3. Remove reservoir tank as necessary, and drain engine coolant and clean reservoir tank before installing.
4. Check drained engine coolant for contaminants such as rust, corrosion or discoloration.
If contaminated, flush the engine cooling sys tem. Refer to "FLUSHING COOLING SYSTEM".
REFILLING ENGINE COOLANT
1. Install reservoir tank if removed, and radiator drain plug.
CAUTION:
Be sure to clean drain plug and install with new O-ring.
If water drain plugs on cylinder block are removed, close and tighten them. Refer to EM-123, "
Dis-
assembly and Assembly".
2. Make sure that each hose clamp has been firmly tightened.
3. Remove air relief plug on heater hose.
4. Fill radiator, and reservoir tank if removed, to specified level. Pour engine coolant through engine coolant filler neck
slowly of less than 2 (2-1/8 US qt, 1-3/4 lmp qt) a minute
to allow air in system to escape.
 Use Genuine NISSAN Long Li fe Antifreeze/Coolant or
equivalent mixed with water (dis tilled or demineralized).
Refer to MA-9, "
Fluids and Lubricants".
 When engine coolant overflows air relief hole on heater hose, install air relief plug with new O-ring.
5. Install radiator cap.
6. Warm up until opening thermostat. Standard for warm ing-up time is approximately 10 minutes at 3,000
rpm.
 Make sure thermostat opening condition by touching r adiator hose (lower) to see a flow of warm water.
CAUTION:
Watch water temperature gauge so as not to overheat engine.
7. Stop the engine and cool down to less than approximately 50 °C (122 °F).

ENGINE COOLANT
 Cool down using fan to reduce the time.
 If necessary, refill radiator up to filler neck with engine coolant.
8. Refill reservoir tank to “MAX” level line with engine coolant.
9. Repeat steps 4 through 7 two or more times with radiator cap installed until engine coolant level no longer drops.
10. Check cooling system for leaks with engine running.
11. Warm up the engine, and check for sound of engine coolant flow while running engine from idle up to 3,000 rpm with heater temperature controller set at several position between “COOL” and “WARM”.
 Sound may be noticeable at heater unit.
12. Repeat step 11 three times.
13. If sound is heard, bleed air from cooling system by repeating step 4 through 7 until engine coolant level no
longer drops.
FLUSHING COOLING SYSTEM
1. Install reservoir tank if removed, and radiator drain plug.
If water drain plugs on cylinder block are removed, close and tighten them. Refer to EM-123, "
Dis-
assembly and Assembly".
2. Remove air relief plug on heater hose.
3. Fill radiator with water until water spills from the ai r relief hole, then close air relief plug. Fill radiator and
reservoir tank with water and reinstall radiator cap.
4. Run the engine and warm it up to normal operating temperature.
5. Rev the engine two or three times under no-load.
6. Stop the engine and wait until it cools down.
7. Drain water from the system. Refer to "DRAINING ENGINE COOLANT".

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.

b. Apply a continuous bead of liquid gasket with the tube presser
(commercial service tool) to mating surface of chain tensioner
cover and water pump cover.
Use Genuine RTV Silicone Seal ant or equivalent. Refer to
GI-44, "
Recommended Chemical Product and Sealant".
CAUTION:
Attaching should be done with in 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 RTV Silicone Sealant or equivalent. Refer to GI-44, "
Recommended Chemical Prod-
uct and Sealant".
6. Install in the reverse order of removal for remaining parts. After starting engine, let idle fo r three minutes, then rev engine up to 3,000 rpm under no load to
purge air from the high-pressure chamber of ch ain tensioner. Engine may produce a rattling
noise. This indicates that air still remains in the chamber and is not a matter of concern.
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.
