Summary
Service Bulletin – American Honda
is extending the warranty on the A/C condenser to 10 years from the original date of purchase with unlimited miles. This warranty extension only covers vehicles that have a defective A/C condenser from the factory. The A/C condenser was not manufactured to specification. As a result, corrosion may develop in the form of tiny holes in the condenser tube walls that allow the refrigerant to leak out. This does not apply to any vehicle that has a leaking condenser due to foreign object damage. It also does 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.

INSPECTION PROCEDURE
NOTE: Make sure you review the precautions when working with the A/C system.
- Evacuate and recharge the A/C system with the appropriate dye for the vehicle.
NOTE:
- When using the Robinair R-1234yf A/C Recover, Recycle, Recharge Machine, a system vacuum is automatically done when it recharges the system. Use the automatic vacuum check for this bulletin.
- For additional information on how to check if the condenser is leaking, go to service bulletin 07-030 A/C Leak Detection.
- If the refrigerant level is low, the compressor may not activate. Fill the system with enough refrigerant to engage the compressor.
- If there is a large leak in the system, the vacuum leak test may fail and you will be unable to add refrigerant to the system. In that case, continue to step 3, and use the ultrasonic leak detector with the system under vacuum to identify where the leak is. For details on how to use it, watch the Tech2Tech video, “Check for A/C Leaks with the Ultra Sonic Leak Detector.”
- Turn on the A/C, set the climate control to MAX COOL. If equipped, make sure the ECO switch is turned to OFF. NOTE:
- Allow the dye to circulate in the A/C system for a minimum of 60 minutes before inspecting for leaks. Continue to step 3 while the A/C system is circulating the dye.
- If the customer is unable to leave the vehicle for an extended period, have the service advisor schedule a follow-up appointment 24 to 48 hours later.
- Remove the front grille cover.
- Remove the clips and hardware securing the front bumper.
- With the help of an assistant, pull the front bumper away from the side spacers, then release the bumper from the hooks on the upper beam.
With fog lights only: Disconnect the connectors.
- Check for leaks in the central condenser area.
- Check the joints between the horizontal tubes and the vertical pipes.
- Check the inlet and outlet joints and the dryer cap for leaks.
NOTE: Leaks from the O-rings or the receiver/dryer cap are not covered by this bulletin.
Examples of leaks detected with dye
Leaks will appear fluorescent green/yellow under UV light.
Some leaks are visible with the correct angle of UV light. This leak is deep in the groove between fins.
Some leaks may not be visible from certain angles. Aim the UV light from different angles to detect leaks on horizontal tube surfaces.
Some condensers may have multiple leaks.
- If the condenser is leaking, go to the next step.
- If the condenser is not leaking, this bulletin does not apply. Continue with normal troubleshooting.
- Check whether the leak was caused by a foreign object.
There are several types of damage that can result in a leak. This bulletin is for leaks that are caused by the manufacturing process. Damage like those caused by foreign objects that break the tube face are not covered under this warranty extension. A foreign object may damage the fins, but as long as the tube face is not impacted, the leak is covered under this warranty extension.
- Tube face damaged by foreign object – This bulletin does not apply. Continue with normal system troubleshooting.
- Foreign object damage but tube face is not damaged, or the tube face is corroded – Go to REPAIR PROCEDURE.
- No damage or corrosion found but the condenser is leaking – Go to REPAIR PROCEDURE.
REPAIR PROCEDURE
NOTE:
- Only replace the A/C condenser under this warranty extension if it is leaking due to corrosion or manufacturing defect.
- Make sure you review the precautions when working with the A/C system.
- Follow the equipment manufacturer’s instructions, and connect the A/C recover/recycle/recharge machine to the high- pressure service port and the low-pressure service port.
- Recover the refrigerant from the A/C system.
- Measure the amount of refrigerant oil removed from the A/C system after the recovery process is completed. Make sure to put the same amount of new refrigerant oil back into the A/C system before charging.
- Remove the front bumper upper beam.
- With front bumper middle induction plate only: Remove the front bumper middle induction plate.
- Remove the discharge hose from the condenser.
- Remove the receiver pipe from the condenser.
- Remove the A/C condenser.
- Install the new A/C condenser assembly.
- Install all the removed parts in the reverse order of removal.
- Receiver pipe − replace the 8 mm O-ring (80873-ST7-000)
- Discharge hose − replace the 1/2 in O-ring (80872-SN7-003)
- Front bumper middle induction plate (if removed)
- Front bumper upper beam
- Fog light (Connect if disconnected)
- Front bumper
- Front grille cover
NOTE: Torque all fasteners to specification.
- Add the necessary amount of refrigerant oil to the A/C system. Refer to A/C Refrigerant Oil Replacement in the service information.
- Add the necessary amount of refrigerant to the A/C system. Refer to A/C Refrigerant Recovery/Evacuation/Charging in the service information.
- Make sure there are no refrigerant leaks and the A/C system functions properly.

- PERFORMANCE BOOSTER CHARGE KIT - ZeroR is a performance booster for use with R1234YF AC systems. You can use as many cans in your system as you wish, while being sure not to overfill the system with the included can tap with gauge.
- KIT CONTENTS - The can tap is 24 in length with a gauge metered for R1234YF systems. Standard R1234YF can taps will not work on ZeroR branded R1234YF cans, because our cans have a unique thread. 3 cans of ZeroR Permafrost in 4oz cans.
- NOT A Full Refrigerant - This product is a support fluid performance booster. It is a combination of two ZeroR products in one. The first part removes moisture (moisture can cause damage and reduced performance in the system), and the second part reduces friction (friction can reduce refrigerant flow and cause compressor damage)
- 24 in Charging Hose with Can Tap & Gauge - New longer 24 inch connection hose accomodates those harder to reach low side ports that were previously difficult to reach with a shorter 12 inch hose.
- 10 MINUTE INSTALL - Easy instructions are included and will take as little as 10 minutes to complete.
- READY-TO-USE RECHARGE KIT: This all-in-one AC refrigerant recharge kit includes everything you need: 1 can of R1234YF refrigerant and a 24" can tap with gauge. Whether you’re a DIYer or a professional, this kit ensures your AC system stays cool and smooth
- ACCESS HARD-TO-REACH PORTS: The 24-inch heavy-duty brass can tap with a gauge, making refilling your AC system easier. The R1234yf refrigerant kit’s extended hose reaches tight, hard-to-access low-side ports that shorter hoses can't, ensuring a hassle-free process
- ENSURE PEAK AC EFFICIENCY: This kit includes 1 AC recharge can of authentic HFO-R1234YF refrigerant, sourced from authorized suppliers in the USA. Designed for use in R1234YF systems, this refrigerant ensures your vehicle's AC operates at peak efficiency
- ERROR-FREE TOOL CONNECTIONS: The R1234yf refrigerant can tap features a reverse-thread design, ensuring only compatible tools connect to the R1234YF can. This prevents errors, making it safe to connect the refrigerant and perform without risk of incompatibility
- PRECISE REFRIGERANT EVERY TIME: Each refrigerant R-1234yf can contains 8oz of refrigerant, measured by weight for accuracy. Simply use the right amount every time. Most systems require 2-3 cans, and this kit provides everything for a quick, effective recharge
- OEM-Approved R-1234YF Refrigerant – Meets manufacturer specs for factory-installed A/C systems in 2015 and newer vehicles. 12 oz Self-Sealing Can – Compatible with standard R-1234YF recharge tools (not included). Low Global Warming Potential – Helps reduce environmental impact; EPA SNAP-compliant. Reliable Cooling Performance – Designed to restore and maintain optimal air conditioning output. Made by Chemours – A global leader in advanced refrigerant technologies.
- R1234yf Automotive ac REF 8 oz - Qty 1 can with self Sealed Valve Easy use-Made in The USA Safe for Vehicles Replacing R1234YF Diesel or gas.
