A/T FLUID
5. Run engine at idle speed for 5 minutes.
6. Check A/T fluid level and condition. Refer to AT-17, "
Checking A/T Fluid".
A/T Fluid Cooler CleaningINFOID:0000000005928072
Whenever the A/T is repaired, overhauled, or replaced, the A/T fluid cooler mounted in the radiator must be
inspected and cleaned.
Metal debris and friction material, if present, can becom e trapped in the A/T fluid cooler. This debris can con-
taminate the newly serviced A/T or, in severe cases, can bloc k or restrict the flow of A/T fluid. In either case,
malfunction of the newly serviced A/T may result.
Debris, if present, may build up as A/T fluid enters the c ooler inlet. It will be necessary to back flush the cooler
through the cooler outlet in order to flush out any built up debris.
A/T FLUID COOLER CLEANING PROCEDURE
1. Identify the A/T inlet and outlet fluid cooler hoses.
2. Position an oil pan under the A/T inlet and outlet fluid cooler hoses.
3. Disconnect the A/T fluid cooler inlet and outlet rubber hoses from the steel cooler tubes or bypass valve.
NOTE:
Replace the cooler hoses if rubber material from the hose
remains on the tube fitting.
4. Allow any A/T fluid that remains in the cooler hoses to drain into the oil pan.
5. Insert the extension adapter hose of a can of Transmission
Cooler Cleaner (Nissan P/N 999MP-AM006) into the cooler out-
let hose.
CAUTION:
• Wear safety glasses and rubber gloves when spraying the Transmission Cooler Cleaner.
• Spray Transmission Cooler Cleaner only with adequate
ventilation.
• Avoid contact with eyes and skin.
• Do not breathe vapors or spray mist.
6. Hold the hose and can as high as possible and spray Transmis- sion Cooler Cleaner in a continuous stream into the cooler outlet
hose until A/T fluid flows out of t he cooler inlet hose for 5 seconds.
7. Insert the tip of an air gun into the end of the cooler outlet hose.
8. Wrap a shop rag around the air gun tip and end of cooler outlet hose.
9. Blow compressed air regulated to 5 - 9 kg/cm
2 (490 - 883 kPa, 71 - 128 psi) through the cooler outlet hose
for 10 seconds to force out any remaining A/T fluid.
10. Repeat steps 5 through 9 three additional times.
11. Position an oil pan under the banjo bolts that connec t the A/T fluid cooler steel lines to the A/T.
12. Remove the banjo bolts. Fluid grade and capacity: Refer to

1. Warm up CVT fluid by driving the vehicle for 10 minutes.
• : Vehicle front
• Radiator (2)
• CVT fluid cooler hose [inlet side (3)]
• Transaxle assembly (4)
2. Drain CVT fluid from CVT fluid cooler hose [outlet side (1)] and refill with new specified NISSAN CVT fluid in the CVT fluid
charging pipe with the engine running at idle speed.
CAUTION:
Only use the specifi ed NISSAN CVT fluid.
3. Refill until new CVT fluid comes out from CVT fluid cooler hose [outlet side (1)]. NOTE:
About 30 to 50% extra fluid will be required for this procedure.
4. Check fluid level and condition. Refer to CVT-14, "
Checking CVT Fluid".
CAUTION:
Delete CVT fluid deterioration date with CONSULT-III after changing CVT fluid. Refer to CVT-48,
"CONSULT-III Function (TRANSMISSION)".
CVT Fluid Cooler CleaningINFOID:0000000005928732
Whenever a CVT is repaired, overhauled, or replaced, the CVT fluid cooler mounted in the radiator must be
inspected and cleaned.
Metal debris and friction material, if present, can be trapped or become deposit in the CVT fluid cooler. This
debris can contaminate the newly serviced CVT or, in severe cases, can block or restrict the flow of CVT fluid.
In either case, malfunction of the newly serviced CVT may occur.
Debris, if present, may deposit as CVT fluid enters the cool er inlet. It will be necessary to back flush the cooler
through the cooler outlet in order to flush out any built up debris.
CVT FLUID COOLER CLEANING PROCEDURE
1. Identify the CVT inlet and outlet fluid cooler hoses.
2. Position an oil pan under the inlet and outlet cooler hoses.

PRECAUTIONS
-
Freeze frame data
- 1st trip freeze frame data
- System readiness test (SRT) codes
- Test values
• When connecting ECM harness connector, fasten (B) it
securely with a lever (1) as far as it will go as shown in the fig-
ure.
- ECM (2)
- Loosen (A)
• When connecting or disconnect ing pin connectors into or
from ECM, take care not to damage pin terminals (bend or
break).
Make sure that there are not any bends or breaks on ECM pin
terminal, when connecting pin connectors.
• Securely connect ECM harness connectors.
A poor connection can cause an extremely high (surge) volt-
age to develop in coil and co ndenser, thus resulting in dam-
age to ICs.
• Keep engine control system harness at least 10 cm (4 in) away
from adjacent harness, to preven t engine control system mal-
functions due to receiving external noise, degraded operation
of ICs, etc.
• Keep engine control system parts and harness dry.
• Before replacing ECM, perform “ECM Terminals and Refer-
ence Value” inspection and m ake sure ECM functions prop-
erly. Refer to EC-605, "
ECM Terminal and Reference Value".
• Handle mass air flow sensor carefully to avoid damage.
• Do not disassemble m ass air flow sensor.
• Do not clean mass air flow sensor with any type of detergent.
• Do not disassemble electric throttle control actuator.
• Even a slight leak in the ai r intake system can cause serious
incidents.
• Do not shock or jar the camshaft position sensor (PHASE),
crankshaft position sensor (POS).
• After performing each TROUBLE DIAGNOSIS, perform DTC
Confirmation Procedure or Overall Function Check.
The DTC should not be displ ayed in the DTC Confirmation
Procedure if the repair is co mpleted. The Overall Function
Check should be a good result if the repair is completed.

• Using a bore gauge, measure the cylinder bore for wear, out-of-
round and taper at six different points on each cylinder. (“X” and
“Y” directions at “A”, “B” and “C”) (“Y” is in longitudinal direction of
the engine)
NOTE:
When determining cylinder bore grade, measure cylinder bore at
“B” position.
• If the measured value exceeds the limit, or if there are scratches and/or seizure on the cylinder inner wall,
replace cylinder block.
NOTE:
There is no service setting for oversized piston.
Piston Skirt Diameter
Measure the outer diameter of piston skirt with a micrometer.
Piston to Cylinder Bore Clearance
Calculate by piston skirt diameter and cylinder bor e inner diameter (direction “X”, position “B”).
(Clearance) = (Cylinder bore inner di ameter) – (Piston skirt diameter)
• If it exceeds the limit, replace piston and piston pin assembly and/or cylinder block.
CRANKSHAFT MAIN JOURNAL DIAMETER
• Measure the outer diameter of crankshaft main journals with a micrometer (A).
• If out of the standard, measure the main bearing oil clearance. Then use undersize bearing.
