2000 DODGE NEON air conditioning

(10) Radiator can now be lifted free from engine
compartment.Care should be taken not to dam-
age radiator cooling fins or water tubes during
removal.
INSTALLATION
(1) Slide radiator down into position behind radia-
tor support (yoke).
(2) Attach air conditioning condenser to radiator, if
equipped (Fig. 25), with four mounting screws.
Tighten screws to 5.4 N´m (50 in. lbs.). Then seat the
radiator assembly lower rubber isolators into the
mounting holes provided in the lower crossmember.
(3) Install and tighten radiator isolator mounting
bracket screws to 10 N´m (90 in. lbs.) (Fig. 24). The
radiator should have clearance to move up, approxi-
mately 5±8 mm (0.20±0.31 in.) after assembled.
(4) Install lower radiator hose. Align the hose and
position the clamp so it will not interfere with engine
components.
(5) Connect automatic transmission hoses, if
equipped. Tighten hose clamps to 2 N´m (18 in. lbs.).
(6) Slide fan module down into clip(s) on lower
radiator flange (Fig. 23). Install retaining screws and
tighten to 7.5 N´m (65 in. lbs.).
(7) Connect the cooling fan motor electrical connec-
tor.
(8) Install upper radiator hose. Align the hose and
position the clamp so they will not interfere with the
engine or the hood.
(9) Connect negative cable to battery.
(10) Fill cooling system with coolant. Refer to pro-
cedure in this section.
(11) Operate engine until it reaches normal operat-
ing temperature. Check cooling system and auto-
matic transmission for correct fluid levels.
RADIATOR DRAINCOCK
REMOVAL
(1) Turn the drain cock stem counterclockwise to
unscrew the stem. When the stem is unscrewed to
the end of the threads, pull the stem (Fig. 26) from
the radiator tank.
INSTALLATION
(1) Push the draincock assembly body into the
tank opening.
(2) Tighten the draincock stem by turning clock-
wise to 2.0-2.7 N´m (18-25 in. lbs.).
COOLING FAN MODULE
All models use a single speed electric motor driven
cooling system fan. The fan module includes a motor,
fan blade, and support shroud. The module is fas-
tened to the radiator by screws.
REMOVAL
WARNING: DO NOT REMOVE THE CYLINDER
BLOCK PLUG OR THE RADIATOR DRAINCOCK
WITH THE SYSTEM HOT AND UNDER PRESSURE
BECAUSE SERIOUS BURNS FROM COOLANT CAN
OCCUR.
(1) Disconnect negative cable from battery.
(2) Drain cooling system below upper radiator hose
level. Refer to procedure in this section.
(3) Remove upper radiator hose from radiator (Fig.
27).
(4) Disconnect fan module electrical connector.
(5) Remove fan module screws from radiator (Fig.
28).
(6) Lift fan shroud up and out of lower shroud
attachment clips.
(7) Refer to Disassembly and Assembly in this sec-
tion for fan module sub-component service proce-
dures.

(2) Connect recovery hose to water outlet connec-
tor/thermostat housing (Fig. 29).
(3) Fill container to proper level. Refer to Cooling
System Refilling in this section.
ENGINE BLOCK HEATER
REMOVAL
(1) Drain coolant from radiator and cylinder block.
Refer to Cooling System Draining in this section for
procedure.
(2) Detach power cord plug from heater (Fig. 31).
(3) Loosen screw in center of heater. Remove
heater assembly (Fig. 31).
INSTALLATION
(1) Thoroughly clean core hole and heater seat.
(2) Insert heater assembly with element loop posi-
tionedupward (Fig. 31).
(3) With heater seated, tighten center screw
securely to assure a positive seal.
(4) Connect power cord to block heater (Fig. 31).
(5) Fill cooling system with coolant to the proper
level, vent air, and inspect for leaks.
ACCESSORY DRIVE BELTS
POWER STEERING PUMP AND AIR CONDITIONING
COMPRESSOR BELT
REMOVAL
(1) Using a 17 mm wrench, rotate belt tensioner
clockwise (Fig. 33) until belt can be removed from
power steering pump pulley. Gently, release spring
tension on tensioner.
(2) Remove belt (Fig. 34).
INSTALLATION
(1) Install belt (Fig. 34) over all pulleys except for
the power steering pump pulley.
(2) Using a 17 mm wrench, rotate belt tensioner
clockwise (Fig. 33) until belt can be installed onto
power steering pulley. Release spring tension onto
belt.
NOTE: When installing drive belt onto pulleys,
make sure that belt is properly routed and all
V-grooves make proper contact with pulley grooves.
(3) After belt is installed, inspect belt length indi-
cator marks (Fig. 35). The indicator mark should be
within the minimum belt length and maximum belt
length marks. On a new belt, the indicator mark
should align approximately with the nominal belt
length mark.

REMOVAL AND INSTALLATION (Continued)

GENERATOR BELT
REMOVAL
(1) Remove power steering pump/air conditioning
compressor drive belt.
(2) Loosen pivot bolt, then locking nut and adjust-
ing bolt (Fig. 36).
(3) Remove generator belt.
NOTE: When installing drive belt onto pulleys,
make sure that belt is properly routed and all
V-grooves make proper contact with pulley grooves.
INSTALLATION
(1) Install belt and/or adjust belt tension by tight-
ening adjusting bolt. Adjust belt to specification
shown in Belt Tension Chart.
NOTE: Due to space limitations, the use of a belt
tension gauge is limited. Therefore, measure the
belt deflection at the center span of the generator
belt. Refer to Belt Tension Chart for specifications.
(2) Tighten pivot bolt to 54 N´m (40 ft. lbs.) and
locking nut to 54 N´m (40 ft. lbs.) (Fig. 36).
