ILONPA AC Compressor with Clutch for Honda Civic 2002-2005 1.7L — TRSA09 Core, Prefilled PAG 100 Oil

ILONPA's new air conditioning compressor with clutch replaces the factory unit for 2002–2005 Honda Civic models equipped with the 1.7L engine, delivering reliable cooling performance and easy drop-in fitment when installed correctly.

This aftermarket compressor is engineered to match the original equipment geometry and mounting points for Civic L4 1.7L engines (2002–2005) while using a TRSA09 compressor core and prefilled PAG 100 oil. It replaces many common part numbers, so it’s a practical option when restoring AC function after compressor failure. Note: this unit is strictly for 1.7L engines and is not compatible with 2.0L Civics.

Will this compressor fit my Civic 1.7L from 2002–2005?

Yes — the unit is designed to align with OEM mounting and belt configurations used on 2002–2005 Civic models powered by the 1.7L L4 engine. Compatibility excludes 2.0L engines, so verify your engine displacement before purchase.

• Fits 2002, 2003, 2004, 2005 Honda Civic with 1.7L engine only
• Replaces numerous OEM and aftermarket part numbers listed in the product features
• Mounting points and pulley match factory specifications for the 1.7L application

What are the technical specifications I should know?

The compressor uses a TRSA09 core with a six-groove pulley and 109 mm pulley diameter to mirror factory operation. It arrives prefilled with approximately 120±10 ml of PAG 100 oil and includes a clutch assembly for straightforward installation.

• Compressor Type: TRSA09
• Oil Type: PAG 100, prefilled 120±10 ml
• Pulley groove count: 6; pulley diameter: 109 mm
• Includes clutch compatible with Civic 1.7L belt drive

How does this compressor perform and what materials are used?

The ILONPA compressor is made from high-strength aluminum alloy for durability and thermal stability. It’s designed to keep operational noise and vibration low while helping maintain fuel efficiency during steady driving by reducing extra load on the engine.

• Aluminum alloy housing for reduced weight and corrosion resistance
• Engineered to minimize noise and vibration
• Built to withstand repeated cycling and typical highway use

What should I do before and during installation?

Proper preparation improves longevity: flush and clean the AC system thoroughly, remove any residual contaminants, and confirm evaporator and lines are dry of cleaning agents before fitting the new compressor. Professional installation and vacuuming/charging with the correct refrigerant and oil volume is recommended to ensure correct operation.

• Thoroughly clean the A/C system and evaporate cleaning agents completely
• Confirm compatibility with 1.7L engine prior to installation
• Have a qualified technician perform vacuum, leak check, and refrigerant charge

Who this is for: If you own a 2002–2005 Honda Civic with the 1.7L engine and need a direct-fit replacement compressor and clutch assembly that mirrors factory specifications, this ILONPA unit is intended for you. It’s suited to DIYers with mechanical experience and to professional technicians restoring air conditioning performance. Do not purchase if your Civic uses a 2.0L engine — consult vehicle build information or a service manual to confirm engine displacement before ordering.
