Four Seasons 39616 Expansion Valve Overview

Four Seasons 39616 is a block-type A/C expansion valve built from aluminum for R134A systems. It meters refrigerant flow through the HVAC circuit to help maintain proper evaporator performance in Audi applications that use an expansion valve with R1234yf service notes in the fitment data.

This Four Seasons Expansion Valve line is focused on OE-style replacement coverage and direct-fit service parts for late-model Audi HVAC repairs. Part number 39616 is listed as a no-solenoid design with sealing-washer connections and a 1.000 tonnage rating.

Detailed Description

Four Seasons 39616 is an A/C expansion valve for HVAC systems that require precise refrigerant control at the evaporator. By regulating liquid refrigerant flow, it supports stable cabin cooling performance and proper system balance in Audi A4, A5, A6, Q5, RS5, RS6, RS7, S4, S5, S6, S7, SQ5, SQ8, and e-tron applications listed in the fitment data. This part number 39616 is a direct replacement option for service work where the original valve uses a block-style layout and sealing-washer connections.

This part cross-references UAC EX10658C for the same application.

What It Helps Address

  • Weak or inconsistent A/C cooling
  • Improper refrigerant metering at the evaporator
  • HVAC performance loss from a worn expansion valve
  • Temperature fluctuation inside the cabin
  • Service replacement for leaking or restricted valve assemblies

Installation Notes and Tips

Verify refrigerant type, fitting style, and thread dimensions before installation. Confirm the vehicle uses the listed expansion valve configuration and match the sealing-washer connections to the original HVAC layout. For Audi A4, A5, A6, Q5, and related models, compare the original valve body, mounting-hole pattern, and line connections to Four Seasons 39616 before reassembly. Always evacuate and recharge the system according to factory service procedures after HVAC component replacement.

Quality Assurance

Four Seasons lists this expansion valve as meeting or exceeding OEM requirements. The aluminum construction and OE-style block design support consistent service replacement for late-model Audi HVAC systems.
