87 elcamino v6 4.3 t.b.i.
I have 87 elk with v6 all stock/orig. Tired of Not being able to use car when it's hot outside! So I want to fix my a.c. but don't know where to even start. .lucky that all my components are intact/orig. I know the system has No pressure,but little else. When I discuss with other g.m. classics owners,I get mixed advice. Some say just get it converted at shop,its not worth headache. Others say keep original,do it yourself,or take to shop,but still keep original,as its easier/cheaper to stay with r-12. And that the hardest part is finding someone who is familiar with r-12,and finding the r-12 itself . so I recently had the opportunity to buy some r-12 cheap, thanks to old member retiring from the scene. And his advice was stay r-12 as the conversion req everything except evap to be changed. (Even hoses as 134-a leaks due to being smaller atoms) . So where do I start to determine r-12 or conversion? How can I tell if it has r-12 or 134 in it now? How do I test comp? Ive turned on a.c. but comp doesent seem to engage,guess I will have to learn the circuit and test. I read other forums about this subject ,but they are always incomplete. Any advice /personal experience\ or threads to follow appreciated.
