Detailed Description

Nissens 891613 is an A/C compressor for Porsche 911 fitments that require an R134A system with PAG 46 oil. The compressor uses a 10P15C design and includes the clutch, making it a focused replacement for restoring refrigerant circulation in the HVAC system. This part number, 891613, is also cross-referenced to 4710124, 93012602100, 93012602101, and CO11196ZI for the same application.

For Porsche 911 owners addressing weak cooling, compressor noise, or inconsistent A/C output, this compressor provides the core pumping component needed to restore system operation. The Nissens 891613 is built around components selected to control noise and vibration while maintaining pumping efficiency.

What It Is Used For

• Restoring refrigerant compression in a failing A/C system.
• Replacing a noisy or worn compressor assembly.
• Addressing poor cabin cooling performance.
• Correcting clutch-related compressor engagement issues.
• Supporting service work on R134A-based HVAC systems.

Installation Notes and Tips

Verify refrigerant type, oil specification, pulley configuration, and connector style before installation. This application notes that the compressor is filled with shipping oil only and must be drained and refilled to the correct specification during service. Confirm system cleanliness and replace the specified O-rings during installation.

Quality Assurance

Nissens manufactures compressors to OE standards and tests them for high-stress operation. The design focus on the pulley, clutch, hub, bearing, and wobble plate supports durable performance in the listed Porsche 911 application. Part number 891613 is built to meet the requirements of the specified fitment.
