Is the air conditioning in your Chevy Trax or Buick Encore not blowing cold? If you see oily residue or hear a hissing sound from under the hood, you might have a leak in one of the AC lines. This replacement air conditioning pipe is designed to fix that. It's a direct fit for the 2015-2017 Chevy Trax and the 2013-2015 Buick Encore, replacing OEM part numbers like 42588256, 95376436, and 42366105. It's made from high-quality, corrosion-resistant materials that can handle the pressure and temperature of the AC system. The connections are precision-machined with good seals to prevent new leaks after installation. Swapping it out is a job for someone with some mechanical skill (you'll need to evacuate and recharge the AC refrigerant), but it's a straightforward 'remove and replace' process once the system is safe. If your AC has lost its charge and you've found the leak, this hose is the part you need to get it blowing ice-cold again. Just double-check your vehicle's exact year and model before ordering.
