F250 Cold weather starting
Hello, I am new to this forum. I have a 2002 F250 7.3 disel, When the temp drops below 20-15 F i Can't get it started. Charging system is good, Glow plugs seem good. It starts fine when the temp is higher. I am going to put a block heater in, the kind that goes into the freezer plug. Will this solve the problem?
