ALL INFINITI: REMOVAL OF ENVIRONMENTAL IRON PARTICLES FROM PAINT

This bulletin has been amended. Please discard paper copies of all earlier versions.

APPLIED VEHICLE:All Infiniti Vehicles

IF YOU CONFIRM:

There are environmental particles in the paint.

NOTE: Environmental particles can be identified as follows:

- On light-colored painted surfaces: Small rust/orange dots with black centers on light colored surfaces,

- On dark-colored painted surfaces: Small white or silver dots with a "rainbow hue" around the edge on dark colored surfaces.

In both cases, the surface will feel rough or gritty to the touch.

ACTION:

Perform the steps in the Service Procedure.

NOTE: The steps in the Service Procedure have been found effective in most cases for removing environmental iron particles (sometimes called

"rail dust") from a vehicle's painted surfaces.

Refer to the Claims Information section on page 2 of this bulletin for important claims information concerning environmental claims.

IMPORTANT: The purpose of "ACTIONS" (above) is to give you a quick idea of the work you will be performing.

You MUST closely follow the entire Service Procedure as it contains information that is essential to successfully completing this repair.

CLAIMS INFORMATION

Section 1 of the Assurance Products Resource Manual (under "Environmental Damage") states, "Since Environmental Damage is generally excluded

from the Infiniti's New Vehicle Limited Warranty, repairs for such damage do not generally qualify for reimbursement as warranty expense.

SERVICE PROCEDURE

CAUTION: In most cases these environmental iron particles can be easily removed. However, the longer they are left untreated, the more damage

they can create, and the harder they are to remove. In rare, more severe cases, spots of paint blistering can occur.

1. Use a magnifying glass to check if iron particles are present.

2. Wash the vehicle with soap and warm water. Completely dry the vehicle.

NOTE: There are 3 Steps of damage repair possible that should be completed in the order given.

225

- Start with Step A first.

- Complete Step B if necessary.

- Go to Step C only if iron particles are not removed in Steps A and B.

3. Repair the paint damage.

Step A. Light/Medium Damage (surface level only)

Remove the iron particles using a clay bar such as Clay Magic(R) by Auto Wax Company, Inc., SPC40 Overspray Clay by PPG, a "clay like"

surface cleaning material such as Erazer(R) by K.E. L. Mfg., or equivalent.

WARNING: Read and follow the manufacturer's procedure before using the chemicals listed above.

Step B. Medium Damage (surface level only)

Remove the iron particles using a chemical cleaning product such as:

- An industrial fallout remover (i.e. oxalic acid) such as Zep Industrial Fallout Remover(R) X-20472 by Zep Manufacturing Company or

equivalent; or

- A chemical neutralization system such as ValuGard(R) 3-Step Neutralization/Decontamination System by Automotive International, Inc.,

or equivalent.

WARNING: Read and follow the manufacturer's procedure before using the chemicals listed above.

Step C. Heavy Damage (deep into the clear and/or color coat)

This step will require wet sanding and/or repainting. Contact your local paint refinish supplier for recommended procedures such as BASF

Corporation Rail Dust repair procedure, Sherwin-Williams Ultra 7000 Basecoat System or equivalent.

CAUTION: Only an experienced paint technician, who is familiar with proper refinishing techniques, should perform the above repair.

Manual, P/N 5PII00. Call Resolve Corporation: 1-800-247-5321 for a copy of the Nissan/Infiniti Paint Incident Identification Manual, P/N

REMOVAL PROCEDURE FOR SEIZED EXHAUST SENSOR

APPLIED VEHICLES:

All Infiniti vehicles

SERVICE INFORMATION

If an exhaust sensor is seized in the exhaust manifold/catalyst/front tube perform the procedure described in this bulletin to remove the sensor and

prevent unnecessary replacement of the exhaust manifold/catalyst/front tube.

In most cases this procedure is successful. This is because the threads of the exhaust sensors are made of a softer material than the part they thread

into on the exhaust manifold/catalyst/front tube.

NOTE:

The replacement of exhaust manifolds/catalysts/front tubes for stripped exhaust sensor threads may not be considered a warrantable expense.

This procedure can be performed by two methods:

Method # 1. If the Sensor Can Be Easily Accessed

^ The procedure can be performed on the vehicle.

^ The exhaust manifold/catalyst/front tube will not have to be removed.

Method # 2. If the Sensor Cannot Be Easily Accessed

^ The exhaust manifold/catalyst/front tube must be removed from the vehicle.

^ The procedure will be performed with the part clamped in a vice.

Method # 2 is described in this bulletin. Method # 1 is the same as Method # 2 except that it is performed on the vehicle.

SERVICE PROCEDURE

Rust Penetrant

Recommended rust penetrants to be used in this procedure:

NOTES:

^ Rust penetrant is considered a shop supply.

^ Nissan Rust Penetrant can be ordered through the Nissan Direct Ship Chemical Care Product Program: Website order via link on dealer

portal.

^ WD-40 is available from various local sources.

Removal Tool

^ When removing a seized exhaust sensor with a specialty socket (which contains a slit to accommodate the wiring harness) it may spread open

and strip the sensor.

^ Before this occurs it is recommended to cut the wiring harness from the sensor and use a box end wrench or 6-point deep well socket.

1. Clamp the exhaust manifold/catalyst/front tube in a vice.

410

2. Spray the sensor with the rust penetrant for 2 to 3 seconds.

^ It is important that the spray is directed at the base of the sensor to ensure it penetrates into the threads.

3. Loosen the sensor approximately 10 degrees.

4. Spray with rust penetrant again for 2 to 3 seconds.

5. Tighten the sensor 10 degrees then loosen the sensor 10 degrees.

^ Repeat this motion several times until the sensor begins to turn more easily.

6. Continue the tightening/loosening motion while gradually unscrewing the sensor. Stop when the sensor will not unscrew any further.

7. Spray with rust penetrant again for 2 to 3 seconds.

411

8. Repeat steps 6 and 7 until the sensor is removed.

9. Use compressed air to remove any metal debris from inside the boss threads.

CAUTION:

DO NOT perform this step if the procedure is being done on the vehicle (Method # 1). Doing so may cause metal debris to enter the engine

cylinders.

10. If metal debris remains trapped in the boss threads use a spiral nylon brush to remove it.

11. Spray the boss threads with rust penetrant for 2 to 3 seconds.

12. Run a thread chaser through the boss to clean the threads.

^Use Kent Moore part number J-43897-18 or J43897-12.

13. Use compressed air to remove any remaining debris.

CAUTION:

DO NOT perform this step if the procedure is being done on the vehicle (Method # 1). Doing so may cause metal debris to enter the engine

cylinders.

14. If metal debris remains trapped in the boss threads use a spiral nylon brush to remove it.

15. Tilt the manifold/catalyst/front tube so that the metal debris falls out of the part.

16. Apply compressed air through the boss to blow out any remaining debris.

412

CAUTION:

DO NOT perform this step if the procedure is being done on the vehicle (Method # 1 ). Doing so may cause metal debris to enter the

engine cylinders.

17. Install the new sensor as described in the applicable Electronic Service Manual (ESM).
