You have to have a permit to buy R12 and it is very expensive. Any system that uses R12 can use 134 the replacement for R12. You will need adapters that screw onto the old fittings that accept the hose that hooks to the 134 can. You add freon to the low side of the system. The adapter are different sizes so you cannot put it in the high pressure side. Yes, if you have any mechanical knowledge at all, you should be able to charge the system without much trouble.
OR you can buy all the R12 you like for cheap from Mexican sources and keep the longevity of your original equipment and lower operating pressures of R12. They way your system was designed. R12 comes in everyday by the truckload thanks to our new open border laws.
== == Was built with r12, can be converted to r134a.
R12-if it has ac of course.
easily. Buy a converter from local parts store for r12 to r134 system should cost 6-10 dollars. Screw converter onto AC fittings and charge as a normal system Freon is about the same cost.
Only if you're trying to destroy your AC system. Never mix refrigerants.
Most likely 134a not true, factory ac is r12.
Check charge. (R12)
No, the 1994 Mercury Sable does not use R12 for recharging the A/C unit. The 1994 Mercury Sable uses R134a Freon.
2.87 lb of R12 that spec is from the owners manual
freon R134A - MAY NEED RETROFITTING (LINE ADAPTERS FROM R12 TO R134A) MOST COST ABOUT $15.00. COMPLETE CHARGE SHOULD COST ABOUT $145.00.
First off, it does not use Freon (R12) it uses R134a or a similar product. Second, if it is low of refrigrant it has a leak that needs repairing. Take it to a professional. You cannot repair the leak and do not have the proper tools to charge the system properly.
It should tell you on the air conditioning unit but it's more than likely R12. I have an '89 Caprice and it takes R12.
Would have been built for R12, can be converted to R134a.
