• Part number 9991065 for catalog and service lookup

Detailed Description

Nissens 9991065 regulates refrigerant flow into the evaporator on compatible Honda Accord A/C systems, helping maintain proper system balance between pressure, temperature, and cooling output. This block-type expansion valve is specified for 2003-2007 Honda Accord models and uses aluminum construction with R134 refrigerant compatibility. Nissens also validates each valve for opening characteristics, sealing, pressure control, and internal surface finish to support consistent OE-style operation. This part cross-references Four Seasons 39021 for the same application.

For Honda Accord A/C repair work, the Nissens 9991065 is a direct-fit service part for restoring refrigerant metering performance in the HVAC circuit.

What It Helps Fix

• Weak or inconsistent cabin cooling
• Incorrect refrigerant metering at the evaporator
• A/C pressure imbalance caused by a worn valve
• Temperature fluctuations during compressor cycling
• System performance issues after A/C service or component replacement

Installation Notes and Tips

Replace the expansion valve during A/C service when the system has been opened, contaminated, or shows signs of restricted refrigerant flow. Inspect mating surfaces, replace the included O-rings with clean refrigerant oil, and verify correct torque on the mounting hardware. Evacuate and recharge the system to the vehicle specification after installation. Confirm the vehicle is a 2003-2007 Honda Accord before ordering.

Quality Assurance

Nissens manufactures this expansion valve to precise OE-matching standards and tests pressure performance, tightness, opening behavior, set-point setting, and internal finish before release. Part number 9991065 is built for consistent service replacement on the listed Honda Accord applications.
