REFILLING
To prevent air from being trapped in engine block, engine
should be running when refilling cooling system. After system is full,
continue running engine until thermostat is open, then recheck fill
level. Do not overfill system.
TESTING
THERMOSTAT
1) Visually inspect thermostat for corrosion and proper
sealing of valve and seat. If okay, suspend thermostat and thermometer
in a 50/50 mixture of coolant and water. See Fig. 1. Do not allow
thermostat or thermometer to touch bottom of container. Heat water
until thermostat just begins to open.
2) Read temperature on thermometer. This is the initial
opening temperature and should be within specification. Continue
heating water until thermostat is fully open and note temperature.
This is the fully opened temperature. If either reading is not to
specification, replace thermostat.
Fig. 1: Testing Thermostat in Anti-Freeze/Water Solution
PRESSURE TESTING
A pressure tester is used to check both radiator cap and
Page 828 of 1691
1) Connect a vacuum gauge in line with Black heater vacuum
supply hose (located at tee near power brake booster, in engine
compartment). Position gauge so it can be viewed from passenger
compartment.
2) Start engine. While observing vacuum gauge, rotate mode
control knob to each mode position (one position at a time). Pause
after each selection. Vacuum gauge should drop then return to 8 in. Hg
shortly after each selection is made. If vacuum gauge reading is as
specified, go to next step. If gauge reading is not as specified,
check for vacuum leak in vacuum lines or heater control panel.
3) Move temperature control knob quickly to full hot and full
cold positions. A distinct sound of blend-air door hitting its stops
should be heard. No spring-back of knob should exist.
4) If temperature control knob operates as specified,
temperature control system is okay. If temperature control knob does
not operate as specified, check condition, routing, installation and
adjustment of temperature control cable. See
TEMPERATURE CONTROL CABLE ADJUSTMENT.
HEATER OUTPUT
1) Start engine. Allow engine to reach normal operating
temperature. With engine at idle, set controls to maximum heat, floor
and high blower positions. Using a thermometer, check air temperature
coming from floor vents. See HEATER OUTPUT TEMPERATURE table.
2) If floor outlet air temperature is lower than specified,
check cooling system and electric cooling fan. See ELECTRIC COOLING
FAN article.
3) Check that both return and supply heater hoses are hot. If
coolant return hose is much cooler than supply hose, repair coolant
obstruction in heater system. Check for air flow obstruction in heater
system. Check blend air door for proper operation.

cover facing down. Remove 2 bolts securing heater assembly housing
cover to blower motor housing cover. Unplug vacuum harness connector
from panel/defrost door actuator.
5) Remove floor duct from heater assembly housing. Remove 2
bolts securing heater assembly housing cover to lower housing near
floor outlet. Turn assembly over. Disengage vacuum harness retainer
and vacuum harness. Remove 13 screws securing housing cover.
6) Remove blend-air door lever. Gently pry panel-defrost door
lever off. Pull up on heater assembly housing cover far enough to
separate cover sealant and remove cover.
Installation
Ensure blower motor housing cover sealant is in place and in
good condition. To complete installation, reverse removal procedure.
Removal (Ram Pickup)
1) Disconnect negative battery cable. Drain cooling system.
In engine compartment, remove coolant hoses from heater core tubes.
Plug all openings. Remove coolant overflow bottle. Remove instrument
panel. See INSTRUMENT PANEL . Remove Powertrain Control Module (PCM)
and position aside. DO NOT disconnect 60-pin connector from PCM.
2) Remove attaching nuts from studs on engine compartment
side of dash panel. Remove defrost duct. Disconnect electrical
connectors. Remove attaching nuts from studs in passenger compartment
side of dash panel. Remove heater assembly from vehicle.
3) Place heater assembly upside-down on work bench. Remove
screw securing floor duct to bottom of heater assembly and slide floor
duct off of center heat duct adapter. Unsnap center heat duct adapter
from bottom of heater assembly housing. Remove screw hidden behind
adapter. Remove remaining screws and separate heater assembly.
Installation
Ensure mode door pivot pins are properly inserted in holes.
To complete installation, reverse removal procedure.
Removal & Installation (Ram Van/Wagon)
1) Disconnect negative battery cable. Drain engine cooling
system. In engine compartment, protect generator from coolant
spillage. Remove heater hoses from heater core tubes. Plug all
openings. Remove grille, cowl grille support panel, right headlight
assembly, and right radiator core support assembly. See Fig. 7.
2) From inside vehicle, remove glove box bin. Through glove
box opening and from under instrument panel, remove nuts and bolts
