NISSAN 92131-VC71C A/C Receiver Drier

Genuine Nissan (OEM) A/C receiver drier (OEM part number: 92131-VC71C), a critical protective and functional component of the vehicle's air conditioning system. Known in OEM technical documentation as "TANK ASSY-LIQUID", this part plays a key role in maintaining the purity and operational efficiency of the refrigeration cycle.

Operating Principle and Function:
The receiver drier is positioned on the high-pressure side of the A/C system, between the condenser and the expansion valve. Its primary role is the temporary storage of liquid refrigerant, along with filtering out circulating debris and moisture from the system. A specialized desiccant (silica gel or molecular sieve) inside the unit absorbs microscopic moisture present in the refrigerant. This is vital, as moisture can react with refrigerant and oil to form acids causing internal corrosion, or freeze at the expansion valve to block refrigerant flow, resulting in catastrophic A/C compressor failure.

Key Technical Specifications:

• Manufacturer: Nissan (Genuine OEM)
• Part Number: 92131-VC71C
• Product Type: A/C Receiver Drier (Tank Assy-Liquid)
• Housing Material: High-strength, corrosion-resistant aluminum alloy designed to withstand high operating pressures
• Filter Media: Integrated high-capacity desiccant and fine particulate filter layer
• Applicable Refrigerants: R134a and modern environmentally friendly refrigerants (according to system specifications)

Signs of Failure or Wear:

• Diminished or completely absent cooling performance in the cabin.
• Pressure fluctuations or abnormal pressure spikes within the A/C system.
• Noisy compressor operation or frequent clutch cycling.
• Frost formation or excessive condensation on the surface of the receiver drier body (indicating an internal restriction or blockage).

Installation Recommendation: Whenever the refrigerant circuit is opened or any major A/C component (compressor, condenser, lines) is replaced, replacing the receiver drier is technically mandatory, as exposure to ambient air rapidly saturates the desiccant material and degrades its moisture-absorbing capability.
