Description

Product Overview

The Rear AC Block Off Kit from Auto Cooling Solutions is engineered to permanently disable the rear air‑conditioning circuit in 1999‑2003 Toyota Sienna vans. Each fitting is CNC machined from high‑grade aluminum, ensuring precise tolerances and a leak‑free seal. Weighing only 8 ounces and measuring 5 x 3 x 3 inches, the kit includes all necessary components—block off fittings, O‑rings, and a step‑by‑step installation guide—so you can complete the conversion without professional tools.

FAQ

Do I need special tools to install the kit?

No special tools are required. A basic set of hand tools—such as a wrench and screwdriver—along with the supplied clamps and O‑rings are sufficient for a complete installation.

Will this kit affect the front A/C performance?

Installing the block off kit isolates the rear circuit, allowing the front system to operate without the additional load of the rear evaporator. This often results in slightly improved front cooling efficiency.

Can the kit be removed if I decide to reinstall the rear A/C?

Yes. The fittings are designed for reversible installation. By removing the block off components and reinstalling the original rear lines, you can restore the rear A/C functionality.

Is this kit compatible with other Toyota models?

The kit is specifically engineered for the 1999‑2003 Toyota Sienna. While it may physically fit similar models, we recommend using the exact matching kit for optimal performance and warranty compliance.
