i see on mazdatrix, like 8 other water hoses, should i go ahead and replace all of them? looks like the hoses from the reservoir tank would be hard to get to....

The two for the turbos should be replaced but they are a pia to get to. Inspect the little one under the extension manifold and the one from block to throttle body. Are the spring clips holding the upper rad hose still good?

yeah change the clamps cause if the leak is coming from the end of the hoses, its becuase of the clamps getting heat soaked

Yes, those are the ones I was refering to and also # 13-691A-N3A1.
(Extension manifold = UIM )

There is a rubber o-ring for the water level sensor. Check if you have one and if it's leaking.
