Folks, I own a 2011 Avalon in good condition with around 170,000 miles on it. During a recent 4-hour trip from NY, I noticed a chattering noise at high RPMs. Upon arriving home, I investigated the issue and, while revving the engine, heard a pop, a squeal, and detected a burning smell. Further inspection revealed that the AC had stopped working. After conducting some basic tests, it became apparent that there was no refrigerant left in the system. Using nitrogen, I pressurized the system and discovered a refrigerant leak between the AC compressor and its pulley. It seems like I'll need to replace the compressor. I have experience with HVAC work and possess the necessary equipment like a vacuum pump and gauges.
I'm currently researching what components require replacement apart from the compressor. Is it essential to replace the drier/TXV, etc.? I came across information suggesting that these vehicles might have a microchannel condenser, which would necessitate replacing the entire condenser when replacing the compressor. Another concern is the quantity of oil required after swapping both the condenser and compressor. Some sources suggest pouring out the old oil and refilling the new compressor with the exact amount. What's the recommended approach when replacing the condenser too? Has anyone here replaced their compressor before? Additionally, I'm puzzled by the factor charge. Normally, this information is on a label under the hood, but I found a Min/Max range, with a maximum of 1.21lbs indicated, almost like it's a variable range. Any insights or experiences would be greatly appreciated.
