We had the new one ready to go with pipe tape on it and as soon as we pulled the old one out stuck the new one in. I'd guess we probably lost 4 to 8 ounces of liquid. Before plugging in new heater we topped the radiator off with antifreeze. I'm beginning to think that because we did not start the tractor and let the thermostat open up we had an air pocket. But, after installing and adding antifreeze we did plug in block heater and it for sure worked for at least 3 hours as we did some other maintenance on tractor. In my original post I noted that it worked a second time but I'm really not sure of that because son plugged it in AM and when I got home that evening the block was cold and no heat at all on plug or anywhere else. I probably wrongly assumed that it worked the second time. I'm really beginning to think that there wasn't enough liquid on the electrodes the first time and it shorted out then. On the other hand it seems impossible that the amount of liquid that came out of the hole while changing heaters could cause air pocket. I may try it one more time. Sure appreciate everybody's help.

It will cause it to burn itself up and cause an "open circuit". Sometimes it will be visibly burnt up, but other times it will look perfectly fine but just won't work. Only a few ounces of liquid coming out when you pulled the old one out sounds like something's pretty clogged up to me. All of the coolant in the engine from the level of the plug hole up to the top radiator hose should have tried to come out.   [Reply]  [No Email]
