Ive found the problem to my cooling issue, thank god its not my coolant seals.

any who it seems to be part of the " idle air control system" right between the intake system and throttle body, lmk if you know the proper name of the part and where i could possibly find a new one, thanks!

The BAC valve? Or the thermowax? Do you have a picture of it's relative location, or describe a little better on it's location (or even what it looks like?). Typically you'll have two hoses that run together then plumb through the BAC (two rubber hoses, connected to a solid line attatched to the BAC), and also the thermowax which is attatched directly to the TB.

I would take a picture. you might just need a new rubber line or something

The coolant hoses that attach to the BAC valve can be had from several sources including MazdaTrix.com or, strangely enough, your local Mazda dealer. Download the free parts catalog for your car at the link below for more information.

Thermowax system, it keeps your idle up to 1500? until hot coolant reachs it and pushes a little "cam" that allows your throttle to fully rest and your idle to drop to 750. You can remove it and block it off, but i suggested picking a working one up in the parts section of the forum. If you can't get one, i'll look through some manifold and see if i have one thats not stuck... usually they are replaced when they stick, i've not seen one yet that leaked, maybe just the gasket underneith?

In your pic by the throttle cable is a plastic piece which is an off yellow in color. This is called the "thermovalve." Do you see the two small hoses which connects to it from the underside? It "appears" there is "fluid" where the hose connects to the thermovalve. I have an automatic and the thermovalve has three hoses connected to it as opposed to the two which your model has but on my auto the hoses are "vacuum hoses," thus there should not be any fluid in them. If this is the case then the thermovalve appears to be shot and needs replacement.
