The factory degas cap on the 6.7L Powerstroke is a plastic component exposed to constant heat cycles and pressure. Over time, plastic caps can weaken, lose sealing strength, or fail — leading to coolant loss and inconsistent system pressure.
The Sinister Diesel Coolant Reservoir (Degas) Cap is a direct replacement designed to work with both the OEM plastic coolant tank and Sinister Diesel aluminum coolant reservoirs. CNC machined from solid 6061-T6 billet aluminum and rated at 21 PSI, it helps maintain proper cooling system pressure while eliminating a common factory weak point.
With an integrated pressure relief system and durable anodized finish, this cap is built to perform long term while adding a clean, upgraded look under the hood.
Features:
- CNC Machined 6061-T6 Billet Aluminum – Built from solid billet aluminum for significantly greater durability than the factory plastic cap.
- 21 PSI Pressure Rating – Maintains proper cooling system pressure to support consistent engine temperature control.
- Integrated Pressure Relief System – Internal relief system is engineered to continue functioning even in the event of gasket failure.
- Anodized Sinister Blue Finish – Finished in signature Sinister Blue with a precision laser-etched Sinister Diesel logo.
- Direct Replacement Fit – Designed to replace the factory degas cap and fully compatible with Sinister Diesel aluminum coolant reservoirs.
- 1-Year Warranty – Backed by Sinister Diesel quality and customer support.
