Original agency Altima compressor, used for only one week. Altima radiator, Chinese, used for only one week. Both come with a one-year warranty. I bought the compressor and radiator and discovered that the problem I had was not caused by the radiator or compressor. They have no defects, and you have the right to inspect them. All their invoices are available. Model: 2021, and I believe it fits from 2019 to 2026. As for earlier models, I honestly don't know.
