Key Features

• Aluminum core construction for efficient heat transfer.
• Designed for R134A refrigerant systems.
• O-rings included for a more complete service replacement.
• OE-standard manufacturing and testing.
• Core dimensions: 9.5669 in. length, 11.811 in. width, 1.9685 in. thickness.

Detailed Description

The Nissens 92858 evaporator core sits inside the HVAC module behind the dashboard, where it allows refrigerant to change from liquid to gas and absorb heat from the air stream. That process helps deliver cold cabin air and removes moisture from incoming air, which supports windshield and window defogging. For BMW owners servicing the HVAC system, this evaporator core provides the correct refrigerant-side dimensions and OE-level construction expected for the listed applications.

This part cross-references BMW 64119496922 for the same application.

What It Helps Address

• Weak or inconsistent cabin cooling.
• Moisture buildup that slows defogging.
• Leaks or corrosion in the evaporator core.
• HVAC performance loss from a worn internal heat exchanger.

Installation Notes and Tips

Verify refrigerant type, inlet and outlet sizing, and HVAC configuration before installation. This evaporator core is listed for BMW applications with N/A position data in most rows, with one front application noted for the Alpina XB7. Confirm the vehicles climate-control setup, including the X7 note for models without Five Zone Climate Control.

Quality Assurance

Nissens manufactures and tests evaporators to OE standards for fit and performance consistency.
