Welll.... I'm not too sure where the problem lies. Pop out the old one and replace with the new one. Follow the wire if you don't know exactly where it's located. Use a flat head screw driver, punch in one side. If you drive a hole in it so much the better. Once out clean the hole with some fine grit sand paper. Use a little rtv sealant and tap in the new one, use a socket that just fits inside the rim. If it's a rubber style replacement it's even easier and you don't need sealant.

If you can't access the old one, leave it and exchange a frost plug in another area that you can reach.

Other options include using an inline heater. They go in the line going into the cab heater. Also you can try a magnetic heater, they attach to the oil pan [as long as the pan is steel].
Good luck,

Richard
