Introduction

This tutorial provides a step-by-step guide for replacing the AC compressor in a 2017 Ford Explorer with a 3.5-liter AWD engine. If your AC system is not functioning properly and you suspect a compressor issue, this guide will help you perform the replacement yourself, saving time and money.

Step 1: Gather Required Tools and Parts

Before starting the replacement, ensure you have all necessary tools and parts ready.

Tools Needed

• Socket set
• Wrench set
• Screwdrivers
• AC compressor installation tool (optional)
• Torque wrench

Parts Required

• New AC Compressor (available here)
• R-134a Freon (available here)
• PAG 46 Oil (available here)

Step 2: Prepare the Vehicle

Ensure the vehicle is parked on a level surface, and the engine is turned off.

• Disconnect the negative battery cable to prevent any electrical shorts.
• If applicable, remove any necessary covers to access the engine compartment.

Step 3: Remove the Old AC Compressor

Follow these sub-steps to safely remove the old compressor:

1. Locate the AC Compressor: Identify the compressor unit, which is typically found mounted on the front of the engine.
2. Disconnect Electrical Connectors: Carefully unplug any electrical connectors attached to the compressor.
3. Remove Refrigerant Lines: Use a wrench to disconnect the refrigerant lines from the compressor. Be cautious, as some residual refrigerant may still be present.
4. Unbolt the Compressor: Remove the mounting bolts securing the compressor to the engine. Keep these bolts as you will need them for installation.
5. Lift Out the Compressor: Gently lift the old compressor out of the engine bay.

Step 4: Install the New AC Compressor

Now install the new compressor following these steps:

1. Add PAG Oil: Before installation, add the appropriate amount of PAG 46 oil into the new compressor to ensure proper lubrication.
2. Position the New Compressor: Place the new compressor in the same location as the old one.
3. Secure with Bolts: Reinstall the mounting bolts and tighten them to the manufacturer’s specifications using a torque wrench.
4. Reconnect Refrigerant Lines: Attach the refrigerant lines to the new compressor, ensuring they are sealed properly.
5. Reconnect Electrical Connectors: Plug in the electrical connectors to the new compressor.

Step 5: Recharge the AC System

After installing the new compressor, you will need to recharge the AC system with R-134a Freon.

1. Connect the Refrigerant Can: Attach the refrigerant can to the low-pressure service port.
2. Check for Leaks: Before adding Freon, check all connections for leaks. Use a leak detection kit if necessary.
3. Add Freon: Following the manufacturer’s guidelines, slowly add R-134a Freon to the system.
4. Test the AC System: Start the engine and turn on the AC to test if the system is working properly. Monitor the pressure gauges during this process.

Conclusion

Replacing the AC compressor in a 2017 Ford Explorer can be accomplished with the right tools and careful attention to detail. Remember to follow safety protocols, and always check for leaks after recharging the system. If you encounter any issues, consulting a professional mechanic is recommended. Enjoy a cool ride with your newly installed AC system!
