Agree with goodguy if it aint been switched over already, not a big job just need a retro. kit. Came with R12, 1996 before Ford, GM and Chry. 'HAD' to change per EPA but some Chyr. Vehicles did it in 1994. Only reason I know had to take the cert. test to be able to purchase the R12 back then. What a rip off, cost 70.00 at that time, few years later think it was free and online! Somebody made some $! Now if for 'some' reason, i guess i can still purchase R12. What a deal.
