I have a 18 k Koehler generator on board I can’t seem to find where the pencil zinc is located The only manual on board is general use. Thanks for help in finding this
It is most likely on the heat exchanger. It will be a bronze nut, most likely 9/16". The heat exchanger will be a long round tube with black rubber hoses going to it. Perhaps similar to this https://www.bing.com/images/search?...ger&selectedindex=0&ajaxhist=0&vt=0&eim=1,2,6
Some diesel koler units have no zincs in them to begin with. You need to go to a dealer for these and have them tell you and download a current service manual for you for that model
