How does this compressor match my vehicle's original equipment?

The unit is sized and specified to fit 2003–2008 Toyota Corolla and Matrix models with the 1.8L inline-4 engine. It uses the 10S15L compressor type, a six-groove 140 mm pulley, and the factory-standard PAG46 oil volume of 130 ml. That ensures dimensional fitment and functional compatibility with the vehicle's A/C system.

• Vehicle fit: 2003–2008 Toyota Corolla L4 1.8L and Toyota Matrix L4 1.8L
• Compressor type: 10S15L with 6 pulley grooves

Will installing this compressor improve cooling and reduce noise?

This ECCPP compressor is engineered for steady cooling performance and reduced vibration; factory testing aims to keep operating noise under 72 dB. With correct installation and a leak-free A/C circuit, cabin temperatures can reach lower setpoints and run more quietly than a worn or failing compressor.

• Noise target: tested under industry benchmarks, typically below 72 dB
• Durability: cast aluminum housing for lower vibration and long-term strength
• Pre-test: nitrogen pressure checks to verify sealing and leak resistance
• Pre-lubricated: avoids incorrect initial oil fill that can harm the unit

What comes in the box and what should a mechanic expect during installation?

The package contains the air conditioning compressor and the clutch assembly; internal components are lubricated and the unit is pressure tested. Technicians should verify system cleanliness, replace the receiver/drier or accumulator as recommended, and ensure correct oil charge and refrigerant type before startup.

• Included: complete AC compressor assembly plus clutch
