ABSTRACT:
A vehicle cylinder head coolant passage inspection device and a method for inspecting vehicle cylinder head coolant passages therewith. A device and method of the present invention can be used to detect blockages present within such coolant passages. A device and method of the present invention uses one or more fiber-optic probes that can both emit and receive light. The probe(s) are used with a sensor that can register light reflected by a blockage and received by a probe(s) while in a coolant passage. Reflected light readings registered by the sensor can be used to determine whether a blockage is present.
