I have a 86 Case 580E that seems to have an original freeze plug heater. Do I drill a hole or punch a hole through it to remove or grab the threads of the electrical connection to dislodge. New ones seem to have a screw/bolt that you loosen. Thanks Bruce
I never did it before but theres some vids on it on utube and some do's & donts. Most of them talk about DONT use a screwdriver cuz it pushs it into the water jacket. My take on it is.. use a screw-in dent puller..??
