Nissens 891548 A/C Compressor

Overview

The Nissens 891548 A/C compressor is built to OE standards for reliable air conditioning performance under demanding operating conditions. It uses an SD7H15 compressor design with a clutch included, and it is configured for R134A systems with PAG 100 oil.

Fits 2005-2006 Mercedes-Benz FS65, N/A. Part number 891548 is a direct reference for this application, and 891548 is also cross-referenced to common aftermarket numbers for the same compressor fitment.

Key Features

• OE-standard compressor construction for consistent A/C operation
• SD7H15 compressor type with serpentine belt drive
• Clutch included for a complete compressor assembly
• Configured for R134A refrigerant and PAG 100 oil
• 2-pin electrical connector and 12-volt operation
• Includes O-rings for sealing at the connection points

Product Details

Nissens engineered this compressor around the pulley, clutch, hub, bearing, and wobble plate to improve pumping efficiency while reducing noise and vibration. That design focus supports stable performance in high-stress HVAC use, making the Nissens 891548 a practical replacement for Mercedes-Benz FS65 air conditioning service. The 2A pulley groove setup and serpentine belt compatibility help match the original system layout, while the pre-filled oil specification and included clutch simplify parts selection for the correct refrigerant setup.

This part cross-references UAC (e.g., CO4626, CO4626C) for the same application.

Common Issues It Can Address

• Weak or inconsistent cabin cooling
• Noisy compressor operation
• Excessive A/C vibration during operation
• Compressor seizure or internal wear
• Loss of refrigerant system pressure from compressor-related sealing issues

Installation Notes

Verify refrigerant type, oil specification, connector style, and pulley configuration before installation. This compressor is listed with shipping oil only for the referenced Mercedes-Benz FS65 fitment, so the oil must be drained and refilled to the correct specification during service. Replace the O-rings at the connections and evacuate and recharge the system according to factory procedures.

Quality Assurance

Nissens manufactures compressors to OE standards and tests them for performance under high-load conditions. The 891548 part number identifies this compressor for the listed application and helps confirm the correct replacement during HVAC repair.
