    Default Dropped plastic in heat exchanger of Yanmar 2GM20F. What to do?

    When checking the coolant of my Yanmar 2GM20f diesel, after removing the pressure cap, the small 2 inch tip of the cheap plastic antifreeze tester fell off into the reservoir and I can't fish it out. Any suggestions on how to get it out. Would it hurt anything to run the engine with it in there? Thanks.

    Try siphoning all fluid out of heat exchanger or draining exchanger to get a visual, Then you might reach plastic piece with a pair of mechanical fingers
