PHOBOOS A/C Compressor for Honda Civic 2006-2011 L4 1.8L CO-4918AC — TRSE07, Prefilled PAG46, Direct Replacement

PHOBOOS A/C Compressor with clutch is a direct-replacement air conditioning compressor engineered to restore fast, quiet cooling to Honda Civic 2006–2011 L4 1.8L coupe and sedan models.

If your Civic is not cooling like it used to or the factory compressor has failed, this PHOBOOS CO-4918AC unit provides an OE-style swap with prefilled oil and a matched pulley for straightforward installation. Built as a TRSE07-type compressor, it is charged with PAG46 oil, designed for R‑134a refrigerant systems, and dimensioned to match factory mounting and electrical interfaces so you can get the vehicle back on the road quickly.

How does this compressor restore cooling performance?

The PHOBOOS compressor delivers efficient refrigerant compression to recover cabin cooling power, rated to support up to roughly 4000W of cooling under high ambient conditions. The internal components and pulley sizing optimize refrigerant flow and pressure for steady air-conditioning output.

• Type: TRSE07 compressor optimized for R‑134a systems.
• Prefilled oil: 120mL ±20mL of PAG46 for lubrication and compatibility.
• Pulley: 100mm diameter, 7-groove for correct belt engagement.
• Voltage: 12V electrical system compatibility.

Will this compressor fit my 2006–2011 Honda Civic L4 1.8L?

PHOBOOS designed this part to be a direct replacement for the listed Honda Civic years and engine type. Confirming fitment against the part numbers and images prevents mismatches, and the OE-matched mounting points allow for a bolt-on installation in matching vehicles.

• Compatible vehicle: Honda Civic 2006–2011, L4 1.8L, coupe and sedan.
• Cross-reference numbers included: CO 4918AC and many OEM equivalents.
• Compare product images and spec sheet with your original compressor before purchase.

How easy is installation and what does the warranty cover?

Installation is simplified by the OE-style form factor and prefilled PAG46 oil, avoiding initial oil top-up for many installations. The unit is built to bolt in where the original compressor sat; however, line fittings, electrical connectors, and system evacuation/charging should be handled by a qualified technician.

• OE-matched design for direct bolt-on replacement.
• Prefilled with PAG46 oil — saves initial setup steps.
• Professional evacuation and refrigerant recharge required after installation.
• Includes a 12-month unlimited-mileage warranty for parts confidence.

What are the technical specifics I should verify before buying?

Match these key measurements and specifications with your original compressor to ensure proper fit and performance. Differences in pulley grooves, diameter, oil type, or refrigerant compatibility can cause improper operation or premature failure.

• Pulley groove count: 7 grooves — confirm belt compatibility.
• Pulley diameter: 100 mm (3.94 inches) — check alignment and tension.
• Oil type and volume: PAG46, 120mL ±20mL prefilled.
• Refrigerant: R‑134a system compatibility and 12V electrical requirements.
