A-Premium AC Expansion Valve for Chevrolet, Buick & Cadillac — Direct-Fit Aluminium Replacement for Stable Cooling

If your vehicle's air conditioning is inconsistent, blows warm at idle, or cycles irregularly, a failing expansion valve is often the cause. This A-Premium unit is designed to match factory dimensions and mounting points while providing precision internal components to regulate refrigerant metering for steady cabin comfort. Constructed from aluminum and finished to OEM standards, it aims to deliver long-lasting service and straightforward installation for compatible models.

Which vehicles will this expansion valve fit?

This valve is made to fit a wide range of General Motors platforms and certain Saab models from model years around 2010–2017. Compatibility covers multiple engine sizes and variations across Chevrolet Cruze and Malibu lines, Buick LaCrosse, Regal and Verano, Cadillac SRX trims, and the Saab 9-4X.

• Chevrolet: Cruze (2011–2016) and Malibu (2013–2016) engine variants listed in product notes.
• Buick: LaCrosse, Regal and Verano models spanning listed years and engine types.
• Cadillac & Saab: SRX (2010–2016) and Saab 9-4X (2011) with compatible V6 engines.

How does this A-Premium valve affect AC performance?

The expansion valve controls refrigerant flow into the evaporator; a correctly functioning valve helps the AC reach target temperatures faster and keeps cooling stable under different loads. Replacing a worn valve can reduce temperature swings and improve system efficiency without replacing the entire HVAC system.

• Precision internals meter refrigerant for consistent evaporator pressure and temperature.
• Aluminum construction resists corrosion and helps maintain tight tolerances.
• OEM-style fit reduces leak points and simplifies installation compared to custom adapters.

What are the build and quality specifics of this replacement part?

Manufactured from aluminum to meet or exceed OEM quality, this A-Premium expansion valve is delivered brand-new and inspected for dimensional accuracy. It carries multiple reference numbers to match factory parts and is backed by a limited guarantee for added buyer confidence.

• Material: durable aluminum alloy for strength and corrosion resistance.
• Reference numbers: 13313727, 20782085, 3411488, 52427385, 52441222 for cross-referencing.

How do I install or verify fitment before buying?

Check your vehicle’s parts manual or existing expansion valve reference number against the listed references. Installation typically requires evacuation of refrigerant and basic HVAC tools; professional installation is recommended if you lack AC system experience.

• Compare the OEM reference number on your current valve with the product references above.
• Ensure the valve’s mounting holes and line fittings match your evaporator and refrigerant lines.
• Have the system vacuumed and recharged to manufacturer refrigerant specs after replacement.

Who is this for: This A-Premium AC Expansion Valve suits DIY mechanics and professional technicians working on compatible Chevrolet, Buick, Cadillac and Saab models who need an affordable, OEM-style replacement. It's ideal for vehicles experiencing inconsistent cooling, frequent compressor cycling, or when the original valve is leaking or damaged. If you want a direct-fit aluminum replacement with cross-reference numbers and a one-year guarantee, this part is built to meet those needs.
