What's the 2015 GMC Yukon refrigerant capacity?

The 2015 GMC Yukon holds 2.25 lbs of R134a refrigerant in its AC system. If replacing after a large refrigerant leak, the manufacturer recommends re-lubricating the compressor witH3 ounces of polyalkaline glycol (PAG) as well. Signs the Yukon may be low on refrigerant include warm AC air from the cabin, compressor or cooling line leaks, and failure of the AC's clutch. Freon circulates through the HVAC through low and high pressure ports. It's converted from a gas to a liquid form to allow cooling in the cabin. Over time, a loss of Freon can occur as compressors age and/or develop leaks. Cost of re-charging the AC in the Yukon averages $100-$200 in materials and labor.
