Detailed Description

Nissens part number 891590 is an A/C compressor designed for BMW 318i, BMW 318is, BMW 318ti, and BMW Z3 models within the listed fitment range. The compressor uses an SS96D1 type design and focuses on stable pumping performance, low noise, and reduced vibration through attention to critical internal components such as the pulley, clutch, hub, bearing, and wobble plate. This makes it a practical OE-style replacement for restoring cabin cooling performance on 1992-1999 BMW 318i, 1992-1999 BMW 318is, 1995-1999 BMW 318ti, and 1996-1998 BMW Z3 applications.

This part cross-references UAC CO10174C for the same application.

What It Helps Fix

• Weak or inconsistent cabin cooling
• Compressor noise, vibration, or pulley-related wear
• A/C system failure caused by compressor seizure or internal damage
• Loss of refrigerant circulation in R134A systems
• Clutch engagement problems on the compressor assembly

Installation Notes and Tips

Before installation, verify the vehicle uses R134A refrigerant and PAG 46 oil. This compressor is oil filled, but the fitment notes state it is filled with shipping oil only and must be drained and refilled before service. Replace the included O-rings during installation, confirm the 2-pin connector matches the vehicle harness, and inspect the serpentine belt drive and related A/C components before charging the system.

Quality Assurance

Nissens manufactures this compressor to OE standards and tests it for performance under high-stress operating conditions. The design emphasis on the pulley, clutch, hub, bearing, and wobble plate supports consistent operation in BMW 318i, 318is, 318ti, and Z3 A/C systems.
