I read somewhere that you should not mix R134a with R12. Also, the colour of the cap on the recharge valves indicates which coolant is in the system. Does anyone know if this is for real, and a serous issue.
I am also experiencing a lack of cold air, but have been reluctant to pick up one of these recharge kits because I think I have R12 in the system (I have a black cap instead of a green one). Could someone shed some light on this for me.
Thanks.
