What kind of oil do I put in my AC compressor?
Most 1996 and newer A/C systems use R134a refrigerant and require some type of PAG (polyalkylene glycol) oil for the compressor. If the wrong type of compressor oil or the wrong viscosity compressor oil is used, it may damage the compressor.
What kind of oil does an air conditioner compressor use?
Automotive air conditioning compressors require specific types of lubricants. Most 1996 and newer A/C systems use R134a refrigerant and require some type of PAG (polyalkylene glycol) oilfor the compressor. If the wrong type of compressor oil or the wrong viscosity compressor oil is used, it may damage the compressor.
How much Oil can I put in my compressor?
Otherwise, the system could be overcharged from refilling with too much compressor oil or UV leak dye during A/C service. 3 to 5cc of UV leak dye is tolerated for systems up to 1000 gram of refrigerant! Oil distribution within the A/C system (reference values, varying depending on outside temperature and engine load)
What kind of oil do you use for a R-1234yf compressor?
Newer vehicles with R-1234yf A/C systems require a special 1234yf compressor oil specified by the vehicle manufacturer. General Motors recommends GM lubricants only (PAG-PSD1 #19260643 for 2013/14 Cadillac XTS, and PAG-ND12 #19299051 for 2013 Cadillac ATS).
How to drain and add refrigerant oil to an AC compressor?
Most people recommend to take all the oil out from the oil compressor, and fill the new one with the same amount, since we opened the system, replaced the expansion valve and dryer, we decided to use the low amount of oil recommended for this compressor. Use the drain side, or low side to fill the new compressor with oil.
What kind of oil should I use for an A / C compressor?
“Universal” A/C compressor oils are often PAO-based and are not the same viscosity as the PAG oil recommended for a specific type of compressor. This can lead to poor lubrication and premature compressor failure.
Newer vehicles with R-1234yf A/C systems require a special 1234yf compressor oil specified by the vehicle manufacturer. General Motors recommends GM lubricants only (PAG-PSD1 #19260643 for 2013/14 Cadillac XTS, and PAG-ND12 #19299051 for 2013 Cadillac ATS).
Can you use mineral Oi L in an A / C compressor?
Mineral oi l should only be used in older R-12 A/C compressors because R-12 will not mix with R-134 refrigerant. “Universal” A/C compressor oils are often PAO-based and are not the same viscosity as the PAG oil recommended for a specific type of compressor.
Do you have to use PAG oil for an A / C compressor?
“Universal” A/C compressor oilsare often PAO-based and are not the same viscosity as the PAG oil recommended for a specific type of compressor. This can lead to poor lubrication and premature compressor failure. Newer vehicles with R-1234yf A/C systems require a special 1234yf compressor oilspecified by the vehicle manufacturer.
