This new Coolant Reservoir (Degas) Cap functions like a factory cap but with a Sinister Twist. The cap will fit Sinister Coolant Reservoirs for 1994-2016 Powerstroke engines. 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. Available in Sinister Blue, this cap looks as good as it works!
