Detailed Description

This Bosch A/C compressor, part number 1986AC1049, is engineered to match OE casting, pulley, and connector specifications for straightforward replacement service. Bosch subjects the compressor to endurance, performance, vibration, leak, salt spray, and noise testing to verify durability and operating consistency under demanding conditions. For Dodge Ram 1500, Ram 2500, and Ram 3500 applications, the compressor is built to support proper refrigerant circulation and stable HVAC operation.

The Bosch A/C Compressor product line focuses on replacement components that align with original equipment specifications. That means the compressor is built around the dimensions and connection points needed for a direct service replacement, while maintaining the refrigerant and oil requirements expected in the system. Part number 1986AC1049 is a practical choice when replacing a worn or noisy compressor on compatible Dodge Ram trucks.

This part cross-references Mopar 55056336AA and 55056336AB for the same application.

What It Is Used For

• Restoring cooling performance when the compressor is no longer building pressure correctly.
• Addressing unusual compressor noise, vibration, or rough operation.
• Replacing a unit with refrigerant leakage or seal wear.
• Supporting proper A/C system function after compressor failure.

Installation Notes and Tips

Verify refrigerant type, oil specification, pulley groove count, and connector match before installation. Confirm the system is clean and properly evacuated, and inspect related A/C components for contamination or wear before installing the new compressor. Use the OE-matched specifications to compare the replacement unit against the original part number 1986AC1049.
