Summarizing GM's A/C Service Recommendations

To summarize GM's A/C service recommendations

1. Service R12 vehicles with high quality new or recycled and tested R12.

2. Purchase R12 from a reliable supplier. Test R12 for purity prior to use. GM SPO has a supply of high quality R12 available. Dealers are requested to use only R12 supplied by SPO for warranty repairs. This high quality refrigerant will insure system performance and avoid the possibility of introducing contaminated material into the customer's A/C system.

3. Carefully test recovered R12 using the PureGuard monitor. On recovery equipment not protected by the PureGuard, always test the recovery cylinder prior to recharging a vehicle's A/C system.

4. Discuss the R12 to R134a retrofit option with owners of GM vehicles when A/C system repairs are required. Provide the owner with a copy of the pamphlet, "Converting Your Auto Air Conditioning System To Use The New Refrigerant."

5. Become familiar with retrofit procedures and exercise care in the handling of dissimilar refrigerants to prevent contamination.

6. Install the PureGuard 2 on your R134a refrigerant recovery cart and carefully test recovered R134a especially when servicing vehicles previously retrofit from R12.

7. Establish a regular procedure using PureGuard 2 for testing for high levels of air in your R12 and R134a recycled refrigerant reserves.
