Answers :

Follow the biggest a/c line from start to finish.Usually the a/c port is located near the firewall.I have seen the port located under the passenger wheel well.There should be a decal that states the type freon on or near the fan shroud,core support or on the under side of the hood.It is most likely to be type r-12.You can purchase an r-134a conversion kit. If you are not a/c certified to use r-12,you do not need certification for r-134a.
