🔧 A/C Compressor - Replacement

On your Equinox, the A/C compressor sits low on the engine and the refrigerant system must be properly recovered before any lines are opened. This job also requires belt removal, compressor oil handling, and a careful vacuum and recharge after installation.

Difficulty Level: Advanced | Estimated Time: 4-6 hours

---

⚠️ Safety & Precautions

• Have the refrigerant professionally recovered before starting. Never vent refrigerant.
• Wear safety glasses and gloves. Refrigerant can freeze skin and eyes instantly.
• Disconnect the negative battery cable before working near the belt drive and starter feed area.
• Keep dirt out of the open A/C lines. Cap every line immediately after disconnecting.
• Use only the correct A/C oil type and the correct amount for your system.
• If the old compressor failed internally, replace the receiver/drier or condenser as required by contamination level.

🔨 Step-by-Step Instructions

Follow these steps in order:

Step 1: Recover refrigerant and disconnect battery

• Use A/C recovery equipment to evacuate the refrigerant from the system.
• Use a wrench to disconnect the negative battery cable.

Step 2: Remove the engine air intake parts for access

• Use a socket set and trim clip removal tool to remove the intake ducting and any access covers blocking the front of the engine.
• Set all clips aside in order.

Step 3: Remove the serpentine belt

• Use a serpentine belt tool to rotate the tensioner and slip the belt off the compressor pulley.
• Inspect the belt for cracks or glazing. Replace it if worn.

Step 4: Disconnect the compressor electrical connector and A/C lines

• Use a metric socket or wrench to remove the compressor line bracket bolts, if equipped.
• Unplug the electrical connector from the compressor.
• Use the correct line wrench or socket to remove the A/C line fasteners.
• Cap the open lines immediately to keep out moisture and dirt.

Step 5: Remove the compressor

• Use a metric socket and ratchet to remove the compressor mounting bolts.
• Lower the compressor out of the vehicle.

Step 6: Prepare the new compressor

• Drain and measure the oil from the old compressor if possible.
• Use compressor oil to prefill the new compressor with the same amount removed, minus any oil added elsewhere in the system.
• Install new O-rings on the A/C line connections and lightly lubricate them with clean compressor oil.

Step 7: Install the new compressor

• Position the compressor and install the mounting bolts by hand first.
• Use a torque wrench to tighten the compressor mounting bolts to factory specification.
• Reconnect the A/C lines and tighten the fittings to factory specification.
• Reconnect the electrical connector.

Step 8: Reinstall the belt and intake parts

• Use the serpentine belt tool to route the belt back onto the pulleys.
• Reinstall the intake ducting and covers with the socket set and trim clip tool.

Step 9: Evacuate and recharge the system

• Use a vacuum pump and manifold gauge set to evacuate the system for at least 30 minutes.
• Verify the system holds vacuum.
• Recharge the system with the exact refrigerant amount specified on the underhood label using a refrigerant scale.

Step 10: Verify operation

• Reconnect the battery.
• Start the engine and turn the A/C on max.
• Check for abnormal noise, leaks, and proper cold air output.

✅ After Repair

• Check all A/C fittings for leaks with an electronic leak detector or UV dye if used.
• Confirm the compressor cycles normally and the air gets cold.
• Recheck belt tracking after a short road test.
• If the old compressor failed badly, replace any contaminated A/C components as needed.
