Morphology

radiator = radiate (transparent) = radiate + or

A regular instrument/agent noun formed from 'radiate' + '-or', so the meaning 'vehicle or system heat exchanger' is a specific application of the device that emits heat.

Etymology

Radiator comes from the Latin root radius meaning 'ray', the same root you see in radiate. A car radiator carries hot liquid and 'sends out' heat like rays to cool the engine, which is why we use that name.
