The amount of oil in the compressor is dependent on the specific compressor model installed in that particular vehicle. This varies based on the manufacturer and the compressor's size and design.
To find out the correct amount:
1. Identify your compressor: Find the compressor's model number (usually stamped on the compressor itself).
2. Consult a repair manual: A repair manual specific to your 2005 Chevy Equinox will provide the correct oil type and quantity for your particular compressor. These manuals are available online or from auto parts stores.
3. Contact a qualified AC technician: An experienced auto AC technician can determine the correct oil capacity based on the compressor model they find in your vehicle. This is the most reliable method.
Never attempt to add oil to your AC system without knowing the precise amount and type required. Doing so can severely damage the system.
