I was removing the radiator in preparation for engine removal, and the damn wire sticking out of the coolant sensor broke. It broke directly on top of the bolt thing so i cant just repair the wire, so do I pick a new one up from mazda or would other autoparts stores carry them too.

 

You can check with auto parts stores. They might have to order it. Chances are you can get it cheaper there than at the dealership. Check at Mazdatrix.com too. They probably have it.
