SCITOO AC Compressor with Clutch for Chevrolet S10 2.2L (1998–2003) — V7 Aluminum, 6-Groove Pulley, Prefilled Oil

SCITOO AC Compressor with Clutch is a direct-fit air conditioning compressor designed to restore reliable, quiet cooling for Chevrolet S10 2.2L models from 1998–2003.

If your S10’s air conditioning blows warm air or the compressor has failed, this SCITOO replacement unit is built to match OE mounting points and performance while arriving prefilled with 130 ml of PAG 46 oil. The aluminum-alloy V7 compressor includes a 6-groove pulley and a clutch assembly so installation replaces both rotating and engagement components at once. It fits multiple GM and related compact truck applications, and comes with a list of cross-reference numbers for confirmation.

Will this compressor physically fit my vehicle and replace my old unit?

The compressor is marketed to fit Chevrolet S10 2.2L (1998–2003) and several related models like Sonoma and LUV with compatible engine sizes. Match the mounting holes, electrical connector and pulley grooves against your current compressor before ordering to ensure a proper swap.

• Compatibility: Chevrolet S10 2.2L 1998–2003, Silverado-related LUV models, GMC S15/Sonoma and Isuzu Hombre variants where listed.
• OE cross-references: includes numbers such as 1137024, 1520446, DW67291, 10306420 for confirmation.
• Physical features: V7 compressor, aluminum alloy body, 6-groove pulley, clutch included.

How does the compressor perform in real-world driving and noise levels?

This unit is engineered for fast cabin cooling and relatively low operational noise. SCITOO specifies near-instant cooling response and noise at or below 72 dB under normal conditions, reducing cabin temperature quickly while keeping vibration and sound minimal.

• Cooling: Designed for rapid temperature drop shortly after engagement.
• Noise: Engineered to operate ≤72 dB for quieter cabin comfort.
• Vibration control: Balanced pulley and clutch assembly reduce vibrations during use.

What installation and system-prep steps should I follow?

The compressor is shipped prefilled with 130 ml PAG 46 oil, so no initial oil top-up is required; however, the refrigerant must be added to the system to 70–80% capacity during recharge. Before installing, thoroughly flush the A/C lines and receiver/drier to remove debris or metal shavings that could damage the new compressor.

• Prefilled oil: 130 ml PAG 46 included in the unit on delivery.
• Refrigerant: Add refrigerant to approximately 70–80% of system capacity when recharging.
• System prep: Clean cooling pipes and remove contaminants to avoid premature failure.

Which parts and specs are included with the compressor?

The assembly arrives as a complete compressor with clutch and specified pulley configuration. Materials and part numbers are listed for easy verification against the old unit before purchase.

• Included: Compressor with clutch assembly and pulley (6 grooves).
• Material: Durable aluminum alloy housing for heat dissipation and corrosion resistance.
• Reference numbers: 89018955, 620446, 67291 and other cross-references to aid matching.

Who this is for: This SCITOO compressor suits DIY mechanics and professional technicians replacing a failed or noisy A/C compressor on late-1990s and early-2000s compact GM trucks (notably Chevrolet S10 2.2L). It’s intended for those who need an OE-style physical fit, a pre-oiled unit to speed installation, and clear cross-references for parts matching. If you’re unsure about compatibility, compare mounting points, electrical connectors and pulley grooves to your existing compressor or consult a qualified installer before purchase.
