Signs of a Car AC Compressor Leaking Oil
Now that you’ve fixed the problem, let’s reveal the signs that indicate that your car’s AC compressor is leaking oil. This knowledge will help you tackle the problem faster in the future.
Visible Oil Puddles: If you notice any puddle or oil spot under your car, especially in the area beneath the AC compressor, this is a significant indicator of a leak. The oil has a distinctive color, usually a bright green, which is a result of the dye added to the refrigerant oil to help identify leaks.
Decreased AC Performance: A compressor leaking oil will gradually lead to deteriorated performance of the AC system. The car may take longer to cool down, or the air blown might not be as cold as it should be. It occurs because the AC compressor is unable to circulate the refrigerant effectively due to the reduced oil level.
Foul Smell: Oil leaks can cause a foul odor to emit from the AC vents, resembling a musty or burnt smell. It is created due to oil mixing with refrigerant and other substances, producing an unpleasant odor that can be noticeable when you turn on the AC.
