I'm relatively new to diesels. I have a 2020 3500 with the 6.7. It got down to about 1F here a few days ago and the truck won't start. I know now that I should have used an additive and I certainly will next time. My issue now is getting the truck running. The truck says to service the fuel filters so I assume the filters have thick waxing fuel all over them. Now that the temp is around 40F, can I out some heat on the filters with a heat gun and get things going? Or am I going to have to replace the filters? Any help is appreciated.
