WATER PUMP
b. Screw M8 bolts [pitch: 1.25 mm (0.0492 in) length: approxi-
mately 50 mm (1.97 in)] into water pumps upper and lower
mounting bolt holes until they reach timing chain case. Then,
alternately tighten each bolt for a half turn, and pull out water
pump.
CAUTION:
 Pull straight out while preventing vane from contacting
socket in installation area.
 Remove water pump without causing sprocket to contact
timing chain.
c. Remove M8 bolts and O-rings from water pump.
CAUTION:
Never disassemble water pump.
INSTALLATION
1. Install new O-rings to water pump.
 Apply engine oil and engine coolant to O-rings as shown in the
figure.
 Locate O-ring with white paint mark to engine front side.
2. Install water pump.
CAUTION:
Never allow cylinder block to nip O-rings when installing
water pump.
 Check that timing chain and water pump sprocket are
engaged.
 Insert water pump by tightening mounting bolts alternately and
evenly.
3. Install timing chain tensioner (primary) as follows:
a. Turn crankshaft pulley clockwise so that timing chain on the tim-
ing chain tensioner (primary) side is loose.

b. Pull plunger stopper tab (A) up (or turn lever downward) so as to
remove plunger stopper tab from the ratchet of plunger (D).
NOTE:
Plunger stopper tab and lever (C) are synchronized.
c. Push plunger into the inside of tensioner body.
d. Hold plunger in the fully compressed position by engaging
plunger stopper tab with the tip of ratchet.
e. To secure lever, insert stopper pin (E) through hole of lever into
tensioner body hole (B).
 The lever parts and the tab are synchronized. Therefore, the
plunger will be secured under this condition.
NOTE:
Figure shows the example of 1.2 mm (0.047 in) diameter thin screwdriver being used as the stopper pin.
f. Install timing chain tensioner (primary).
 Remove dust and foreign material completely from backside of timing chain tensioner (primary) and
from installation area of rear timing chain case.
g. Remove stopper pin (A).
h. Check again that timing chain and water pump sprocket are engaged.
4. Install valve timing control cover (bank 1) and water pump cover as follows:
a. Before installing, remove all traces of old liquid gasket from mating surface of water pump cover using
scraper. Also remove traces of old liquid gasket from the mating surface of front timing chain case.
b. Apply a continuous bead of liquid gasket with the tube presser
(commercial service tool) to mating surface of water pump cover
(1).
Use Genuine Liquid Gasket or equivalent.
CAUTION:
Attaching should be done within 5 minutes after coating.
c. Tighten mounting bolts.
5. Install water drain plug (front) on water pump side of cylinder block.
 Apply liquid gasket to the thread of water drain plug (front).
Use Genuine Liquid Gasket or equivalent.
6. Install in the reverse order of removal after this step.
After starting engine, let idle for three minutes, then rev engine up to 3,000 rpm under no load to
purge air from the high-pressure chamber of chain tensioner. Engine may produce a rattling
noise. This indicates that air still remains in the chamber and is not a matter of concern.

InspectionINFOID:0000000003793187
INSPECTION AFTER INSTALLATION
 Check for leakage of engine coolant using the radiator cap tester adapter (commercial service tool) and the
radiator cap tester (commercial service tool). Refer to CO-8, "
Inspection".
 Start and warm up the engine. Visually check that there is no leakage of engine coolant.
