What kind of refrigerant is in a Chevy S-10?

Answer 1

You can either look on the data plate on the compressor, or the vehicle owners manual. It really depends on year models allmost every vehicle produced after 1993 were r-134a refrigerant a/c systems, however prior to 1993 most were r-12 refrigerant a/c systems. Now some auto parts stores sell the do it yourself conversion kit, which converts the old r-12 cfc ( chlorine fluorine carbon) system to the r-134a hfc ( hydro fluorine carbon), this kit usually for GM vehicles includes a new filter dryer and new seals and gaskets which can tolerate the r-134a refrigerant. But you can have a pro mechanic do the work for you which runs around $500- $600 depending on quality. However other vehicles may need other things such as new compressor clutch to handle the higher pressure loads. I re-done my a/c on my Chevy S-10 with the diy kit, its fairly easy some kits may include the special tools and a instruction manual.
