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 .

GENERAL INFORMATION
General Cooling System Servicing
* PLEASE READ THIS FIRST *
The following article is for general information only.
Information may not apply to all years, makes and models. See specific
article in the ENGINE COOLING section.
DESCRIPTION
The basic liquid cooling system consists of a radiator, water
pump, thermostat, electric or belt-driven cooling fan, pressure cap,
heater, and various connecting hoses and cooling passages in the block
and cylinder head.
MAINTENANCE
DRAINING
Remove radiator cap and open heater control valve to maximum
heat position. Open drain cocks or remove plugs in bottom of radiator
and engine block. In-line engines usually have one plug or drain cock,
while "V" type engines will have 2, one in each bank of cylinders.
CLEANING
A good cleaning compound removes most rust and scale. Follow
manufacturer's instructions in the use of cleaner. If considerable
rust and scale has to be removed, cooling system should be flushed.
Clean radiator air passages with compressed air.
FLUSHING
CAUTION: Some manufacturers use an aluminum and plastic radiator.
Flushing solution must be compatible with aluminum.
Back Flushing
Back flushing is an effective means of removing cooling
system rust and scale. The radiator, engine and heater core should be
flushed separately.
Radiator
To flush radiator, connect flushing gun to water outlet of
radiator and disconnect water inlet hose. To prevent flooding engine,
use a hose connected to radiator inlet. Use air in short bursts to
prevent damage to radiator. Continue flushing until water runs clear.
Engine
To flush engine, remove thermostat and replace housing.
Connect flushing gun to water outlet of engine. Flush using short air
bursts until water runs clean.
Heater Core
Flush heater core as described for radiator. Ensure heater
control valve is set to maximum heat position before flushing heater.
