Detailed Description

Denso manufactures this A/C compressor as a factory-new unit based on the company’s original air conditioning system engineering. That background matters for service work because the compressor is built around the same fitment and performance requirements used by major vehicle manufacturers. The 471-1166 is listed for 1994-1997 Toyota Land Cruiser and 1996-1997 Lexus LX450 applications, making it a focused choice for restoring cabin cooling on these vehicles.

This part cross-references Four Seasons (e.g., 77393, 78393) for the same application.

What It Helps Address

• Weak or inconsistent A/C cooling output
• Compressor noise from worn internal components
• Loss of refrigerant system pressure
• Clutch engagement problems tied to compressor wear
• Service replacement needs on Toyota Land Cruiser and Lexus LX450 A/C systems

Installation Notes and Tips

Verify refrigerant type, pulley style, and mounting configuration before installation. Confirm system cleanliness, inspect related A/C components, and follow the vehicle service procedure for evacuation, oil balance, and recharge. This compressor is specified for R134A systems and V-belt applications, so matching the existing setup is important for proper operation.

Quality Assurance

Denso is a major OE supplier of A/C compressors, and this unit is manufactured and tested to OE-level standards for fit and performance. The 471-1166 is built as a new compressor rather than a remanufactured unit, supporting dependable service on the listed Lexus and Toyota applications.
