Where do I put PAG oil in a new AC compressor?
Pour the oil very slowly into the intake port or low side of the compressor. This is where the large line entered. While pouring in the refrigerant oil, rotate the hub and clutch slowly to let the oil enter the compressor.
How do I know when my AC needs oil?
One of the earliest signs that the AC compressor is operating with an insufficient oil amount is the emergence of humming noises from your air-conditioning system. At the same time, you may notice that the compressor has suddenly become hard to start.
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.
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.
How much oil is in a new compressor?
The goal is to maintain the new OEM amount of oil. 3 ounces of oil (grey area) Old New 3 ounces In this example the removed compressor contains 3 ounces so the new compressor should have 3 ounces as well. This way we maintain the original 10 ounce oil charge consistent with the new system.
Is it OK to add extra oil to air conditioner?
It’s typically ok for an extra ounce or two of oil to remain in the system, provided it is contaminant free. A significant overcharge of oil (over 2 ounces) however, can cause multiple problems, including inefficient cooling and immediate or premature compressor failure.
