Four Seasons 39077 A/C Expansion Valve

Four Seasons 39077 Expansion Valve Overview

Four Seasons 39077 is a block-type A/C expansion valve for R134A systems. Built from aluminum and engineered to meet or exceed OEM requirements, it is specified for 1.0 ton applications with an 8.0 superheat setting.

This Four Seasons Expansion Valve line focuses on accurate refrigerant control and OE-style fitment for service work on Chrysler Sebring, Dodge Stratus, and Mitsubishi Eclipse HVAC systems. Part number 39077 is a direct replacement style component for vehicles using captured O-ring connections and a w/o solenoid design.

Key Features

• Block-type A/C expansion valve for R134A refrigerant systems
• Aluminum construction with aluminum finish
• Meets or exceeds OEM specifications
• Captured O-ring liquid and suction connections
• Female inlet and outlet fittings
• Designed for 1.0 ton HVAC applications
• Superheat setting: 8.0
• Style: w/o solenoid

Detailed Product Description

Four Seasons 39077 regulates refrigerant flow into the evaporator to help maintain proper A/C system performance. The block-type design uses female suction and liquid fittings with captured O-ring sealing surfaces, including No. 12 suction inlet and outlet thread diameters and No. 6 liquid inlet with No. 10 liquid outlet thread diameters. This configuration supports service replacement on 2000-2005 Mitsubishi Eclipse, 2001-2005 Chrysler Sebring, and 2001-2005 Dodge Stratus applications that use the same expansion valve layout.

This part cross-references UAC EX10073C for the same application. If you are replacing a worn or restricted valve on a Chrysler Sebring, Dodge Stratus, or Mitsubishi Eclipse, Four Seasons 39077 provides the correct OE-style form and refrigerant control characteristics for the listed fitments.

Common Problems This Part Can Address

• Weak or inconsistent cabin cooling
• Improper refrigerant metering at the evaporator
• A/C performance loss caused by a restricted expansion valve
• System service needs on R134A-equipped HVAC systems
• Fitment replacement for vehicles with captured O-ring block-style valves

Installation Notes and Tips

Verify the vehicle’s A/C system uses the same block-type valve layout, captured O-ring connections, and R134A refrigerant specification before installation. Inspect mating surfaces and replace damaged seals during service. Confirm the suction and liquid port sizes match the original component on the vehicle.

Compatible With 2000-2005 Mitsubishi Eclipse, 2001-2005 Chrysler Sebring, and 2001-2005 Dodge Stratus. Part number 39077 should be matched to the original valve style and connection layout for proper fitment.

Quality Assurance

Four Seasons 39077 is built to meet or exceed OEM requirements for the listed applications, supporting consistent replacement quality for HVAC service work.
