5. Make sure that there is no leakage.
Refer to "INSPECTION".
INSPECTION
1. Apply pressure with the radiator cap tester adapter (commercial
service tool) (A) and the radiator cap tester (commercial service
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.Testing pressure

CAUTION:
 Perform this step when the engine is cold.
 Do not spill engine coolant on drive belts.
4. Remove air duct (inlet), power duct and air cleaner case assembly. Refer to EM-17, "
Component".
5. Remove water drain plug (front) on water pump side of cylinder block to drain engine coolant from engine inside.
6. Remove chain tensioner cover and water pump cover from front timing chain case.  Use the seal cutter [SST: KV10111100 (J37228)] to cut liquid gasket for removal.
7. Remove timing chain tensioner (primary) as follows:

a. Remove lower mounting bolt.
CAUTION:
Be careful not to drop mounting bolt inside timing chain
case.
b. Loosen upper mounting bolt slowly, and then turn chain ten- sioner (primary) on the mounting bolt so that plunger 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.
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.

a. Turn crankshaft pulley clockwise so that timing chain on the tim-
ing chain tensioner (primary) side is loose.
b. 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.
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 through hole of lever into ten- sioner body hole.
 The lever parts and the tab are synchronized. Therefore, theplunger will be secured under this condition.
NOTE:
Figure shows the example of 1.2 mm (0.047 in) diam eter 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.
h. 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 a scraper. Also remove traces of old liquid gasket from the
mating surface of front timing chain case.

WATER OUTLET AND WATER PIPING
Note the following, and install in the reverse order of removal.
 Securely insert each hose, and install clamp at a pos
ition 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 (commercial service tool) and the
radiator cap tester (commercial service tool). Refer to CO-10, "
Inspection".
 Start and warm up the engine. Visually make sure that there is no leaks of engine coolant.

INSPECTION
1. Apply pressure with radiator cap tester adapter (commercial ser-
vice tool) and radiator cap tester (commercial service tool).
 provide used radiator and connect it to tested radiator usingradiator 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 whil e under pressure, securely fasten it down with
hose clamp.
CAUTION:
Attach hose to A/T fluid cooler to seal its inlet and outlet.
