Some block heaters screw in - some have a machine screw that pulls a flat bar or arms to hold it in place. There is a rubber gasket or O ring that makes it watertight. http://www.warehouseautoparts.com/Specialty_Line/Kat/images/Kat's%20 _10435-04.JPG
I think one was made that went in heater hose and slowly pumped warm water round. more positive!
There's many different types of heaters. Some are non invasive like the dip stick heater or the stick on oil pan heater. Others go in a coolant line like Jimmy pointed out. There's even car battery heaters to get more cranking amps. --- The downside of a block heater is that they eventually corrode and leak after ten years or so..
