2002-2019 Ford Explorer Rear AC Line Repair Options

If your Ford Explorer's rear A/C has stopped working, you have two paths forward: replace the lines with a direct-fit A/C line set, or permanently eliminate the rear system with a block off kit. Auto Cooling Solutions manufactures both options right here in the USA — no cutting, splicing, or modification required.

This guide covers which option is right for your situation and lists the exact parts that fit your Explorer by year and engine.

Which Option Is Right for You?

Option 1 — A/C Line Set (Restore Rear A/C Function)

Auto Cooling Solutions offers a direct-fit rear A/C line set for the 2011–2016 Ford Explorer. These are full-length replacement lines built from high-pressure barrier hose with machined aluminum bolt-up ends — no modifications, no adapters.

Option 2 — A/C Block Off Kit (Permanently Cap the Rear System)

If the rear A/C on your Ford Explorer is leaking, damaged, or simply no longer needed, a block off kit is the cleanest solution. Our machined aluminum fittings bolt directly onto the existing Ford Explorer rear A/C ports — sealing the system permanently so your front A/C continues to operate normally.

We offer two block off kit options for the Ford Explorer depending on your year and port configuration:
