Brief

Donut's demo (published 2026-07-28) converts a Cadillac Escalade into the 'Icecalade' by installing a commercial air-conditioning unit and a custom ICT Billet compressor mount to push cabin temperatures far below stock A/C. GMC provided a Sierra Denali 1500 to tow the vehicle for desert testing; the episode walks through parts, installation steps, and performance testing and is sponsored by Premium Guard.

Why it matters

On 2026-07-28 Donut converted a Cadillac Escalade into the 'Icecalade' by installing a commercial air-conditioning unit to achieve cabin temperatures much colder than factory car A/C.

Key details

  • ICT Billet fabricated the custom compressor mount for the build, and GMC lent an iced-out Sierra Denali 1500 to tow the Icecalade during desert testing.
  • The episode is a hands-on demo/tutorial on parts, installation, and testing, sponsored by Premium Guard; video published on Donut (YouTube) at https://www.youtube.com/watch?v=FWSoql7Jy4Q.

We found out how cold you can make a car’s air conditioner by installing a commercial AC unit in our Escalade, because car A/C isn’t cold enough and the world is getting hotter.

Thank you to ICT Billet for the beautiful compressor mount! ictbillet.com

Huge thank you to GMC for letting us borrow their iced out Sierra Denali 1500 to tow our Icecalade through the desert.
