It sounds like the coolant filler neck?
You can buy a brand new one from the Mazda dealer.
It comes with a brand new radiator cap too.

Does yours have a bypass fitting?
If not, I'd recommend getting the FD part, as it's aluminum and will probably outlast the engine itself.

im not sure if it has the bypass fitting but if i went to a junk yard what year mazda could i pull one until i made it to a mazda dealership. and yes it was the filler neck it just rite where they molded the plastic together its barley leaking but im not chancing a car i just spend 3k for and me drive down the road and it breaks open and i overheat it and screw it up worse..

I would not chance a used one.
Used ones have a chance to be leaking.
I had one tiny crack in mines that you cannot see except for the telltale white residue from coolant drying up.

A brand new one is like $50 with cap, I think.
Cheap insurance.
