REVISION SUMMARY
•

There are extensive updates and American Honda recommends you review the entire bulletin.

•

TOOLS INFORMATION had critical information change, as highlighted in yellow.

BACKGROUND
Due to a new North America regulation that introduces a new refrigerant and oil requirement, the compressor shaft seal
may leak. American Honda is extending the warranty on the A/C compressor shaft seal from the original 3 years to 10
years from the original date of purchase, with no mileage limitation.
The new refrigerant and oil may cause swelling of the compressor shaft seal. The swelling may lead to abnormal
wearing of the seal, which may increase seal gaps around the compressor shaft allowing refrigerant to leak out.
This warranty extension will not apply to any vehicle that has ever been declared a total loss or sold for salvage by a
financial institution or insurer or has a branded or similar title under any state’s law.

CUSTOMER NOTIFICATION
Owners of affected vehicles will be sent a notification of this campaign.
Do an iN VIN status inquiry to make sure the vehicle is shown as eligible.

CORRECTIVE ACTION
Do the inspection procedure and if directed, replace the compressor shaft seal.

CUSTOMER INFORMATION:The information in this bulletin is intended for use only by skilled technicians who have the proper tools, equipment, and
training to correctly and safely maintain your vehicle. These procedures should not be attempted by “do-it-yourselfers,” and you should not assume this
bulletin applies to your vehicle, or that your vehicle has the condition described. To determine whether this information applies, contact an authorized
Honda automobile dealer.

INSPECTION PROCEDURE
1. Remove the right-front tire.
2. Remove the engine undercover.

3. Remove the front subframe brace.

4. Remove the drive belt.

Page 4 of 26

5. Inspect for oil on the armature plate surface of the compressor.

NOTE: If any oil is stuck to the armature plate surface of the compressor, then proceed to the repair procedure.

Page 5 of 26

6. If no oil is noticed, leave the compressor on the vehicle. Remove the center hub bolt and armature plate from the
compressor. Then, inspect both for oil.
NOTE:
•

If oil is present on the hub/armature plate, then proceed to the repair procedure.

•

If no oil is present, then proceed to step 7.

Examples of dry and oily clutch assemblies.

7. Remove the felt washer from the compressor and gently place it on a clean sheet of copier paper.
NOTE: If oil transfers from the felt washer to the paper after 10 seconds, proceed to the repair procedure. If not,
proceed to step 8.

Page 7 of 26

8. Using a calibrated leak detector, check for a leak.
NOTE:
•

Use a leak detector for at least 5 minutes around the snout of the compressor.

•

An A/C compressor that has not been engaged will yield better results. The longer the A/C compressor has not
been run, the better chance you will have at detecting a leak.

•

A higher engine temperature produces more accurate results.

•

If a leak is detected, proceed to the repair procedure.

9. If no oil leak is found, reassemble the armature plate with the original bolt and torque to 17 N.m (13 lb-ft).

If this is a second time and no leak is found, reassemble the hub/armature plate with a new bolt and torque
to 17 N.m (13 lb-ft).
NOTE:
•

Verify the armature plate and pulley rotate smoothly and independently.

•

Measure the clearance between the pulley and armature plate all the way around. If clearance is not within
specified limits, remove the armature plate and add/or remove shims as needed.

•

Clearance: 0.30–0.60mm (0.012–0.024in).

•

Shims are available in three sizes: 0.3mm, 0.4mm, 0.5mm.

10. Install the drive belt, run the vehicle for ten minutes and redo step 8 again.
NOTE: If no leak or oil found after completing the second time, then continue with the normal leak check procedure
of other A/C components.

REPAIR PROCEDURE

Chance for fluids to enter eyes and/or hands which can cause injury. Use safety glasses and rubber gloves.
Click here to view a video of the seal repair procedure:
1. Connect an A/C recover/recycle/recharge machine to the high-pressure service port and the low-pressure service
port following the equipment manufacturer instructions.

2. Recover the A/C refrigerant.

Page 9 of 26

3. Disconnect the discharge and suction hoses.
NOTE: Use the port plugs in the seal assembly kit to immediately seal the ports after disconnection. This avoids
moisture and dust contamination from entering the air conditioning compressor. Installing an A/C compressor into a
contaminated system can result in premature A/C compressor failure.

4. Remove the A/C compressor.

Page 10 of 26

5. If the clutch has not been removed from a previous step, remove the clutch center flange bolt (17 N.m 13 lb-ft).

6. If the clutch has not been removed from a previous step, remove the clutch while being careful not to drop/lose any
shims (usually 1–2).

7. If the felt washer has not been removed from a previous step, use a pick to remove the felt washer.

8. Remove the pulley C-ring.

Page 12 of 26

9. Remove the pulley.

10. Remove the seal C-ring.

Page 13 of 26

11. Thoroughly clean the bore and shaft with a lint free cloth.
NOTE: Do not use compressed air. The bore needs to be very clean as to prevent debris from entering the
compressor once the seal is removed. Failure to remove all debris will result in future failure.

12. Remove the side bracket (1.5L engine only).

Page 14 of 26

13. Place the press tool onto the A/C compressor and insert the holding pins (2). Make sure the press tool installs
where the press shaft should align with compressor shaft. The press tool will only align correctly in one orientation.
The pins must go all the way through.
NOTE: The part numbers for the press tool are: 1.5T tool: 07AAD-5AAA101, 2.0 tool: 07AAD-5BAA100, and 2.0T
tool: 07AAD-5BAA100.

Page 16 of 26

15. Add grease to the press adapter button and press threads.

16. Tighten the press until there is no clearance, then 3/4 turn (270°).
NOTE:
•

The purpose of this step is to break the compressor shaft seal loose.

•

Turning the handle more than 3/4 turn (270°) can damage the tool and seal making it difficult to remove the
compressor shaft seal.

17. Release to remove the adapter and press tool.

18. Insert the cylinder tool onto the A/C compressor.

Page 18 of 26

19. Insert the extractor tool, and make sure the 24 mm nut is positioned towards the top. Look into the cylinder window
to align the extractor tool onto the flange and press the handle fully down to grab the seal.
NOTE: The 24 mm nut will use a 36 mm wrench.

20. Stabilize the extractor tool using a 19 mm wrench on the top. Then, turn the handle clockwise until resistance is felt.
Make sure that the space between the 19 mm wrench and the bottom portion of the extractor tool is minimal.
NOTE: To confirm the extractor is engaged, hold the extractor tool and lift the compressor up.

Page 19 of 26

21. Apply grease between the 24 mm nut and cylinder as well as cylinder top.

Page 20 of 26

22. With the 19 mm wrench in place, lower the 24 mm nut down until it reaches the cylinder. Slowly and carefully adjust
until the extractor tool comes out freely with the seal.
NOTE:
•

Resistance will be felt while lowering 24 mm nut and will cease once the seal is extracted.

•

If the seal does not come out on the first step, repeat the process starting at step 13.

23. Thoroughly clean the bore and shaft with a lint free cloth.
NOTE: Do not use compressed air. The bore needs to be very clean as to prevent debris from entering the
compressor once the seal is installed. Failure to remove all debris will result in future failure.

24. Inspect the compressor shaft bore for visible damage; Inspect the seal guide for contamination or damage.
25. Lubricate the new seal outer surface, seal guide, and bore with new POE compressor oil.
NOTE:
•

Avoid touching the center of the seal to prevent cross-contamination of the A/C refrigerant system.

•

Make sure to clean the surface using clean gloves and with a lint free cloth before lubrication.

26. Insert the seal guide tool onto A/C compressor shaft.

27. Insert the new seal onto the seal guide tool.
NOTE: The seal is directional and must be placed with the metal side upwards as shown below.

Page 23 of 26

28. Insert the press adapter tool over the seal guide. By hand, press down just enough to seat and install the new seal.
NOTE: Seat the seal about 5 mm below the top edge of the bore.

29. Insert the new seal C-ring with the teeth’s rounded side pointing down into the bore.

Page 24 of 26

30. Add the press tool.

31. Tighten the press by rotating the handle clockwise until it reaches the adapter tool. Slowly and carefully continue to
rotate the handle clockwise until the seal is pressed down roughly 10 mm below the top edge of the bore.
NOTE: Tighten the press until the C-clip is installed into the clip groove. There will be a sound or vibration felt when
the C-clip is fully set.

32. Remove the press and the adapter tool when successfully completed.
33. Clean the pulley and A/C compressor friction surfaces with Honda Brake Cleaner or equivalent.
