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".

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

 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.

RADIATOR CAP : InspectionINFOID:0000000003862453
 Check valve seat (A) of radiator cap.
- Check if valve seat is swollen to the extent that the edge of the
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
Check radiator for mud or clogging. If necessary, clean radiator as follows:
CAUTION:
 Be careful not to bend or damage radiator fins.
 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.
4. Blow air into the back side of radiator core vertically downward.
 Use compressed air lower than 490 kPa (4.9 bar, 5 kg/cm
2, 71 psi) and keep distance more than 30 cm
(11.81 in).
5. Blow air again into all the radiator core surfaces once per minute until no water sprays out.

level is within the specified range.
CAUTION:
When reinstalling CVT fluid level gauge, insert it into the
CVT fluid charging pipe and rotate it to the original installa-
tion position until securely locked.
CVT FLUID CONDITION
Check CVT fluid condition.
 If CVT fluid is very dark or smells burned, check operation of CVT.
Flush cooling system after repair of CVT.
 If CVT fluid contains frictional material (clutches, brakes, etc.),
replace radiator and flush cooler line using cleaning solvent and
compressed air after repair of CVT. Refer to CO-13, "
Exploded

CVT FLUID: RE0F10A : ChangingINFOID:0000000003862428
CAUTION:
Replace O-ring with new ones at the final stage of the operation when installing.
1. Remove drain plug from oil pan.
2. Remove drain plug gasket from drain plug.
3. Install drain plug gasket to drain plug.
CAUTION:
Never reuse drain plug gasket.
4. Install drain plug to oil pan. Refer to TM-321, "

5. Fill CVT fluid from CVT fluid charging pipe to the specified level.
CAUTION:
 Use only Genuine NISSAN CVT Fluid NS-2. Never mix with other fluid.
 Using CVT fluid other than Genuine NISSAN CVT Fluid NS-2 will deteriorate in driveability and
CVT durability, and may damage the CVT, which is not covered by the warranty.
 When filling CVT fluid, take care not to scatter heat generating parts such as exhaust.
 Sufficiently shake the container of CVT fluid before using.
 Delete CVT fluid deterioration date with CONSULT-III after changing CVT fluid.

Again, pressing on the components to stop the noise while duplicating the conditions can isolate most of these
incidents. Repairs usually consist of insulating with felt cloth tape.
SEATS
When isolating seat noise it is important to note the position the seat is in and the load placed on the seat
when the noise occurs. These conditions should be duplicated when verifying and isolating the cause of the
noise.
Cause of seat noise include:
1. Headrest rods and holder
2. A squeak between the seat pad cushion and frame
3. Rear seatback lock and bracket
These noises can be isolated by moving or pressing on the suspected components while duplicating the con-
ditions under which the noise occurs. Most of these incidents can be repaired by repositioning the component
or applying urethane tape to the contact area.
UNDERHOOD
Some interior noise may be caused by components under the hood or on the engine wall. The noise is then
transmitted into the passenger compartment.
Causes of transmitted underhood noise include:
1. Any component mounted to the engine wall
2. Components that pass through the engine wall
3. Engine wall mounts and connectors
4. Loose radiator mounting pins
5. Hood bumpers out of adjustment
6. Hood striker out of adjustment
These noises can be difficult to isolate since they cannot be reached from the interior of the vehicle. The best
method is to secure, move or insulate one component at a time and test drive the vehicle. Also, engine RPM
or load can be changed to isolate the noise. Repairs can usually be made by moving, adjusting, securing, or
insulating the component causing the noise.
