Bosch 1986AD1002 A/C Compressor

Bosch A/C Compressor for Mercedes-Benz

The Bosch 1986AD1002 A/C compressor is built for Mercedes-Benz HVAC systems that need OE-style fitment and dependable refrigerant control. It is engineered for R134A and R1234YF applications and uses PAG YF 46 oil, making it a direct replacement choice for a wide range of Mercedes-Benz ML350, C350, E350, and G550 models.

Bosch’s A/C compressor line draws on OE manufacturing experience and a controlled release process with testing for endurance, performance, vibration, leaks, salt spray, and noise. The result is a compressor built to match OE casting, pulley, and connector specifications for cleaner installation and proper system alignment.

Detailed Description

This Bosch A/C compressor is a fitment-based replacement for Mercedes-Benz HVAC systems across model years from 2000 through 2013. It is listed for applications including 2012-2013 Mercedes-Benz ML350, 2006-2009 Mercedes-Benz C350, 2009-2012 Mercedes-Benz G550, 2007-2011 Mercedes-Benz CLS550, and 2003-2011 Mercedes-Benz G55 AMG.

This part cross-references OE-style numbers such as 0012301911 and 0032308011 for the same application. It is a practical replacement for Mercedes-Benz A/C compressor service when the original unit has lost cooling output, developed noise, or no longer maintains proper system pressure.

What It Helps Solve

• Weak or inconsistent cabin cooling
• Compressor noise, vibration, or rough operation
• Refrigerant leaks at the compressor assembly
• Loss of system pressure or poor A/C cycling
• Fitment issues when replacing an OE Mercedes-Benz compressor

Installation Notes and Tips

Verify refrigerant type, pulley configuration, connector style, and OE part number before installation. This compressor is oil filled and uses PAG YF 46, so the system should be serviced with the correct refrigerant oil specification. Confirm the seal ring condition during replacement and inspect the belt drive, condenser, and expansion components before recharging the system.
