🔧 A/C Compressor - Replacement

Your CR-V’s A/C compressor pumps refrigerant through the system. On this model, the job requires refrigerant recovery before removal and a vacuum/charge after installation, so this is not a simple bolt-on swap.

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

⚠️ Safety & Precautions

• Do not vent refrigerant. The system must be recovered with A/C service equipment first.
• The refrigerant circuit may be under pressure and can cause frostbite or eye injury.
• Disconnect the negative battery cable before unplugging compressor wiring.
• Use jack stands on level ground if you need under-vehicle access.
• Keep dirt out of all open A/C lines and ports.
• Use the correct oil type and amount for the replacement compressor.

📋 Before You Begin

• Park on level ground and set the parking brake.
• Let the engine cool fully.
• Recover the refrigerant with proper A/C equipment before opening the system.
• Disconnect the negative battery cable.
• If the belt looks worn or glazed, replace it now.
• Label and keep track of the A/C lines so they go back in the same place.

🔨 Step-by-Step Instructions

Follow these steps in order:

Step 1: Recover the refrigerant

• Use a refrigerant recovery machine to remove all refrigerant from the system.
• Do not disconnect any A/C lines until the system is empty.
• Never vent refrigerant.

Step 2: Disconnect the battery

• Use a 10mm socket to disconnect the negative battery cable.
• This prevents accidental short circuits while working on the compressor wiring.

Step 3: Remove the engine cover and access parts

• Remove the engine cover if equipped.
• Use a trim clip removal tool and 10mm socket to remove any splash shields or intake duct parts blocking access.
• If needed, raise the front of the vehicle and support it with jack stands.

Step 4: Remove the drive belt

• Use a serpentine belt tool to release belt tension.
• Slip the belt off the A/C compressor pulley and remove it from the engine.
• Take a photo of the belt path first.

Step 5: Unplug the compressor

• Use your hand to disconnect the electrical connector from the compressor.
• Check the connector for corrosion or broken tabs.

Step 6: Disconnect the A/C lines

• Use a line wrench set to loosen the refrigerant line bolts at the compressor.
• Remove the lines carefully and catch any oil with a drain pan.
• Cap the open lines right away so dirt does not enter.

Step 7: Remove the compressor

• Use a 12mm socket and 14mm socket to remove the compressor mounting bolts.
• Support the compressor with one hand while removing the last bolt.
• Lift the compressor out from the engine bay.

Step 8: Prepare the replacement compressor

• Compare the new compressor to the old one before installing.
• Drain and measure any oil from the old unit if required by the replacement procedure.
• Add the correct amount of A/C compressor oil to the new compressor.
• Install new A/C compressor O-rings and lightly coat them with clean refrigerant oil.

Step 9: Install the compressor

• Set the compressor in place by hand.
• Install the mounting bolts with a 12mm socket and 14mm socket.
• Torque to 24 Nm (18 ft-lbs) unless your service data for the exact fastener location specifies otherwise.
• Reconnect the refrigerant lines and tighten them evenly.
• Torque to 16 Nm (12 ft-lbs) on the line bolts unless service data specifies otherwise.

Step 10: Reinstall the belt and covers

• Route the accessory drive belt back over the pulleys.
• Use the serpentine belt tool to release the tensioner and slip the belt into place.
• Reinstall any splash shields, ducts, and covers with a 10mm socket and trim clip removal tool.

Step 11: Evacuate and recharge the system

• Use a vacuum pump and manifold gauge set to pull a deep vacuum on the A/C system.
• Hold vacuum and check for leaks before charging.
• Recharge the system with the correct refrigerant amount for your CR-V and verify proper oil balance.
• Charge by weight, not by pressure alone.

✅ After Repair

• Reconnect the battery with a 10mm socket.
• Start the engine and turn the A/C to MAX cold.
• Check that the compressor engages smoothly and that both lines begin to change temperature.
• Inspect for refrigerant leaks at the compressor fittings.
• Verify vent temperature after several minutes of idle and light engine speed.
