Will this compressor fit my 2004–2008 Acura TSX?

Yes — the SCITOO HS110 compressor is made to match Acura TSX 2.4L model years 2004, 2005, 2006, 2007 and 2008. Confirm fit by comparing OEM part numbers or visually matching the mounting pattern and electrical connector before purchasing.

• Compatible with OEM references such as 38810RBBA01 and many cross-reference numbers listed.
• Direct-fit mounting and pulley alignment to match factory brackets.
• Includes clutch assembly so you don’t need extra parts for replacement.

How is the compressor prepped for installation?

The compressor ships prefilled with 130 ml of PAG46 oil, so you won’t need to add oil for initial startup. Refrigerant is not included, so the system must be evacuated and recharged to 70–80% of capacity per vehicle specifications after installation.

• Precharged with 130 ml PAG46 oil for proper lubrication at first use.
• Clutch and pulley installed, pulley diameter 112 mm with 7 grooves.
• Final refrigerant charge and system evacuation still required by installer.

What performance and durability features does it offer?

Constructed from aluminum alloy and engineered as an HS110 compressor type, this unit aims to deliver strong compression while minimizing noise and vibration. Efficient operation helps the HVAC system reach cooler cabin temperatures quickly and maintain steady performance under typical driving conditions.

• Aluminum alloy body for lighter weight and corrosion resistance.
• Designed for low noise and reduced vibration during operation.
• Pulley: 7 grooves, 112 mm diameter to match serpentine belt systems.

Any installation tips or cautions I should know?

Before installing, thoroughly clean the vehicle’s A/C lines and receiver/drier to remove debris and metal shavings that could damage the new compressor. Compare photos and part numbers to ensure match, and have a professional perform evacuation and recharge for safe, reliable results.

• Flush A/C pipes and replace the receiver/drier if contaminated.
• Verify electrical connector and mounting points match your vehicle.
• Have a certified technician evacuate and recharge refrigerant to proper levels.

Who is this for? Technically minded DIYers and professional technicians working on 2004–2008 Acura TSX 2.4L vehicles who need a full replacement compressor with clutch. It’s suitable when the OEM compressor fails, leaks, or seizes — provided you verify fitment, clear contaminant from the system, and complete a proper refrigerant service after installation. The SCITOO unit aims to offer a cost-effective, ready-to-install alternative to OE replacement while providing the core specifications required for reliable A/C performance.
