WATER PUMP


Check for rough operation due to excessive end play.

Replace water pump, if necessary.
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:
Do not allow timing chain case to nip O-rings when install-
ing water pump.

Make sure that timing chain and water pump sprocket are
engaged.

Insert water pump by tightening mounting bolts alternately
and evenly.
3. Install the timing chain tensioner (primary) with the following procedure:
a. Pull plunger stopper tab up (or turn lever downward) so as to
remove plunger stopper tab from the ratchet of plunger.
NOTE:
Plunger stopper tab and lever are synchronized.
b. Push plunger into the inside of tensioner body.
c. Hold plunger in the fully compressed position by engaging
plunger stopper tab with the tip of ratchet.
d. To secure lever, insert stopper pin through hole of lever into ten-
sioner body hole.

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.

e. Install timing chain tensioner (primary).

Remove any dirt and foreign materials completely from the
back and the mounting surfaces of timing chain tensioner (pri-
mary).
f. Pull out stopper pin after installing, and then release plunger.
g. Make sure again that timing chain and water pump sprocket are
engaged.
4. Install chain tensioner cover and water pump cover as follows:
a. Before installing, remove all traces of old liquid gasket from mat-
ing surface of water pump cover and chain tensioner 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 tube presser [SST:
WS39930000] to mating surface of chain tensioner cover and
water pump cover.
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 in this step.
NOTE:
If hydraulic pressure inside timing chain tensioner drops after removal/installation, slack in guide may gen-
erate a pounding noise during and just after engine start. However, this does not indicate an unusualness.
Noise will stop after hydraulic pressure rises.
INSPECTION AFTER INSTALLATION

Check for leaks of engine coolant using radiator cap tester adapter [SST: EG17650301] and radiator cap
tester (commercial service tool). Refer to CO-34, "
LEAK CHECK" .

Start and warm up engine. Visually check if there is no leaks of engine coolant.
