The Chevrolet and Oldsmobile 1994-1996 internally equalized expansion valve rear, part number 38891, is an essential component of the automotive air conditioning system. This valve plays a crucial role in maintaining the optimal temperature and pressure within the system, ensuring the efficient operation of the air conditioner.

The internally equalized expansion valve is designed to regulate the amount of refrigerant that flows into the evaporator core. Its internal equalization feature allows the valve to maintain a consistent pressure difference between the high-pressure and low-pressure sides of the system, regardless of operating conditions. This ensures that the refrigerant flow rate remains constant, providing consistent and reliable cooling performance.

The valve body is constructed from durable materials, including brass and zinc alloys, to provide superior corrosion resistance and longevity. The valve features a metering orifice that controls the flow rate of refrigerant into the evaporator core, allowing for precise temperature control. The valve also includes a diaphragm that separates the high-pressure and low-pressure sides of the system, providing an effective barrier against leakage and contamination.

The 38891 expansion valve is designed to fit specifically in Chevrolet and Oldsmobile models from 1994 to 1996. Installation is a relatively straightforward process, and the valve comes with all necessary hardware for a hassle-free installation. The valve is compatible with R134a refrigerant, which was the standard refrigerant used during this time period.

In summary, the Chevrolet and Oldsmobile 1994-1996 internally equalized expansion valve rear, part number 38891, is a high-quality and essential component of the air conditioning system. Its internal equalization feature allows for consistent temperature and pressure control, while its durable construction ensures long-lasting performance. The valve is specifically designed to fit in Chevrolet and Oldsmobile models from 1994 to 1996 and is compatible with R134a refrigerant.
