Four Seasons 38886 A/C Expansion Valve

Four Seasons 38886 Expansion Valve Overview

Four Seasons 38886 is a block-type A/C expansion valve for R134A systems. Built from aluminum and configured as a w/o solenoid valve, it meters refrigerant flow to help maintain proper evaporator performance in service applications that call for an OE-style replacement.

For technicians servicing HVAC systems on vehicles such as Honda Civic and Toyota Corolla applications, this expansion valve supports accurate refrigerant control at the evaporator inlet. The Four Seasons Expansion Valve line focuses on direct-fit replacement parts for automotive air conditioning repairs.

Detailed Description

Four Seasons 38886 is an A/C expansion valve used to regulate refrigerant entering the evaporator, helping the HVAC system maintain the correct pressure drop and refrigerant metering. It features female suction and liquid connections with insert O-ring styles, including No. 8 and No. 10 suction fittings and No. 6 and No. 8 liquid fittings. The valve is specified for R134A systems and uses an 8.000 super heat setting for controlled refrigerant flow. If you are replacing a worn HVAC metering component on a Honda Civic or Toyota Corolla, this OE-style valve provides the fitment and connection style commonly required in automotive A/C service.

This part cross-references Gates 19837 and UAC EX9461C for the same application.

What It Helps Fix

• Weak or inconsistent cabin cooling
• Incorrect refrigerant metering at the evaporator
• Frosting or poor evaporator performance caused by flow control issues
• A/C pressure irregularities tied to a failing expansion valve
• HVAC service repairs requiring a block-type R134A expansion valve

Installation Notes and Tips

Verify the system uses R134A refrigerant and confirm the block-type valve layout before installation. Match the suction and liquid fitting sizes, O-ring style, and mounting hole layout to the original component. Replace seals as needed during A/C service, evacuate the system properly, and recharge to the vehicle manufacturer’s specification after repair. Confirm the application details for the specific Honda Civic or Toyota Corolla model year before ordering.

Quality Assurance

Four Seasons lists this expansion valve as meeting or exceeding OEM requirements, making it a direct replacement option for professional HVAC repair work.
