SERVICE INFORMATION

Because of dwindling R-12 supplies, many independent refrigerant manufacturers have developed alternate refrigerants to use in R-12 systems. Some are labeled "EPA-approved," but this only applies to their ozone depletion potential and non-flammability. It doesn't mean they're compatible with Acura A/C systems. If you're thinking of using an alternate refrigerant, consider these things:

1. None of the alternate refrigerants have been tested by Acura, and none have been approved for use in Acura vehicles.
2. If your use of them damages A/C components, your dealership is responsible for the repairs.
3. To prevent contamination of your R-12 and R-134a recovery-recharging equipment, you'd need to buy separate equipment.
4. A system converted to an alternate refrigerant has different charging valves to accept that refrigerant; you can't use any others.
5. Getting a consistent supply of an alternate refrigerant may not always be possible.
6. Some of the alternate refrigerants may be flammable. Flammable refrigerants should NEVER be used.

You can avoid these concerns (along with the R-12 scarcity factor) by converting the A/C system to R-134a. All Acuras can be converted WITHOUT replacing the compressor. All you need is an R-134a retrofit kit. For more information, refer to S/B 95-008 , "Converting R-12 A/C Systems to R-134a".
