The resulting separation causes the oil to remain primarily at the surface of the first few chambers, whereas the coolant continues along through the separator until it achieves a state whereby it is substantially uncontaminated by oil so that {HEAD ~ the uncontaminated coolant} may be recycled back into {TAIL ~ coolant tanks} of the machine
