assembly.
ACCUMULATOR : InspectionINFOID:0000000006256026
INSPECTION AFTER REMOVAL
 O-ring must be free of scratches and damage.
 Pipe and tube must be free of scratches and damage.
INSPECTION AFTER INSTALLATION
Check oil leakage, twists, deformation, cont act with other parts, and loose connections.
ADJUSTMENT AFTER INSTALLATION
Perform air bleeding. Refer to SCS-18, "Work Procedure".
ACCUMULATOR : DisposalINFOID:0000000006256027
CAUTION:
 Always wear safety goggles.
 Always wear safety gloves.
 Be careful since pressure is higher when temperature is high.
 Be careful since metal shavings or oi l may be blown away by compressed gas.
 Discard drained oil in accordance with local laws and regulations.
WORK PROCEDURE
1. Remove both tanks using an oil filter wrench.
2. Secure tank using a vise.
3. Drill a hole as shown in the figure ( z) using an electric drill.
Drain gas and oil.
NOTE:
 Gas is colorless, odorless, and harmless.
 Use an electric drill with a drill bit of approximately 4 mm (0.16 in).
 Drilling a hole is easier when electric drill speed is slow.

A/T FLUID COOLER
DIAGNOSIS PROCEDURE
NOTE:
Insufficient cleaning of the cooler inlet hose exte
rior may lead to inaccurate debris identification.
1. Position an oil pan under the A/T inlet and outlet cooler hoses.
2. Clean the exterior and tip of the cooler inlet hose.
3. 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.
 Never breath vapors or spray mist.
4. 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 ATF flows out of the cooler inlet hose for 5 seconds.
5. Tie a common white, basket-type coffee filter to the end of the cooler inlet hose.
6. Insert the tip of an air gun into the end of the cooler outlet hose.
7. Wrap a shop rag around the air gun tip and end of cooler outlet hose.
8. Blow compressed air regulated to 5 to 9 kg/cm
2 (71 to 128 psi)
through the cooler outlet hose to force any remaining ATF into
the coffee filter.
9. Remove the coffee filter from the end of the cooler inlet hose.
10. Perform “INSPECTION PROCEDURE”.
INSPECTION PROCEDURE
1. Inspect the coffee filter for debris.
a. If small metal debris less than 1 mm (0.040 in) in size or metal powder is found in the coffee filter, this is normal. If normal
debris is found, the A/T fluid cooler/radiator can be re-used and
the procedure is ended.
