SCITOO AC Compressor for Acura TSX 2.4L (2009–2014) is a direct-fit air conditioning compressor assembly with clutch designed to restore cold, quiet A/C performance in compatible TSX models.

If your Acura TSX from 2009–2014 is blowing warm air or the compressor clutch is worn, this SCITOO compressor is built as a one-to-one replacement that matches OE fitment and connections. Constructed from aluminum alloy with an HS090L compressor design, a 7-groove pulley and prefilled PAG46 oil, it aims to simplify installation and reduce downtime so you can get your cabin cooling again.

How will this compressor improve my car’s cooling?

The SCITOO unit restores the core mechanical component that circulates refrigerant, allowing your system to produce colder air quickly. It’s engineered to reach working temperatures fast and operates at low audible levels for a comfortable cabin.

• Compressor type: HS090L for efficient refrigerant flow
• Pulley: 7 grooves, 4.53" diameter for direct belt alignment
• Comes prefilled with 150±10 ml PAG46 oil—no oil top-up needed on first install
• Designed for R134a refrigerant; recommended 70–80% charge on installation

Will this part bolt into my 2009–2014 Acura TSX without modifications?

This SCITOO compressor is offered as a direct replacement for the TSX 2.4L models listed; it mirrors OE mounting points, pulley grooves and electrical connector types. Still, verify your vehicle’s pulley groove count, part number and refrigerant type before ordering to ensure compatibility.

• Fitment range: Acura TSX 2.4L, model years 2009–2014
• OE cross-references include 38810-RL5-A02 and related numbers listed by manufacturers
• Includes clutch assembly—reduces need to transfer old clutch
• Compare photos and vehicle details prior to installation

What should I know about installation and maintenance?

Installers should purge and flush the A/C lines and receiver-drier before fitting the new compressor to prevent contamination. The compressor ships with internal oil, but you must evacuate and refill the system with the correct refrigerant charge after installation to achieve proper cooling.

• Item contains oil on delivery—no initial oil addition required
• Add R134a refrigerant to 70–80% of system capacity (do not overfill)
• Clean the cooling-system pipes; remove debris and metal shavings first
• Recommended professional A/C service for vacuuming and leak-checking

How quiet and durable is this compressor during normal driving?

SCITOO designed this compressor for low vibration and reduced noise, rated to operate at or below approximately 72 dB under normal conditions. Using quality materials like an aluminum alloy housing and modern clutch design, it aims to deliver consistent performance when the rest of the A/C system is in good condition.

• Noise level: engineered ≤72 dB for quieter cabin comfort
• Material: corrosion-resistant aluminum alloy housing
• Internal oil: factory-filled 150±10 ml PAG46 for lubrication
• Clutch included to ensure proper engagement with original belt system

Who is this for: This SCITOO AC compressor is intended for owners and mechanics replacing a failing or noisy A/C compressor on Acura TSX 2.4L vehicles from 2009 through 2014. It’s a practical choice when you need OE-style fitment, prefilled internal oil, and a clutch-equipped assembly; however, it requires proper system flushing and recharging with R134a by a qualified technician.
