ILONPA AC compressor with clutch for Nissan Altima 2.5L (2013–2018) S & SR base — single‑plug, R‑134a, PAG‑46 prefilled

Replacement ILONPA air-conditioning compressor with clutch for Nissan Altima 2.5L (2013–2018) S and SR base trims, equipped with a single electrical plug for direct fit.

This ILONPA compressor assembly restores cold-air performance by replacing the original AC compressor and clutch in compatible Altima models. It is engineered as a direct-fit aftermarket unit: VCS141C compressor type, prefilled with 160 ml PAG‑46 oil, designed for R‑134a refrigerant, and fitted with a six-groove pulley measuring 115 mm across. Verify your vehicle’s trim (S or SR base only) and electrical connector count (single plug) before purchase to avoid compatibility problems.

Will this compressor fit my Nissan Altima?

This unit fits Nissan Altima 2.5L model years 2013 through 2018 but is limited to the S and SR base trims. It is not compatible with SL or SV variants and is supplied with one electrical connector, so vehicles requiring two plugs will not match.

• Fits: Nissan Altima 2013–2018, 2.5L — S and SR base trims only
• Not compatible: SL and SV trims
• Connector: single-plug electrical connection (confirm under-hood wiring)
• Physical match: designed as a direct-replacement assembly

What technical specifications should I expect?

Key mechanical and fluid specs are provided so you can match the new compressor to your existing AC system. The unit uses standard R‑134a refrigerant and ships precharged with PAG‑46 oil to ensure proper lubrication and reliable startup.

• Compressor model: VCS141C
• Oil type and fill: PAG‑46, prefilled with 160 ml
• Refrigerant compatibility: R‑134a
• Pulley: 6 grooves, 115 mm diameter

What should I know about installation and performance?

The compressor is built from high-strength aluminum alloy and designed for quiet, efficient operation to help maintain cabin comfort without excessive vibrations. To protect the new unit and achieve long service life, the entire AC circuit must be cleaned and evacuated of any contaminants prior to installation.

Who is this for: This ILONPA compressor assembly is intended for technicians, DIY mechanics, and fleet managers replacing a failed or worn AC compressor on Nissan Altima 2.5L models from 2013–2018 in S or SR base trims. It is a practical aftermarket option when you need a direct-replacement unit with clear cross-reference part numbers, factory-style specifications (VCS141C, PAG‑46, 160 ml), and a single-plug electrical interface. If your Altima is an SL or SV trim, or your vehicle wiring requires two connectors, select a different compressor variant to ensure proper fitment and function.
