Four Seasons 39073 Expansion Valve Overview

Four Seasons 39073 is a block-type A/C expansion valve for R134A systems. Built from aluminum and engineered to meet or exceed OEM specifications, it regulates refrigerant flow to help maintain stable evaporator performance in the HVAC system.

This Four Seasons Expansion Valve line is used in automotive air conditioning service where precise refrigerant metering matters. For technicians servicing Honda Civic, Toyota Corolla, and similar passenger vehicles, Four Seasons 39073 provides an OE-style replacement path for R134A applications.

Product Details

Four Seasons 39073 meters liquid refrigerant into the evaporator through a block-style design with female O-ring fittings. The valve uses No. 6 liquid inlet and No. 8 liquid outlet thread diameters, along with No. 10 suction inlet and outlet thread diameters, for service applications that require this connection layout. The aluminum body supports corrosion resistance in standard automotive HVAC environments, and the OE-level specification helps maintain proper refrigerant control in R134A systems.

This part cross-references FEL-PRO 1602 and 1603 for the same application. If you are replacing a worn A/C expansion valve on a Honda Civic, Toyota Corolla, or another vehicle using this configuration, Four Seasons 39073 is a direct service part to verify against the original component.

What It Helps Fix

  • Inconsistent cabin cooling caused by poor refrigerant metering
  • Evaporator performance issues from a sticking or restricted valve
  • A/C pressure imbalance in R134A systems
  • Temperature swings at the vents during compressor cycling
  • Loss of cooling efficiency from a failing expansion valve

Installation Notes and Tips

Confirm the original valve style, refrigerant type, and fitting dimensions before installation. Replace damaged O-rings and inspect the mating surfaces for wear or contamination. Evacuate and recharge the system according to the vehicle service procedure after the valve is installed. Verify system pressures and vent temperature once the repair is complete.

Quality Assurance

Four Seasons 39073 is built to meet or exceed OEM specifications for the listed application type. The Four Seasons Expansion Valve line is used in automotive HVAC service where accurate refrigerant control and fitment consistency are required.
