CAUTION: After removing fan clutch assembly, DO NOT store fan clutch
with rear of shaft pointing downward. Silicone fluid from fan
clutch may drain into fan drive bearing, causing lubricant
failure.
Removal
1) Disconnect negative battery cable. Drain cooling system.
Remove throttle cable at top of fan shroud. Unsnap coolant overflow
tank from fan shroud and lay aside. DO NOT disconnect coolant hose.
2) Remove upper radiator hose. Using Fan Wrench (SP346) from\
Set (2017DSP), remove fan clutch assembly from water pump by turning
nut counterclockwise as viewed from front. DO NOT remove fan clutch
assembly at this time.
3) Remove fan shroud bolts and clips. Remove fan shroud and
fan clutch assembly as a unit. Locate accessory drive belt tensioner,
and rotate tensioner clockwise (counterclockwise on heavy-duty cycle
engines) to release tension on accessory drive belt.
4) Note drive belt routing for installation reference. Belt
must be correctly routed during installation, or engine will overheat
due to water pump rotating in wrong direction.
5) Remove bolts and water pump pulley. Disconnect lower
radiator hose and heater hoses. Remove coolant return tube from water
pump. Remove bolts, water pump and gasket.
Installation
To install, reverse removal procedure using NEW gasket.
Tighten bolts to specification. See TORQUE SPECIFICATIONS table. Fill
system with coolant. Ensure accessory drive belt is installed in
original direction to ensure proper rotation of water pump. See
Fig. 12 .

1999 HEATER SYSTEMS
RWD Trucks & Vans
CHRYSLER
Dakota, Durango, Ram Pickup, Ram Van/Wagon
DESCRIPTION
All models use a blend-air system. Outside air enters heater
through cowl opening and passes through a plenum chamber to heater
core. Blend air door in heater housing controls temperature by either
directing air through or around heater core. Air flow is then directed
through dash panel to air distribution duct in passenger compartment.
On Durango, air taken from the front heater system is fed
back through an air duct into the center console. At the rear of the
center console, passengers can operate a 3 mode switch to adjust air
flow. Temperature and blower speeds are controlled by the front heater
control panel.
WARNING: To avoid injury from accidental air bag deployment, read and
carefully follow all SERVICE PRECAUTIONS and DISABLING &
ACTIVATING AIR BAG SYSTEM procedures in AIR BAG SYSTEM SAFETY
article.
OPERATION
HEATER CONTROL PANEL
Blower Motor Switch
Fan speed is controlled with a rotary blower motor switch.
There are 4 different fan speed settings: one low speed, 2 medium
speeds, and one high speed.
Mode Control Knob
A rotary mode switch is used to control air flow. There are 5
different modes of operation: panel, floor/panel, floor,
floor/defrost, and defrost.
Temperature Control Knob
Rotary control knob determines discharge air temperature by
positioning blend/air door. On Dakota and Durango, temperature blend-
air door is cable operated. On Ram Pickup and Ram Van/Wagon,
temperature blend-air door is electrically operated. When a hot
temperature is selected, all air flows through heater core.
ADJUSTMENTS
TEMPERATURE CONTROL CABLE ADJUSTMENT
Dakota & Durango
1) Ensure temperature control cable housing and core are
connected at both heater control panel and heater assembly. Ensure
heater control panel is properly installed.
2) Rotate temperature control knob so that knob pointer is at
12 o'clock position. Pull temperature control knob straight out from
heater control panel until perimeter of knob (not knob pointer)
protrudes about .25" (6 mm) from face of heater control panel.
3) Rotate temperature control knob clockwise so that knob

1998-99 WHEEL ALIGNMENT
CHRY - Specifications & Procedures - Trucks & FWD Vans
Caravan, Dakota, Durango, Ram Pickup, Ram Van/Wagon,
Town & Country, Voyager
NOTE: Prior to performing wheel alignment, perform visual and
mechanical inspection of wheels, tires and suspension
components. See PRE-ALIGNMENT INSTRUCTIONS in WHEEL ALIGNMENT
THEORY & OPERATION article in GENERAL INFORMATION.
RIDING HEIGHT ADJUSTMENT
CHECKING PROCEDURE
NOTE: Information on vehicles not listed was not available from
manufacturer.
1999 Caravan, Town & Country, & Voyager
Before adjusting alignment, check riding height. Measure
height from inboard edge of fenderwell directly above center of wheel,
unless specified otherwise. Riding height must be checked with vehicle
on level floor, correct size tires properly inflated and fuel tank
full. Bounce vehicle several times and allow suspension to settle.
Visually inspect vehicle for signs of abnormal height from
front-to-rear and side-to-side. Check passenger and luggage
compartments for extra-heavy items and remove if present. Riding
height between left side and right side of vehicle should vary less
than 0.5 (12.7 mm). Information on riding height between front and
rear is not available from manufacturer. See RIDING HEIGHT
SPECIFICATIONS (1999 CARAVAN, TOWN & COUNTRY, & VOYAGER) table. If
riding height is not within specification, check, repair or replace
suspension components.
Dakota & Durango (4WD)
1) Measure and record distance between floor surface and
center of lower suspension arm rear mounting bolt head. Measure and
record distance between floor surface and center of front wheel. See
Fig. 1 . Subtract first measurement from second measurement. On Dakota,
difference between both measurements should be 1.725-1.975" (43.82-50.
16 mm). On Durango, difference between both measurements should be 2.
78-3.02" (70.6-76.7 mm).
2) If necessary, adjust height differential to specification.
Adjust each front suspension arm by rotating torsion bar anchor
adjustment bolt clockwise to raise vehicle and counterclockwise to
lower vehicle. Always raise vehicle to correct height. If vehicle
height is greater than maximum specification, lower height to less
than specification, then back up to specification. After each
adjustment, jounce vehicle before measuring height to determine
effects of adjustment.
