🔧 Charger - A/C Compressor Replacement

Replacing the A/C compressor on your Charger involves safely recovering refrigerant, removing the drive belt, disconnecting the A/C lines, swapping the compressor, then vacuuming and recharging the system. The exact parts list and torque specs depend on whether the old compressor failed internally and contaminated the system.

Difficulty Level: Advanced | Estimated Time: 3-6 hours

⚠️ Safety & Precautions

• ⚠️ Refrigerant is under high pressure—do not loosen A/C lines unless the system is fully recovered with proper equipment.
• ⚠️ Wear eye protection and gloves; refrigerant/oil can cause frostbite and eye injury.
• ⚠️ Keep hands clear of the belt path; the tensioner is spring-loaded.
• ⚠️ If you’ll unplug the compressor clutch/pressure sensor connectors, disconnect the battery negative cable first.

📋 Before You Begin

• Park on level ground, set the parking brake, and chock the rear wheels.
• Have the refrigerant professionally recovered if you don’t have a recovery machine.
• If you’ll be unplugging electrical connectors near the compressor, disconnect the battery negative cable using a 10mm socket.
• Take a photo of the belt routing.

🔨 Step-by-Step Instructions

Follow these steps in order:

Before I give you the exact step-by-step with correct torque specs and the right “replace these parts too” guidance, answer these 2 quick questions:

• Did the old compressor fail loudly/lock up or did it just stop cooling (no noise)? This determines whether you must replace the condenser/receiver-drier and flush lines due to metal contamination.
• Will you be using a recovery machine + vacuum pump + manifold gauges yourself, or will a shop handle the recover/evac/recharge portion?

Once you reply, I’ll give you the exact procedure path for your Charger (including what to replace, what to flush, and the torque specs at each fastener/line connection).

✅ After Repair

• Verify the system holds vacuum, then recharge by weight (not by pressure alone).
• Confirm vent temperature drop and stable low/high side pressures.
• Check for leaks at every opened connection.
