it cools about as good as with r12
An R12 system must be retrofitted to be made compatible with R-134a.
Its 134a it says it right under the hood.
R12 134A pre 1996 is r12, after is r134
r12 or 134a
92 was originally R12. But it can easily be converted to 134A.
if it has 134a hose connections, then it takes 134a. if it has the regular thread couplers then it should still have r12 in the system
R12 And if you still have this change over to 134a instead of buy r12
try using the 134A it's supposed to be compatiable with your r12 that's what i had to do!
No. R12 systems are designed for R12. The lubricating oil for 134a is synthetic and will attack the o-rings in a R12 system. I think the operating pressures are also different.Samething is now happening to residential ACs. R22 is out and 410 is in.They are not compatible.SOL
If you mix r12 with r134 air conditioning system, it will cause a high pressure in your airconditioning system and eventually damage the compressor and the evaporator. R12 is only for r12 aircon and something with r134, it can't be mix.
YOU don't! If your system is R12 (freon)it should ONLY be serviced by a professional. The way to determine is if you have quick-couple service fittings, it is 134A (not freon) equipped, if it has threaded service fittings, it is R12 (freon) equipped. When you take the vehicle to a professional, he will convert your R12 system (if it is so equipped) to 134A. R12 (freon) has not been manufactured since 1995 by law (Montreal Accord) and it is VERY hard to find. A license is required to purchase R12 and it may not be legal to sell in your state. Mark---Raleigh, NC Actually Freon is a registered trade name or trademark for E. I. DuPont. It is not strictly R-12. R-134a is commonly called Freon.
134a replaced R12 about 1995.
