7. Remove timing chain tensioner (primary) as follows:
a. Pull lever down and release plunger stopper tab.

Plunger stopper tab can be pushed up to release (coaxial
structure with lever).
b. Insert a stopper pin into tensioner body hole to hold lever, and keep tab released.
NOTE:
An allen wrench [2.5 mm (0.098 in)] is used for the stopper pin
as an example.
c. Insert plunger into tensioner body by pressing slack guide.
d. Keep slack guide pressed and hold plunger in by pushing stop- per pin through the lever hole and tensioner body hole.
e. Turn crankshaft pulley clockwise so that timing chain on the tim- ing chain tensioner (primary) side is loose.
f. Remove mounting bolts and remove timing chain tensioner (pri- mary).
CAUTION:
Be careful not to drop mounting bolts inside timing chain
case.
8. Remove water pump as follows:
a. Remove three water pump mounting bolts. Secure a gap between water pump gear and timing chain, by turning crank-
shaft pulley counterclockwise until timing chain looseness on
water pump sprocket becomes maximum.

INSTALLATION
Note the following, and install in the reverse order of removal.

Securely insert each hose, and install clamp at a position where it does not interfere with the pipe bulge.

When inserting water pipe into water outlet, apply neutral detergent to O-ring.
INSPECTION AFTER INSTALLATION

Check for leaks of engine coolant using the radiator cap tester adapter [SST: EG17650301 (J33984-A)]
and the radiator cap tester (commercial service tool). Refer to CO-11, "
LEAK CHECK" .

Start and warm up the engine. Visually make sure that there is no leaks of engine coolant.

4. Make sure that the rim is completely crimped down.
5. Make sure that there is no leakage.Refer to CO-48, "
INSPECTION" .
INSPECTION
1. Apply pressure with radiator cap tester adapter (SST) and radia-
tor cap tester (commercial service tool).

provide used radiator and connect it to tested radiator using
radiator hoses as shown in the figure.
NOTE:
The used radiator should be tested beforehand to confirm it
has no leakage. If used one is not available, it is possible to
use new service part as a radiator testing tool.
WARNING:
To prevent the risk of hose coming undone while under pressure, securely fasten it down with
hose clamp.
CAUTION:
Attach hose to A/T fluid cooler to seal its inlet and outlet.
2. Check for leakage by soaking radiator in water container with the testing pressure applied. Standard height “H” : 8.0 - 8.4 mm (0.315 - 0.331 in)

Removal and InstallationABS006JO
CAUTION:

When removing water pump, be careful not to get engine coolant on drive belts.

Water pump can not be disassembled and should be replaced as a unit.

After installing water pump, connect hose and clamp securely, then check for leaks using radiator
cap tester (commercial service tool) and radiator cap tester adapter [SST: EG17650301 (J33984-
A)].
REMOVAL
1. Drain engine coolant from drain plugs on radiator and both side of cylinder block. Refer to CO-37, "Chang-
ing Engine Coolant" and EM-246, "DISASSEMBLY" .
CAUTION:

Perform this step when engine is cold.

Do not spill engine coolant on drive belts.
2. Remove following parts:

Engine front undercover

Air duct (inlet); Refer to EM-176, "AIR CLEANER AND AIR DUCT" .

Alternator, water pump and A/C compressor belt; Refer to EM-173, "DRIVE BELTS" .
3. Remove fan coupling with cooling fan, and then water pump pulley.
4. Remove water pump.

Engine coolant will leak from cylinder block, so have a receptacle ready under vehicle.
CAUTION:

Handle the water pump vane so that it does not contact any other parts.

Do not disassemble water pump.

THERMOSTAT AND WATER CONTROL VALVE
Revision: 2005 July 2005 FX
7. Disconnect radiator hose (upper) and water hoses from thermostat housing.
8. Disconnect heater hoses from water outlet and heater pipe.
9. Remove thermostat housing, water outlet pipe, water connector, water control valve, water outlet and heater pipe.
CAUTION:
Do not disassemble water control valve.
INSPECTION AFTER REMOVAL

Make sure that valves both in thermostat and water control valve are completely closing at normal tempar-
ature.

Place a thread so that it is caught in the valves of the thermostat
and water control valve. Immerse fully in a container filled with
water. Heat while stirring. (The example in the figure shows ther-
mostat.)

The valve opening temperature is the temperature at which the
valve opens and falls from the thread.

Continue heating. Check the maximum valve lift.
NOTE:
The maximum valve lift standard temperature for water control
valve is the reference value.

After checking the maximum valve lift, lower the water tempera-
ture and check the valve closing temperature.
Standard values:

If the malfunctioning condition, when closing valve at normal temperature, or measured values are out of
the standard, replace thermostat and/or water control valve.
INSTALLATION
Note the following, and install in the reverse order of removal.
CAUTION:
Be careful not to spill engine coolant over engine room. Use rag to absorb engine coolant.
Thermostat and Water Control Valve

Install thermostat and water control valve with the whole circum-
ference of each flange part fit securely inside rubber ring. (The
example in the figure shows thermostat.)
