not a good indicator. Not sure on what the starting year is but the block heater after a certain year has a thermostat in the line so it won't turn on above a certain temperature, somewhere around freezing. So checking for continuity may show an open when it is in reality just fine.
I know this is the case on the 2015, and the 2004.5 has no thermostat.
