Retrofit Requirements
The customer should be reminded that there is NO requirement in the U.S. to retrofit any vehicle produced with R-12. Vehicles built with R-12 can be
serviced with R-12 as long as it is available (except in certain Canadian Provinces). GM has taken steps to extend the supply of R-12 and recommends
that all R-12 vehicles continue to be serviced with R-12 as long as it is available.
Training Video
Before doing a retrofit the first time, it is recommended that you view the Certified Plus Training Video, Program number 51010.15, "R-134a Retrofit
for GM Cars and Trucks".
