yeah, I will install a new lower hose heater. I've had block heaters fail at really bad times and carry a magnetic heater to but it sorta sucks, not generating good heat. I try to get my diesels tuned where I can start them at -10 without a block heater, sometimes it can't be done. I'd like to hear from someone who has to deal with sub-zero weather on a daily basis like us to see how they fared.
