Water Pump
The centrifugal type water pump is used in the cooling system.
The pump impeller is supported by a totally sealed bearing.
The water pump can not be disassembled.
Thermostat
A wax pellet type thermostat is used in the cooling system.
The temperature at which the valve begins to open is stamped on
thermostat.
In the top portion of the thermostat, an air bleed valve (1) is pro-
vided; this valve is for venting out the gas or air, if any, that is
accumulated in the circuit.
Cooling Fan Clutch
Fluid is enclosed in the cooling fan clutch (2) and at its center
front, there is a bimetal (3) whose thermal reaction and the engine
speed control the cooling fan speed.
Coolant (Water) Temperature Gauge
A water temp. gauge is located at intake manifold.
This gauge activates a temp. meter in the instrument cluster.
When installing, wind sealing tape on gauge thread and tighten it.
NOTE:
Do not disassemble clutch assembly.
WARNING:
Keep hands, tools, and clothing away from engine cool-
ing fan (1) to help prevent personal injury.

Water Pump Belt and Cooling Fan
REMOVAL
1) Remove radiator shroud securing bolts (1).
2) Remove radiator by referring to “Radiator” in this section.
3) Loosen water pump drive belt tension.
4) Remove cooling fan by removing securing nuts.
Remove power steering and/or compressor drive belt before
removing water pump belt.
5) Remove pump belt.
INSTALLATION
Once cooling fan or water pump belt has been removed, make
sure to tighten bolts and nuts securely in reinstallation and adjust
pump belt tension to specification. For specified tension, refer to
“Water Pump Belt Tension” in this section.
WATER PUMP BELT TENSION INSPECTION
1) Check belt tension. It should be within specification. Refer to
“Water Pump Belt Tension” in this section.
2) If tension is out of specification, adjust it.
For its adjustment, refer to “Water Pump Belt Tension” in this
section.
After adjustment, be sure to tighten bolts.
COOLING FAN CLUTCH INSPECTION
Inspect fluid coupling for oil leakage.
If necessary, replace fan clutch assembly. Do not disassemble
clutch assembly.

“A” : Sealant 99000-31150
Sealant quantity for mating surface of water pump
Width “a” : 3mm (0.12 in.)
Height “b” : 2mm (0.08 in.)
2) Install water pump (1) to cylinder block.
Tightening torque
Water pump bolts (a) : 23 N·m (2.3 kg-m, 17.0 lb-ft)
3) Install water pump pulley (2) with fan clutch (3).
Tightening torque
Water pump pulley nuts (b) : 11 N·m (1.1 kg-m, 8.0 lb-ft)
Fan clutch bolts (c) : 11 N·m (1.1 kg-m, 8.0 lb-ft)
4) Install water pump drive belt, cooling fan and radiator
shroud.
5) Adjust water pump belt tension.
Refer to “Water Pump Belt Tension” in this section.
6) Connect negative cable at battery.
7) Fill the cooling system.NOTE:
Do not disassemble water pump.
If any repair is required on pump, replace it as assembly.

Air Intake System
The main components of the air intake system are air cleaner (1), air cleaner outlet hose (2), throttle body (3),
idle air control valve (4) and intake manifold (5).
The air (by the amount corresponding to the throttle valve (6) opening and engine speed) is filtered by the air
cleaner (1), passes through the throttle body (3), is distributed by the intake manifold (5) and finally drawn into
each combustion chamber.
When the idle air control valve (4) is opened according to the signal from ECM, the air (7) bypasses the throttle
valve (6) through bypass passage and is finally drawn into the intake manifold (5).
