Just so you guys might be interested. I also have a Fludyne radiator and yeah the Koyo seems thicker than that. Anyway I ordered a a new replacement radiator cap because I felt that the old Fluidyne radiator cap on mine was leaking already (worn rubber seals or whatever) i.e. there's always some water on the underside of the cap after a hard run. I sourced through Fluidyne's dealer network and found one in Las Vegas where I had a friend get one for me. They sold my friend a STANT / Longacre radiator cap which the dealer said is what all the guys there use when they go to the track on cars equipped with Fluidyne radiators. Interestingly enough, the cap is rated for 25psi and comes with its own pressure relief valve. Haven't tried it yet but will let you know. Cost me 23 US Dollars
