The model after mine has the buzzer and fitting for the sensor. I ain't got nuttin' to fit a sensor to the cylinder or block.<br /><br />I know the usual place for temp sensor is in block or head, on cars anyway, but could I fit an inline sensor in the rubber tube on the outlet side of the cylinders? Or won't it work because the water flow isn't enough to give a steady reading?<br /><br />Probably doesn't matter if reading isn't correct temp. I just want to know if it goes up beyond whatever is established as the normal range.
