Denso 471-1241 A/C Compressor

Denso 471-1241 A/C Compressor Overview

The Denso 471-1241 is a factory-new A/C compressor built to OE standards for R12 systems. As an OE supplier to major vehicle manufacturers, Denso designs these compressors for accurate fitment, stable operation, and consistent air conditioning performance.

Compatible with select Toyota Corolla applications, including 1990-1992 Japan-built vehicles and 1993 Corolla models built to 8/93, this compressor is a direct-fit option for restoring cabin cooling performance.

Key Features

• Part number: 471-1241
• Refrigerant type: R12
• Clutch maximum diameter: 140.0 mm
• Serpentine belt pulley design
• Bolt tangent mounting type
• Factory-new compressor built to OE specifications
• Designed by the original OE supplier for the application

Detailed Description

Denso 471-1241 is an A/C compressor engineered for vehicles that originally used R12 refrigerant and a serpentine belt drive. The bolt tangent mounting style and OE-level construction support proper alignment and dependable compressor operation in the HVAC system. For Toyota Corolla owners, this part number is a focused replacement choice when restoring cooling performance on the listed model years.

This part cross-references Toyota (e.g., 88310-1A150, 883201A160) for the same application.

What This Compressor Helps Address

• Weak or inconsistent cabin cooling
• Noisy compressor operation from worn internal components
• Loss of refrigerant compression in an aging R12 system
• HVAC performance issues tied to compressor wear
• Fitment problems from using the wrong pulley or mounting style

Installation Notes and Tips

Verify refrigerant type, pulley configuration, and mounting style before installation. This compressor is specified for R12 systems, so the vehicle’s HVAC setup must match that requirement. Confirm the application against the Toyota Corolla fitment details for 1990-1992 Japan-built vehicles and 1993 models built to 8/93.

For best results, inspect the rest of the A/C system for contamination, leaks, and wear before replacing the compressor. Proper evacuation, charging, and system flushing procedures should be followed according to service specifications.

Quality Assurance

Denso manufactures this compressor to strict OE standards and tests it as a factory-new replacement part. Because Denso originally engineered these compressor designs, the 471-1241 reflects the brand’s OE application knowledge and fitment focus.
