A-Premium A/C Suction Hose Assembly for GM 3.6L V6 (2009–2012) — Direct Replacement, 4-Layer Durability

This suction hose connects the compressor to the evaporator and is built to meet the demands of Chevrolet Traverse, GMC Acadia, Buick Enclave, and Saturn Outlook models with the 3.6L V6 gasoline engines from the 2009–2012 model years. The assembly offers a robust multilayer construction designed to resist abrasion, collapse, and wide temperature swings so your vehicle’s HVAC system can maintain efficient cooling performance.

How will this hose improve my vehicle’s A/C performance?

Replacing a worn or leaking suction hose eliminates loss of refrigerant and helps the system maintain correct pressure. That means faster cooling, reduced compressor strain, and fewer A/C cycling issues during hot weather.

• Stops refrigerant leaks that lower cooling output
• Maintains manufacturer-like low-side pressure for efficient operation
• Reduces stress on the compressor and related components
