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

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
