Tackle a full air-conditioning repair in one box with the Four Seasons A/C Compressor Kit 4634NK, a complete package assembled to cover a compressor replacement on the 2007-2012 Nissan Sentra (All engines). Rather than sourcing pieces separately, this kit gathers the compressor and the related service components so the system can be serviced together.
- Complete kit contents: includes a new compressor, accumulator or filter drier, expansion device, compressor oil, and the necessary gaskets and O-rings.
- Refrigerant: configured for R134a systems.
- Pulley: 6-groove pulley with a 4.500 in outside pulley diameter.
- Four Seasons build: assembled and shipped as one package and put together to satisfy the compressor's warranty requirements, backed by decades of mobile A/C experience.
Because a failed compressor can circulate debris, replacing the drier and expansion device alongside the compressor is standard practice and is part of meeting the compressor warranty. If a worn or seized A/C compressor is the cause of your no-cold-air condition, this kit supplies the major components to address it.
