A/T Fluid Cooler CleaningUCS002CA
Whenever an automatic transmission 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 become trapped in the A/T fluid cooler. This debris can con-
taminate the newly serviced A/T or, in severe cases, can block 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 cooler 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. Position an oil pan under the automatic transmission's inlet and outlet cooler hoses.
2. Identify the inlet and outlet fluid cooler hoses.
3. Disconnect the 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 cooler cleaner only with adequate ventilation.

Avoid contact with eyes and skin.

Do not breath 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 fluid flows out of the 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 of the cooler outlet
hose.
9. Blow compressed air regulated to 5 - 9 kg/cm
2 (70 - 130 psi) through the cooler outlet hose for 10 sec-
onds to force out any remaining fluid.
10. Repeat steps 5 through 9 three additional times.
11. Position an oil pan under the banjo bolts that connect the fluid cooler steel lines to the transmission.
12. Remove the banjo bolts.
13. Flush each steel line from the cooler side back toward the transmission by spraying Transmission Cooler
Cleaner in a continuous stream for 5 seconds.

14. Blow compressed air regulated to 5 - 9 kg/cm2 (70 - 130 psi) through each steel line from the cooler side
back toward the transmission for 10 seconds to force out any remaining fluid.
15. Ensure all debris is removed from the steel cooler lines.
16. Ensure all debris is removed from the banjo bolts and fittings.

A/T FLUID COOLER DIAGNOSIS PROCEDURE" .
A/T FLUID COOLER DIAGNOSIS PROCEDURE
NOTE:
Insufficient cleaning of the cooler inlet hose exterior may lead to inaccurate debris identification.
1. Position an oil pan under the automatic transmission's 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 cooler cleaner only with adequate ventilation.

Avoid contact with eyes and skin.

Do not 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 fluid 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 - 9 kg/cm
2 (70 - 130 psi)
through the cooler outlet hose to force any remaining A/T fluid
into the coffee filter.
9. Remove the coffee filter from the end of the cooler inlet hose.

Removal and InstallationEIS002UL
REMOVAL
1. Remove inside mirror. Refer to GW-77, "Removal and Installation" .
2. Partially remove the headlining (front edge). Refer to EI-37, "
HEADLINING" .
3. Remove cowl top cover. Refer to EI-18, "
Removal and Installation" .
4. Apply a protective tape around the windshield glass to protect the painted surface from damage.

Remove glass using piano wire or power cutting tool and an inflatable pump bag.

If a windshield glass is to be reused, mark the body and the glass with mating marks.
WA RN ING:
When cutting the glass from the vehicle, always wear safety glasses and heavy gloves to help prevent
glass splinters from entering your eyes or cutting your hands.
CAUTION:

When a windshield glass is to be reused, do not use a cutting knife or power cutting tool.

Be careful not to scratch the glass when removing.

Do not set or stand glass on its edge. Small chips may develop into cracks.
INSTALLATION

Use a genuine NISSAN Urethane Adhesive Kit (if available) or equivalent and follow the instructions fur-
nished with it.

While the urethane adhesive is curing, open a door window. This will prevent the glass from being forced
out by passenger compartment air pressure when a door is closed.

The molding must be installed securely so that it is in position and leaves no gap.
