I recently rebuilt my motor in my 94 RX-7 and now im having problem with my "radiator cap area" (only 15 still learning the parts lol), I thought it was the cap so i bought a new one from autozone. (still have leaks), I have the ("thing that sucks up water (the resevoir bottle")... so I put that back on because I had it closed up because it wouldnt suck up the water from it but it (still has leaks) but when I look at my dad's engine his is aluminum and it attached together where it doesnt leaks and mines a plastic piece that has 2 bolts attached to it. So I was wondering where I can buy one of these and I think that'll solve my leakage because it looks beat up inside. heres some pics (sorry if my engine is dirty it just rain/snowed and wind is kickin hard so alot of dirty stuff is on it.....)

You can purchase the aluminum piece at the local Mazda dealership for a few dollars, as well as the o-ring that seals it to the water pump housing.

I think you want part # N323-15-17Y0 but best to check with the parts counter person.

I think the sucking part you are referring to is the AST... Make sure you install that.

If you are having issues with coolant leaks, do a coolant system pressure test. You can rent the coolant/radiator system pressure tester from Autozone and other local auto parts stores.
