Sinister Diesel 1994-2016 Powerstroke, Coolant Reservoir (Degas) Cap – SD-DC-FORD-94


Product Highlights:

This new Coolant Reservoir Cap functions like a factory cap, but features custom Sinister Diesel looks. The cap fits OEM or Sinister Diesel 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 gray or Sinister Blue, this cap looks as good as it works!
