What type of freon do old cars use?
All classic car original air conditioning systems were filled with dichlorodifluoromethane or R-12/CFC-12 Freon. Even newer cars used the standard R-12 until the EPA, under section 609, in an attempt to reduce atmospheric ozone depletion, mandated that manufacturers phase out its use by the end of the 1994 model year.
What year cars use R12 refrigerant?
By international agreement in 1987 (the Montreal Protocol), the use and production of CFCs such as R12 began to be phased out, with automobile manufacturers required to stop using it by the end of the 1994 model year.
What year did vehicles switch to 134a?
1994
R-134a first began to see widespread usage in 1992 and took over the automotive market entirely in 1994. If you have a vehicle from 1994 or newer your air conditioning unit takes R-134a. It has been the standard automotive refrigerant for over twenty years.
Can you mix R12 and 134a?
As previously stated, R12 systems usually use mineral oil, which is incompatible with R134a. When R134a comes into contact with mineral oil, it can hinder the oil from returning to the compressor, or possibly reduce heat transfer.
What is difference between R134 and R134a?
R134 and R134a have same chemical formula and atomic weight but different chemical structures. R134 has NBP of about -19 C whereas R134a has a NBP of about -26C. And dont use capital ‘A’ in R134a …. “A” denotes that the refrigerant is non -azeotropic.
What kind of Freon does a Toyota Tacoma use?
There are two types of freon, or refrigerant, that can be used in a Toyota Tacoma, but which one depends on the vehicle’s model year. R12 freon typically is used for vehicles manufactured before 1984, and it is not an environmentally friendly gas. Cars of more recent manufacture use R134a.
How to add Freon to a 1995 Toyota pickup?
How to add freon to your 1995 Toyota Pickup: hook up the can of refrigerant (likely r-134a) to the low pressure port. When your compressor kicks on, add freon to the correct pressure. In addition to cooling, freon lubricates the compressor when it runs.
How much refrigerant is in a Toyota?

Can you put Freon in a Toyota R-134a?
Fit the Freon recharging kit’s coupler onto the service port. However, do not turn the valve atop the kit. If the coupler does not fit the service port, then you have the wrong recharging kit. An R-12 kit will not fit an R-134a system and vice-versa. Set the kit down, but ensure it is nowhere near movable engine parts.
