| SUBJECT: | A/C Compressor- Manufacturing Procedure Change |
INTRODUCTION:
This bulletin announces availability of a new variable displacement type A/C compressor designed to address a small number of customer concerns regarding an excessive sound heard when the system is OFF. The assembly process for the compressor has been changed to prevent occurrence of the condition.
PRODUCTION CHANGE INFORMATION:
The new compressor assembly was incorporated into production starting with VIN NH449077. Production Number inspection is required on all vehicles within the model year range.
PART INFORMATION:
The part number for the new compressor assembly is 73111SJ030.
REMINDER: Always order the most up-to-date replacement parts based on the specific VIN being repaired.
SERVICE PROCEDURE / INFORMATION:
REMINDER: Customer satisfaction and retention starts with performing quality repairs.
After confirming the condition with the A/C system OFF, the production date located on the compressor label must be verified using the illustration below.
IMPORTANT: The NEW part CANNOT be identified by the Part Number. The production date code located on the compressor must be used. In this example (112835535), the “1” indicated the production year as 2021 (a “9” would be 2019, etc.). The next 2 digits, “12” indicate December as the production month (“01” would be January, etc.).
The staring date code / Serial Number for the new compressors is: 0087064586 and after.
1 = Production Year (2021)
12 = Production Month (December)
835535 = Serial Number
After confirming the customer’s sound concern AND the label Serial Number is determined to be BEFORE 0087064586, proceed with replacing the A/C compressor assembly following the procedure in the applicable Service Manual.
The service procedures for A/C compressor replacement remain unchanged. Always refer to the applicable Service Manual and review the full requirements of the repair being performed. The Service Manual procedures contain information critical to performing an effective repair the first time, every time. This includes important SAFETY precautions, proper inspection criteria, necessary special tools, required processes and related one-time-use parts needed for a complete and lasting repair.

- GREEN REFRIGERATION SOLUTION: ZeroR AC Refrigerant is a 100% natural hydrocarbon gas, offering a more eco-friendly alternative to traditional AC recharge like R134a. It helps reduce environmental impact while providing reliable cooling performance
- R134A READY INSTALLATION: Designed to fit R134a systems, ZeroR AC Refrigerant installs just like any standard refrigerant. The cans feature R134a-compatible threads, ensuring easy and seamless installation with your existing R 134a refrigerant can taps
- SMALLER CAN BIGGER IMPACT: Each can of our car AC refrigerant holds 6oz of refrigerant, but its performance is equivalent to 16oz of R134a. This makes it a highly efficient and cost-effective option, requiring less product while maintaining excellent performance
- BUILT FOR SAFE USAGE: ZeroR AC Car Refrigerant is rated with a class 2.1 rating, similar to newer refrigerants. When used in systems designed for refrigerants, it’s safe and poses no danger to users under normal operating conditions
- REGULATED FOR LEGAL SAFETY: ZeroR AC Recharge Can is approved for use in R134a systems only, in compliance with EPA regulations. It ensures proper functionality without the risk of mixing refrigerant types, providing peace of mind and legal safety

- ENGINEERED R134a REPLACEMENT - HIGH-EFFICIENCY FORMULATION - Hydrocarbon-based A/C refrigerant engineered to replace R134a cooling performance when used correctly. Designed for A/C systems originally charged with R134a and serviced by informed DIY users
- PREMIUM HIGH-PURITY SPECIFICATION (99.5%+) - Manufactured to a tightly controlled formula with purity exceeding common refrigerant standards (AHRI 700). No mystery fillers, moisture contamination, or inconsistent blends found in low-grade alternatives
- SIGNIFICANTLY LOWER CHARGE WEIGHT REQUIRED- Hydrocarbon refrigerants absorb more heat per ounce than traditional R134a. As a result, substantially less refrigerant is required to achieve comparable cooling performance. Do not charge by R134a weight
- DESIGNED FOR CONSISTENT, EFFICIENT COOLING PERFORMANCE- Higher heat absorption per unit mass can deliver equal or colder vent temperatures than R134a in many systems when properly charged. Reduced compressor load and efficient evaporator heat transfer contribute to fast pull-down and stable cooling
- PROFESSIONAL-STYLE SELF-SEALING VALVE- 6 oz net cans feature a self-sealing female valve with standard ½″ ACME threads, compatible with common R134a charging hoses. No puncture cans, no special adapters required
- R134a Replacement - Hydrocarbon blend that is 100% natural, safe for the ozone and non global warming. Chemically compatible with R134a systems.
- 6oz (11.7 fl oz) Cans - Compressed gas is measured by weight. This gas is light weight compared to others, but has the same "volume". Guaranteed that you will use no more than normal
- SSV Cans - Self Sealing Valve allows for the storage of unused gas. Requires SSV compatible tool. Avoid "piercing" style tools or the gas may come out slowly or not at all.
- Disclosures - Product is flammable like many other modern refrigerants. Observe all precautions on the product lablel when handling and storing. Follow all legal requirements when charging your system. Hydrocarbon blend refrigerant for NON MVAC use in 6oz SSV Cans.
- Wide Compatibility --- The AC recharge hose with gauge completed with R134A self-sealing refrigerant can opener tap dispensing valve with 1/2” thread, for use in adding R134A refrigerant to vehicle or home air-conditioning with highly working performance
- Easy to Use --- The car ac recharge kit are designed with 90-degree push & lock coupler with auto shut off. Easy and convenient to use. Come with gauge for easily viewing during use and getting a correct charge
- R134A Self-sealing Can Tap --- This can tap can only be use on self-sealing cans with 1/2” thread (Can capacity usual greater than 6OZ or so-called big cans), either cannot be used on puncture style cans
- Premium Quality --- High quality R134A refrigerant freon charge hose with gauge with strong construction.Built-in safety valve to prevent accidental venting of refrigerant
- Package Include ---- With 1/2” ACME Self-Sealing frezon can tap, recharge Hose with gauge and R134A low side quick coupler. Gauge diameter: 5 cm / 1.97 inch, hose length: 34 cm / 13.39 inch, total length: 39 cm / 15.35 inch
