There is no replacement product, upgrade product, for R-134.
News reports have said that in 2013 GM will start using HFO-1234yf.
No, there is retrofitting required.
It's only Freon if it was manufactured by DuPont, but to the important things... Your 89 would have had an R12 system from the factory. You can't use R134a in an R12 system unless you do at least a partial retrofit (evacuate all the R12 and compressor oil, replace the orifice tube, replace the accumulator, replace the hose connections, add PAG oil and R134a).
No, you cannot directly replace R404A with R134A, as they have different properties and applications. R404A is a blend designed for low-temperature refrigeration, while R134A is typically used in medium-temperature applications, such as automotive air conditioning. Using R134A in a system designed for R404A could lead to inefficiency, inadequate cooling, and potential damage to the system. Always consult with a professional technician before making refrigerant changes.
An R12 system must be retrofitted to be made compatible with R-134a.
No, R134b and R134a are not the same refrigerant, and R134b is not a direct drop-in replacement for R134a. While both are similar in terms of their chemical structure, they have different properties and performance characteristics. Using R134b in a system designed for R134a may lead to inefficiencies or damage. Always consult the manufacturer's specifications before making any refrigerant substitutions.
No. It is illegal, will not work properly and R12 Freon is not available for the public to buy anyway.
R134a is a refrigerant gas
Can you mix r134a with r410a?
No, unless the a/c has been converted to r134a
R134a.
Chevy switched from R12 to R134a for the model year 1994. Your truck should be R134a.
newer vehicles, such as a 99 jeep, all use 134-A refrigerant.
