LEVEL
 Check if the reservoir tank engine coolant level is within the “MIN”
to “MAX” when the engine is cool.
 Adjust the engine coolant level as necessary.
LEAKAGE
 To check for leakage, apply pressure to the cooling system with the
radiator cap tester (commercial service tool) (A) and radiator cap
tester adapter (commercial service tool) (B).
WARNING:
Never remove radiator cap when engine is hot. Serious burns
could occur from high-pressure engine coolant escaping from
radiator.
CAUTION:
Higher test pressure than specified may cause radiator dam-
age.
NOTE:
In a case that engine coolant decreases, replenish radiator with engine coolant.
 If anything is found, repair or replace damaged parts.
DrainingINFOID:0000000003793167
WARNING:
 To avoid being scalded, never change engine coolant when the engine is hot.
 Wrap a thick cloth around radiator cap and carefully remove radiator cap. First, turn radiator cap a
quarter of a turn to release built-up pressure. Then turn radiator cap all the way.
1. Remove engine under cover.
2. Open radiator drain plug (1) at the bottom of radiator, and then
remove radiator cap.
When draining all of engine coolant in the system, open water drain plugs on cylinder block. Refer
to EM-110, "
Disassembly and Assembly".
3. Remove reservoir tank as necessary, and drain engine coolant and clean reservoir tank before installing.

4. Disconnect heater hose (1) at the position ( ) in the figure.
5. Fill radiator, and reservoir tank if removed, to specified level.
CAUTION:
Never adhere the engine coolant to electronic equipments.
(alternator etc.)
Pour engine coolant through engine coolant filler neck
slowly of less than 2 (1-3/4 lmp qt) a minute to allow air
in system to escape.
When engine coolant overflows disconnected heater
hose, connect heater hose, and continue filling the engine
coolant.
Use Genuine NISSAN Engine Coolant or equivalent in its
quality mixed with water (distilled or demineralized). Refer
to MA-11, "
Fluids and Lubricants". Tightening torque : Refer to CO-13, "

8. Warm up engine until opening thermostat. Standard for warming-up time is approximately 10 minutes at
3,000 rpm.
 Check thermostat opening condition by touching radiator hose (lower) to see a flow of warm water.
CAUTION:
Watch water temperature gauge so as not to overheat engine.
9. Stop the engine and cool down to less than approximately 50°C (122°F).
 Cool down using fan to reduce the time.
 If necessary, refill radiator up to filler neck with engine coolant.
CAUTION:
Never adhere the engine coolant to electronic equipments. (alternator etc.)
10. Refill reservoir tank to “MAX” level line with engine coolant.
11. Repeat steps 7 through 10 two or more times with radiator cap installed until engine coolant level no
longer drops.
12. Check cooling system for leakage with engine running.
13. 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.
14. Repeat step 13 three times.
15. If sound is heard, bleed air from cooling system by repeating step 5, and steps from 7 to 14 until engine
coolant level no longer drops.

plunger stopper tab with the tip of ratchet.
e. To secure lever, insert stopper pin (E) through hole of lever into
tensioner body hole (B).
 The lever parts and the tab are synchronized. Therefore, the
plunger will be secured under this condition.
NOTE:

g. Remove stopper pin (A).
h. Check again that timing chain and water pump sprocket are engaged.
4. Install valve timing control cover (bank 1) and water pump cover as follows:
a. Before installing, remove all traces of old liquid gasket from mating surface of water pump 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 the tube presser
(commercial service tool) to mating surface of water pump cover
(1).
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 after this step.
After starting engine, let idle for three minutes, then rev engine up to 3,000 rpm under no load to
purge air from the high-pressure chamber of chain tensioner. Engine may produce a rattling
noise. This indicates that air still remains in the chamber and is not a matter of concern.
