What this product does:
• Regulates refrigerant flow from high to low pressure
• Maintains optimal evaporator performance for steady cooling
• Protects the A/C compressor and system from pressure imbalance
Why replacement matters:
A faulty expansion valve can cause poor cooling, fluctuating cabin temperatures, evaporator freeze-up, or compressor strain. Replacing valve restores efficient air conditioning, ensures passenger comfort, and protects the A/C system from costly damage.
