replace flat rad cap with pressure cap?
the flat rad cap for a s4 is 17.00 on mazdatrix, can i just use a radiator cap that is rated for the same as the other one instead?

No you can't. Pressure relief caps are only for when the fluid has somewhere to go, i.e. an overflow bottle. Use the correct cap.

Or put a completely flat cap and drop a thermo sensor in there like I did, lol. I don't need to fill from that spot since I can do that on the top of the Fluidyne radiator.

Well I guess I should clarify a bit. If I have drained the entire system, then I do add from that filler neck. If I just need to top off a bit, then it's the top of the radiator. But you are right though, it's a bit more of a pain when it comes down to bleeding the line, but the opportunity to make that plate for my thermo sensor was too good to pass up at the time.

Ive been meaning to ask what people with aftermarket rads do. I just got my koyo in the mail and all of a sudden it dawned on me that I know have a spot for two radiator caps. So does everyone with an aftermarket rad use two caps or what?
