On cold nights when I turn on the motor so it won't freeze it stops and makes a coarse noise. It nevers does this unless it is freezing outside. I can kill the power then turn it back on and it agains begins to run and repeats the noise while stopped. I'm guessing the anti freeze system is trying to kick in and is causing an issue but I'm not sure why since it is already running. This requires me to wrap everyting in blankets since it won't run. Ideas please? Thanks!
