Checking Exhaust System

NLS0007Z

Check exhaust pipes, muffler and mounting for improper attachment,
leaks, cracks, damage, chafing or deterioration.

●

If anything is found, repair or replace damaged parts.

Checking A/T Fluid

NLS00080

Warm up engine.

Check for A/T fluid leakage.

Loosen the level gauge bolt.

Before driving, A/T fluid level can be checked at A/T fluid tem-
peratures of 30 to 50

C (86 to 122

F) using “COLD” range on A/

T fluid level gauge as follows.

Park vehicle on level surface and set parking brake.

Start engine and move selector lever through each gear posi-
tion. Leave selector lever in “P” position.

Check A/T fluid level with engine idling.

Remove A/T fluid level gauge and wipe clean with lint-free
paper.

CAUTION:

When wiping away the A/T fluid level gauge, always use
lint-free paper, not a cloth one.

Re-insert A/T fluid level gauge into A/T fluid charging pipe as far as it will go.

CAUTION:

To check A/T fluid level, insert the A/T fluid level gauge until the cap contacts the end of the A/T
fluid charging pipe, with the A/T fluid level gauge reversed from the normal attachment conditions.

Remove A/T fluid level gauge and note reading. If reading is at low side of range, add ATF to the A/T fluid
charging pipe.

CAUTION:

Do not overfill.

Drive vehicle for approximately 5 minutes in urban areas.

Make the A/T fluid temperature approximately 65

C (149

F).

CHASSIS AND BODY MAINTENANCE

NOTE:
A/T fluid level will be greatly affected by temperature as shown in figure. Therefore, be certain to
perform operation while checking data with CONSULT-II.

Connect CONSULT-II to data link connector. Refer to

AT-92, "CONSULT-II SETTING PROCEDURE"

Select “MAIN SIGNALS” in “DATA MONITOR” mode for “A/T” with CONSULT-II.

Read out the value of “ATF TEMP 1”.

Re-check A/T fluid level at A/T fluid temperatures of approximately 65

C (149

F) using “HOT” range on A/

T fluid level gauge.

CAUTION:

●

When wiping away the A/T fluid level gauge, always use lint-free paper, not a cloth one.

●

To check A/T fluid level, insert the A/T fluid level gauge
until the cap contacts the end of the A/T fluid charging
pipe, with the A/T fluid level gauge reversed from the nor-
mal attachment conditions as shown.

Check A/T fluid condition.

●

If ATF is very dark or smells burned, check 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

CO-14,

"RADIATOR"

(for VQ35DE engine),

CO-43, "RADIATOR"

(for VK45DE engine) and

AT-14, "A/T Fluid Cooler Cleaning"

Install the removed A/T fluid level gauge in the A/T fluid charging
pipe.

Changing A/T Fluid

NLS00081

Warm up ATF.

Stop engine.

Loosen the level gauge bolt.

Drain ATF from drain plug and refill with new ATF. Always refill
same volume with drained ATF.

●

To replace the ATF, pour in new ATF at the A/T fluid charging
pipe with the engine idling and at the same time drain the old
ATF from the radiator cooler hose return side.

●

When the color of the ATF coming out is about the same as
the color of the new ATF, the replacement is complete. The
amount of new ATF to use should be 30 to 50% increase of
the stipulated amount.

CAUTION:

●

Use only genuine NISSAN Matic J ATF. Do not mix with other ATF.

●

Using ATF other than genuine NISSAN Matic J ATF will cause deterioration in driveability and
automatic transmission durability, and may damage the automatic transmission, which is not
covered by the warranty.

●

When filling ATF, take care not to scatter heat generating parts such as exhaust.

●

Do not reuse drain plug gasket.

Run engine at idle speed for 5 minutes.

Check A/T fluid level and condition. Refer to

AT-13, "Checking A/T Fluid"

. If ATF is still dirty, repeat step 2.

through 5.

Install the removed A/T fluid level gauge into A/T fluid charging pipe.

Tighten the level gauge bolt.
