Quantity refers to the amount of the service part number required to repair the vehicle.

Unit of Issue refers to the number of individual pieces included in a service part number package.

Piece Quantity refers to the total number of individual pieces required to repair the vehicle.

As Needed indicates the amount of the part may vary and/or is not a whole number. Parts can be billed out as nonwhole numbers, including less than 1.

 

Service Procedure

1. Run the A/C on maximum/recirculation and blower speed on high for at least 10 minutes with the engine idling, then drive the vehicle.

2. Using the datalogger on the appropriate Ford diagnostic scan tool, pull up the EVAP_TEMP PID in the front controls interface module (FCIM) to read the evaporator temperature and use a thermometer to measure the vent outlet temperature. Compare the temperature reading of the EVAP_TEMP PID to the thermometer’s vent outlet temperature reading during A/C use.

3. Is the temperature reading shown on the vent outlet thermometer colder than the temperature reading of the EVAP_TEMP PID?

(1). Yes – proceed to Step 4.

(2). No – if Step 4 directed to restart this article, the repair is complete. For all others, this article does not apply. Refer to the WSM for normal diagnostics.

4. Recover the refrigerant and review recovered refrigerant amount. Was the correct amount recovered within +/- 1 oz. (0.03 kg.)?

(1). Yes – replace the evaporator assembly. Refer to WSM, Section 412-00. The evaporator temperature sensor is part of the evaporator assembly.

(2). No – refer to the WSM for normal diagnostics. Once the root cause of the incorrect charge has been corrected, restart this article from Step 1 to confirm the customer concern is corrected.

ZeroR® Performance Booster Kit for R1234YF Refrigerant AC System | 12" Can Tap Hose Gauge
  • WHAT IS PERMAFROST? - ZeroR Permafrost is a performance booster for R1234YF AC systems. Permafrost synthesizes within the system to make it operate more efficiently, thereby improving cooling potential. Permafrost uses a propellent that is chemically compatible with all R1234YF systems and products. Permafrost compresses into a lighter weight than R1234YF in its liquid state. This lighter weight gas also contributes to its higher efficiency & performance. While this product is not advertised as a "recharge" kit, the gas within the can will provide some charge to your system. You can use as many of these cans in your R1234YF system as you wish.
  • KIT CONTENTS - 3 Cans of ZeroR Permafrost are 4oz by weight. Yes, the cans are full. The can tap is 12” 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.
  • 10 MINUTE INSTALL - While installation times will vary based on experience and condition of the system, installation can often be completed in about 10 minutes. Step by step instructions are included with each purchase. Contact us for any additional assistance by phone, text or email.
  • MOST ECO FRIENDLY - ZeroR Permafrost is 100% natural and does not have any of the below listed risks that R1234YF carries. While R1234YF was an improvement over R134a in that it is non global warming and non ozone depleting, it is still a man made chemical which has proven to be POP, or Persistent Organic Pollutant. That means R1234YF is not biodegradable, can negatively impact water sources and if it does ignite it releases "highly corrosive and toxic hydrogen fluoride and the highly toxic gas carbonyl fluoride". Both R1234YF and ZeroR Permafrost carry a flammable designation.
  • LEGAL: This kit contains flammable contents and should be handled, used and stored in appropriate conditions as outlined on the can label. Most importantly, keep this product in a cool, shaded environment that is away from any ignition source. It is the responsibility of the customer to comply with all Federal, State and Local laws and legislation when purchasing and using any refrigerant. For Washington State compliance, Ingredient List is as follows: (1) 99% Petroleum gas, liquefied; (2) 1% Distillates, petroleum, hydrotreated heavy paraffinic.
