DRIVE BELT : CheckingINFOID:0000000003862447
WARNING:
Be sure to perform the this step when engine is stopped.
 Check that the indicator (A) of drive belt auto-tensioner is within the possible use range (C).
NOTE:
 Check the drive belt auto-tensioner indication when the engine is cold.
 When new drive belt is installed, the indicator should be within the range (B) in the figure.
 Visually check entire drive belt for wear, damage or cracks.
 If the indicator is out of the possible use range or belt is damaged, replace drive belt.

ENGINE MAINTENANCE
 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.
ENGINE COOLANT : DrainingINFOID:0000000003862450
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. Check drained engine coolant for contaminants such as rust, corrosion or discoloration.
If contaminated, flush the engine cooling system. Refer to MA-16, "
ENGINE COOLANT : Flushing".

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".
6. Install air duct assembly and air cleaner cases (upper and lower) assembly. Refer to EM-26, "
Exploded
View".
7. Install radiator cap.
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.

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.
ENGINE COOLANT : FlushingINFOID:0000000003862452
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-110, "
Dis-
assembly and Assembly".
2. Remove air duct assembly and air cleaner cases (upper and lower) assembly. Refer to EM-26, "

3. Disconnect heater hose (1) at the position ( ) in the figure.
4. Fill radiator and reservoir tank with water and reinstall radiator cap.
CAUTION:
Never adhere the water to electronic equipments. (alternator etc.)
When water overflows disconnected heater hose, connect heater hose, and continue filling the
water.
5. Run the engine and warm it up to normal operating temperature.
6. Rev the engine two or three times under no-load.
7. Stop the engine and wait until it cools down.
8. Drain water from the system. Refer to MA-14, "
ENGINE COOLANT : Draining".

plunger (B) cannot be seen when watching it vertically from the
top.
- Check if valve seat has no soil and damage.
- Check that there is no dirt or damage on the valve seat of radiator
cap negative-pressure valve.
- Check that there are no unusualness in the opening and closing
conditions of negative-pressure valve.
 Check radiator cap relief pressure.
- When connecting radiator cap to the radiator cap tester (commer-
cial service tool) and the radiator cap tester adapter (commercial
service tool) (A), apply engine coolant to the cap seal surface.
 Replace radiator cap if there is an unusualness related to the above three.
CAUTION:
When installing radiator cap, thoroughly wipe out the radiator pipe (upper) filler neck to remove any
waxy residue or foreign material.
RADIATOR
RADIATOR : InspectionINFOID:0000000003862454

 When radiator is cleaned without removal, remove all surrounding parts such as radiator cooling fan
assembly and horns. Then tape harness and connectors to prevent water from entering.
1. Apply water by hose to the back side of the radiator core vertically downward.
2. Apply water again to all radiator core surfaces once per minute.
3. Stop washing if any stains no longer flow out from radiator.
