The moment I waited all weekend for. it was 10 or 11 degrees when I did this, but it sat through the entire snow storm. block heater has never been plugged in, this was pure glow plug action here. 1990 Ford F-350 crew cab dually, 7.3 International IDI under the hood. Merry Christmas everyone, and happy new year.<br />...<br /><a href="https://www.youtube.com/watch?v=lBJaquFBuXU" target="_blank" rel="nofollow">https://www.youtube.com/watch?v=lBJaquFBuXU</a>
