Just pull the lower radiator hose off.

My Ranger has a drain on the back side of the lower right hand side of the radiator. It seems your Mazda should too.

Yup, there's got to be one there, and the usual place is the engine side of the radiator, passenger side bottom corner. It might be hard to see because of the shroud. try looking from underneath.

Be gentle with the drain valve on the radiator. The plastic gets brittle with age and may crack easily.

Ditto. Albeit messy, by far the quickest and most effective way of draining coolant.
