What are the OEM part numbers replaced by this AC Compressor?

The Honda Civic Compressor replaces the OEM part number 38800RNAA01. This specific part number identifies the compressor unit used by the manufacturer for the 1.8L engine models produced between 2006 and 2011.

The Honda Civic Compressor w/Clutch is the core component of the air conditioning system, responsible for compressing and circulating the refrigerant to keep the cabin cool. We chose this unit for our comparison because it includes the pulley and clutch assembly, which are necessary to engage the system and avoid the need for additional hardware purchases. Because the compressor is the heart of the cooling cycle, ensuring the part number matches your specific 1.8L engine is vital; a mismatch in the compressor shape or mounting points can prevent the unit from seating correctly. While this part number covers the compressor, you should confirm with the manufacturer if it includes the internal valve configuration for your specific region’s AC block, as regional manufacturing variations can occasionally cause bracket mismatches.

What to Check Before Buying the Honda Civic Compressor

Before ordering this replacement part, you must verify several technical details to ensure a correct fit for your vehicle’s cooling system.

• Confirm that your vehicle’s 1.8L engine matches the 2006–2011 production years for this specific part number.
• Verify that the pulley and clutch assembly included in this unit match the shaft diameter of your existing pulley.
• Check your owner’s manual to confirm the specific refrigerant type and pressure limits your system is rated for to avoid seal failure.
• Consult a qualified installer to confirm if your regional AC block requires specific mounting bracket adjustments.
• Ensure the pulley alignment is checked during installation to prevent bearing noise or belt slippage.

Choosing the Right AC Compressor for Your Vehicle

An AC compressor is the pump-like component that moves refrigerant through your car’s cooling lines to generate cold air. The Honda Civic Compressor sits as a standard replacement option for owners seeking to restore functionality to a failing system. If you require a specialized high-pressure unit or a specific aftermarket brand like R&Y or ECCPP for a different engine configuration, you may want to look at broader aftermarket options. However, for those seeking a direct replacement for the 38800RNAA01 standard, this unit provides the necessary components for a standard restoration.

To confirm fitment, see if the Honda Civic AC Compressor fits 2006-2011 1.8L models.

If you own a 2006–2011 Honda Civic with a 1.8L engine and need a replacement that includes the clutch and pulley, you should choose this compressor.
