Nissens 89090 A/C Compressor

Nissens 89090 A/C Compressor Overview

The Nissens 89090 A/C compressor is a direct-fit HVAC replacement for select Mercedes-Benz and Dodge Sprinter applications. Built around a 7SEU17C compressor design and pre-filled with PAG oil, it supports R134A systems and is specified for vehicles that require PAG 46 lubricant.

For Mercedes-Benz Sprinter 2500, Sprinter 3500, and Sprinter 3500XD service work, this compressor is a practical OE-style replacement for restoring cabin cooling performance. The Nissens 89090 also cross-references common aftermarket and OE numbers for the same application.

Detailed Description

Nissens develops thermal management components for aftermarket use with a focus on consistent manufacturing quality and application-specific fitment. The 89090 A/C compressor is built for vehicles using R134A refrigerant and a 7SEU17C compressor configuration, making it a direct replacement choice for many Mercedes-Benz Sprinter 2500 and Sprinter 3500 models, along with select Sprinter 3500XD applications. It also fits several Mercedes-Benz passenger and utility models, including CL600, CL65 AMG, S600, S65 AMG, GL350, R350, ML350, SL65 AMG, and others listed in the fitment data.

This part cross-references Delphi CS20094 and Valeo 813427 for the same application.

What It Helps Solve

• Weak or no cabin cooling from a worn compressor
• Noisy compressor operation caused by internal wear
• Loss of refrigerant circulation in an R134A system
• Air conditioning performance issues on Mercedes-Benz Sprinter 2500 and Sprinter 3500 models
• Replacement needs for select Mercedes-Benz CL600, S600, and GL350 applications

Installation Notes and Tips

Before installation, verify the vehicle uses R134A refrigerant and PAG 46 oil. The compressor is pre-filled with shipping oil only on certain Sprinter applications, so drain and refill as noted in the fitment data before commissioning the system. Always inspect the system for contamination, replace the receiver/drier or accumulator as required by service procedure, and evacuate the system before recharging.

Confirm the pulley groove count and compressor type match the original unit before installation. Use the vehicle-specific fitment notes for Mercedes-Benz and Dodge Sprinter applications, especially where auxiliary A/C or production-date notes are listed.

Quality Assurance

Nissens positions this compressor within its Genuine Nissens Quality standard, with products developed and manufactured to meet aftermarket thermal-management requirements. The 89090 is built as a FIRST FIT replacement to support efficient service on compatible Mercedes-Benz and Dodge Sprinter applications.
