Sinister Diesel Coolant Reservoir (Degas) Cap for 2001-2016 GM Duramax 6.6L
This new Coolant Reservoir (Degas) Cap functions like a factory cap, but features custom Sinister Diesel looks. The cap fits OEM or Sinister Diesel Coolant Reservoir for the 2001-2016 GM Duramax. It is made from CNC machined, solid billet T6-6061 aluminum with an interior pressure relief system, so it will continue to function even in case of a gasket failure.
