On Board Diagnosis LogicNJEC0663This diagnosis continuously monitors the engine coolant temperature.
If the cooling fan or another component in the cooling system malfunctions, engine coolant temperature will
rise.
When the engine coolant temperature reaches an abnormally high temperature condition, a malfunction is
indicated.

For more information, refer to ªMAIN 12 CAUSES OF
OVERHEATINGº, EC-633.
CAUTION:
When a malfunction is indicated, be sure to replace the coolant following the procedure in the LC-43,
ªChanging Engine Coolantº. Also, replace the engine oil.
1) Fill radiator with coolant up to specified level with a filling speed of 2 liters per minute. Be sure
to use coolant with the proper mixture ratio. Refer to MA-22, ªEngine Coolant Mixture Ratioº.
2) After refilling coolant, run engine to ensure that no water-flow noise is emitted.

Overall Function CheckNJEC0664Use this procedure to check the overall function of the cooling fan.
During this check, a DTC might not be confirmed.
WARNING:
Never remove the radiator cap when the engine is hot. Serious
burns could be caused by high pressure fluid escaping from
the radiator.
Wrap a thick cloth around the cap. Carefully remove the cap
by turning it a quarter turn to allow built-up pressure to
escape. Then turn the cap all the way off.
WITH CONSULT-IINJEC0664S011) Check the coolant level in the reservoir tank and radiator.
Allow engine to cool before checking coolant level.
If the coolant level in the reservoir tank and/or radiator is below
the proper range, skip the following steps and go to ªDiagnos-
tic Procedureº, EC-622.
2) Confirm whether customer filled the coolant or not. If customer
filled the coolant, skip the following steps and go to ªDiagnos-
tic Procedureº, EC-622.
3) Turn ignition switch ªONº.
4) Perform ªCOOLING FANº in ªACTIVE TESTº mode with CON-
SULT-II and make sure that cooling fans operate when touch-
ing ªHIGHº or ªLOWº.
If NG, go to ªDiagnostic Procedureº, EC-622.
WITHOUT CONSULT-IINJEC0664S021) Check the coolant level in the reservoir tank and radiator.
Allow engine to cool before checking coolant level.
If the coolant level in the reservoir tank and/or radiator is below
the proper range, skip the following steps and go to ªDiagnos-
tic Procedureº, EC-622.
2) Confirm whether customer filled the coolant or not. If customer
filled the coolant, skip the following steps and go to ªDiagnos-
tic Procedureº, EC-622.
3) Start engine.
Be careful not to overheat engine.
4) Set temperature control lever to full cold position.
5) Turn air conditioner switch ªONº.

SMA827CA
Checking A/T FluidNJAT02281. Warm up engine.
2. Check for fluid leakage.
3. Before driving, fluid level can be checked at fluid temperatures
of 30 to 50ÉC (86 to 122ÉF) using ªCOLDº range on dipstick.
a. Park vehicle on level surface and set parking brake.
b. Start engine and move selector lever through each gear posi-
tion. Leave selector lever in ªPº position.
c. Check fluid level with engine idling.
d. Remove dipstick and note reading. If level is at low side of
either range, and fluid to the charging pipe.
e. Re-insert dipstick into charging pipe as far as it will go.
f. Remove dipstick and note reading. If reading is at low side of
range, add fluid to the charging pipe.
Do not overfill.
4. Drive vehicle for approximately 5 minutes in urban areas.
5. Re-check fluid level at fluid temperatures of 50 to 80ÉC (122
to 176ÉF) using ªHOTº range on dipstick.
SMA853B
6. Check fluid condition.
+If fluid is very dark or smells burned, refer to AT section for
checking operation of A/T. Flush cooling system after repair of
A/T.
+If A/T fluid contains frictional material (clutches, bands, etc.),
replace radiator and flush cooler line using cleaning solvent
and compressed air after repair of A/T. Refer to LC-16, ªRadia-
torº.
SMA027D
Changing A/T FluidNJAT02291. Warm up A/T fluid.
2. Stop engine.
3. Drain A/T fluid from drain plug and refill with new A/T fluid.
Always refill same volume with drained fluid.
Fluid grade:
Nissan Matic ªDº or Genuine Nissan Automatic
Transmission Fluid. Refer to ªRECOMMENDED FLU-
IDS AND LUBRICANTSº, MA-20.
Fluid capacity (With torque converter):
7.0!(6-1/8 Imp qt)
Drain plug:
: 29 - 39 N´m (3.0 - 4.0 kg-m, 22 - 29 ft-lb)
4. Run engine at idle speed for five minutes.
5. Check fluid level and condition. Refer to ªChecking A/T Fluidº.
If fluid is still dirty, repeat steps 2 through 5.

5. Set manual shaft to ªPº position.
6. Remove PNP switch.
SAT128E
7. Remove oil pan and oil pan gasket.
+Do not reuse oil pan bolts.
8. Check foreign materials in oil pan to help determine cause of
malfunction. If the fluid is very dark, smells burned, or contains
foreign particles, the frictional material (clutches, band) may
need replacement. A tacky film that will not wipe clean indi-
cates varnish build up. Varnish can cause valves, servo, and
clutches to stick and may inhibit pump pressure.
+If frictional material is detected, replace radiator after
repair of A/T. Refer to LC-16, section ªRadiatorº.
9. Remove control valve assembly according to the following pro-
cedures.
AAT260A
a. Remove control valve assembly mounting bolts A, B and C.

Precautions
PRECAUTIONSNJAX0001+When installing rubber parts, final tightening must be car-
ried out under unladen condition* with tires on ground.
*: Fuel, radiator coolant and engine oil full. Spare tire, jack,
hand tools and mats in designated positions.
+After installing removed suspension parts, check wheel
alignment and adjust if necessary.
+Use flare nut wrench when removing or installing brake
tubes.
+Always torque brake lines when installing.
