ABSTRACT:
A telltale mechanism is provided with a valve that allows it to perform a dual function of providing a visual indicator of the operation of the cooling system of an engine and relieving water pressure within the cooling jacket of the engine. The valve provides a first fluid path through which a telltale stream is intended to flow and a second fluid path through which a pressure relief water stream is allowed to flow to maintain the pressure within the water jacket of an engine to a magnitude below a predetermined threshold.
