Be careful not to drop mounting bolt inside timing chain
case.
b. Loosen upper mounting bolt (2) slowly, and then turn chain ten-
sioner (primary) (3) on the mounting bolt so that plunger (4) is
fully expanded.
NOTE:
Even if plunger is fully expanded, it is not dropped from the body
of timing chain tensioner (primary).
c. Turn crankshaft pulley clockwise so that timing chain on the tim-
ing chain tensioner (primary) side is loose.
d. Remove upper mounting bolt, and then remove timing chain ten-
sioner (primary).
CAUTION:
Be careful not to drop mounting bolt inside timing chain
case.
12. 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.

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.

WATER PUMP
 Check for rough operation due to excessive end play.
 If anything is found, replace water pump.
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.
