jasperautopart Rear A/C Block Off Kit for 2007–2015 Chevy Traverse & GMC Acadia — 6061 Aluminum Cap, Seal Tape

This rear A/C block off kit seals and disables the rear air-conditioning circuit so you can remove a leaking or failed rear evaporator without replacing the entire rear A/C system.

If the rear air conditioner in your 2007–2015 Chevy Traverse, TrailBlazer, GMC Acadia, Buick Enclave or Chrysler Town & Country has failed, replacing the full rear evaporator and lines can be expensive and time-consuming. The jasperautopart Rear A/C Block Off Kit provides a practical, durable alternative: it isolates and seals the rear A/C lines inside the engine compartment so the front A/C remains fully operational while the rear circuit is safely decommissioned.

How does this kit stop a leaking rear A/C without major repairs?

The kit replaces the rear refrigerant line connection with a machined aluminum cap and includes sealing tape so the open circuit is fully closed off. By blocking the rear line where it joins the main harness, refrigerant and oil are retained in the front system and the damaged rear components can be removed or ignored.

• Precision CNC-machined 6061 billet aluminum cap for a tight fit
• High-temperature corrosion-resistant construction prevents future degradation
• Included sealing tape ensures 100% sealing at the connection point

Will installing the jasperautopart kit affect front A/C performance?

No — installing the block off kit isolates only the rear loop while leaving the vehicle’s front A/C circuit intact and functional. The design maintains proper front-system pressure and eliminates cross-contamination from a compromised rear evaporator or lines.

• Seals the rear circuit to preserve refrigerant and oil for the front system
• Prevents refrigerant loss or contamination from a leaking rear evaporator
• Supports continued use of front vents and climate control

How difficult is installation for a home mechanic?

Installation is straightforward for anyone comfortable working in the engine bay and disconnecting A/C lines; no special tooling beyond common hand tools is usually required. The kit is designed to be installed where the rear lines enter the engine compartment: remove the failing rear line, fit the block-off cap, and wrap the connection with the supplied sealing tape.

• Simple disconnect of rear lines and fitting of the block-off cap
• Clear fitment for compatible 2007–2015 models reduces trial-and-error
• Comes with seal tape to finish the junction cleanly and securely

What materials and components are included, and how durable is it?

The jasperautopart kit is machined from 6061 billet aluminum for high heat tolerance and corrosion resistance, providing a strong long-term seal under engine-bay conditions. Components are minimal but purposeful: the block-off cap and a roll of sealing tape to ensure a leak-free closure.

• 6061 CNC-machined billet aluminum cap for strength and thermal resistance
• Anti-corrosion finish suited for engine compartment exposure
• One rear A/C block off cap plus seal/organize tape included in the package

Who this is for: This kit is ideal for owners of 2007–2015 Chevy Traverse, TrailBlazer, GMC Acadia, Buick Enclave or Chrysler Town & Country vehicles who want a cost-effective way to eliminate a failing rear A/C circuit without paying for expensive rear evaporator and line replacement. It's also a practical option for fleet vehicles, project cars, or anyone seeking a reliable, serviceable solution that preserves front A/C functionality while isolating a problematic rear system.
