Degas Bottle for 7.3L Powerstroke

Sinister Diesel Releases Degas Bottle for 7.3L Powerstroke

Sinister Diesel releases its new Degas (Coolant Overflow) Bottle for the Ford 1999.5-2003 Powerstroke. It joins Sinister’s Degas bottle for the Ford 6.0L Powerstroke in the company’s line of high performance aftermarket parts. Both Degas bottles are made from 6061 aircraft grade aluminum which is TIG welded and pressure tested for maximum strength. This makes Sinister tanks significantly stronger than factory tanks which are molded from two plastic pieces that are sealed together causing stress, cracking and leaking. In addition, aluminum dissipates heat in the coolant system better than plastic, improving performance and longevity.

Sinister Degas Bottles feature a sight glass for easy level inspection. They are direct, bolt in replacements for stock reservoirs and can be installed with basic tools in less than 30 minutes.

The Degas Bottles are manufactured at Sinister’s Sacramento facility and are available in a raw finish, or powder coated Sinister Blue for added corrosion resistance and a clean look under the hood.
