What It Helps Solve

• Weak or inconsistent cabin cooling
• Noisy compressor operation
• Excess vibration from worn internal components
• Loss of refrigerant circulation in an R134A system
• Compressor failure on select Lexus GS430 and Lexus SC430 applications

Installation Notes

Verify refrigerant type, oil specification, connector pin count, and pulley configuration before installation. This compressor is oil-filled and uses PAG 46, so the system should be drained and refilled according to service requirements. Fitment notes state that the compressor is filled with shipping oil only and must be drained and refilled before use.
