Sinister Diesel releases its new Degas (Coolant Overflow) Bottle for the Ford 2003-2007 6.0L Powerstroke. This component is made from 6061 aircraft grade aluminum which is TIG welded and pressure tested for maximum strength. This makes Sinister’s tank significantly stronger than factory tanks which are molded from two plastic pieces which 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’s Degas Bottle features a sight glass for easy level inspection. It is a direct, bolt in replacement for stock reservoirs and can be installed with basic tools in less than 30 minutes.
This Degas Bottle is manufactured at Sinister’s Sacramento facility and is available in a raw finish, or powder coated Sinister Blue for added corrosion resistance and a clean look under the hood.
