Ram DEF System
Just a heads up to anyone that has a 2013 or newer Ram with DEF system. There is a software update that assists with DEF freeze ups. It is free if you have less than 100k miles. Otherwise, you will be looking at about $300. Ours froze up at minus 13 F in Rock Springs, Wyoming. We were on our way home from Quartzite and the Western Winter Blast. We needed to get home and we’re faced with snow or cold - both four letter words. I was also told it’s less likely to freeze up using the boxed DEF as opposed to the pumped DEF. Just a public service bulletin, but regardless if I planned on driving in below zero weather or not, if I had under 100k miles, I’d get the free software update.
