A-Premium A/C Discharge Line Hose Assembly for 3.6L GM V6 — 2nd-Design Routing, OE-Style Connectors

This A-Premium A/C discharge line hose assembly replaces the high-pressure line from compressor to condenser for select 3.6L Chevrolet, GMC, Buick and Saturn models.

If your vehicle’s air conditioning has reduced cooling or you see refrigerant oil at the hose connections, the discharge line is a common high-pressure wear point. This replacement hose is designed to match the 2nd-design routing and fittings used on specific 2010–2015 GM vehicles with the 3.6L V6. It arrives preassembled with OE-style connectors and is offered with a one-year unlimited-mileage warranty for added confidence.

How do I know this hose fits my vehicle?

Fitment is limited to second-design A/C discharge hose configurations. Check your vehicle’s existing hose shape and connector orientation against photos or your dealership parts reference to confirm compatibility. The assembly fits Chevrolet Traverse (2010–2013), GMC Acadia (2010–2015), Buick Enclave (2010–2012) and Saturn Outlook (2010) all with the 3.6L V6 where the second-design hose was used.

• Fits 3.6L V6 GM vehicles as listed: Traverse, Acadia, Enclave, Outlook
• Only compatible with second-design discharge lines — not first-design
• Reference numbers: HA111990C, 19356341, 22757062, T56450

What does this hose replace and what are the benefits?

This part replaces the high-pressure discharge line that carries refrigerant from the compressor to the condenser. Replacing a cracked or leaking line restores proper system pressure, prevents refrigerant loss and helps the climate system produce cooler air. The assembly uses OE-style fittings to simplify installation and restore factory routing.

• Direct replacement for the compressor-to-condenser discharge line
• OE-style connectors for improved seal and easier installation
• Helps eliminate refrigerant leaks and pressure loss in the system

What should I check before purchasing or installing?

Confirm your vehicle year, engine size (3.6L V6) and that the original discharge hose matches the second-design shape and fittings. If unsure, compare part reference numbers or capture photos of the existing hose ends for verification. Also note that A/C service requires proper refrigerant handling — installation by a qualified technician is recommended if you’re not experienced.

• Verify 3.6L V6 engine and listed model years/submodels
• Confirm second-design hose configuration before ordering
• Plan A/C system evacuation and recharge by certified technician
