above 65É C (150É F) but
less than 110É C (230 É F).
(3) Any blower speed setting.
(4) Temperature heat setting above the halfway
setting (60% heat).
(5) The pump will turn off at speeds above 48
Km/h (30 mph).
(6) The pump will turn off if the coolant tempera-
ture rises above 110É C (230 É F).
REMOVAL
(1) Disconnect and isolate the battery negative
cable.
(2) Partially drain the engine cooling system
(Refer to 7 - COOLING/ENGINE/COOLANT - STAN-
DARD PROCEDURE).
(3) Disconnect the wire harness connector from the
electric coolant pump (Fig. 7).
(4) Loosen both hose clamps from the electric cool-
ant pump.
(5) Using a twisting motion gently remove both
heater hoses from the electric coolant pump.
(6) Remove the two electric coolant pump bracket
retaining nuts from the body studs.
(7) Remove the electric coolant pump from the
vehicle.
INSTALLATION
(1) Install the electric coolant pump and mounting
bracket onto the body studs.(2) Install the two bracket retaining nuts. Tighten
the nuts to 5 N´m (45 in. lbs.).
(3) Using a twisting motion gently install both
hoses onto the electric coolant pump.
(4) Tighten both hose clamps securely.
(5) Connect the wire harness connector to the elec-
tric coolant pump.
(6) Reconnect the battery negative cable.
(7) Fill the cooling system (Refer to 7 - COOLING/
ENGINE/COOLANT - STANDARD PROCEDURE).
HEATER CORE
DESCRIPTION
The heater core is located in the heater housing,
behind the instrument panel. It is a heat exchanger
made of rows of tubes and fins.
OPERATION
Engine coolant is circulated through the heater
hoses to the heater core whenever the heater water
valve is cycled open by the ATC control module. As
the coolant flows through the heater core, heat
removed from the engine is transferred to the heater
core fins and tubes. Air directed through the heater
core picks up the heat from the heater core fins. The
heater water valve controls the heater output air
temperature by controlling the amount of heated
engine coolant flowing through the heater core. The

blower motor speed controls the volume of air flowing
through the heater housing.
The heater core cannot be repaired and, if faulty or
damaged, it must be replaced.

RECEIVER/DRIER
DESCRIPTION
The receiver/drier is mounted in a bracket secured
to the left front strut tower in the engine compart-
ment. The receiver/drier is connected between the
front and rear sections of the liquid line between the
condenser outlet and the evaporator inlet. The receiv-
er/drier cannot be repaired. If the receiver/drier is
faulty or damaged, or if the refrigerant system has
been contaminated or left open to the atmosphere for
an indeterminable period or if the compressor has
failed, it must be replaced.
OPERATION
The receiver/drier performs a filtering action to
prevent foreign material in the refrigerant from con-
taminating the expansion valve. A desiccant bag is
mounted inside the receiver/drier canister to absorb
any moisture which may have entered and become
trapped within the refrigerant system. In addition,
during periods of high demand air conditioner opera-
tion, the receiver/drier acts as a reservoir to store
surplus refrigerant. Refrigerant enters the receiver/
drier as a high-pressure, low-temperature liquid.

TIONS IN THE FRONT OF THIS SECTION BEFORE
