What about the blue def in the tank? My tank is 1/2 full. I know that it could freeze but I think 1/2 a tank would be enough for expansion. I could open the cap just in case but should I be concerned?
My truck sets all Summer with whatever DEF that's in the tank when returning to the NW from my Winter Wonderland. Never an issue. You will be fine just disconnect the negative terminals, that's it!!!
I bought a Ctek battery charger/maintainer so using this connected to the truck I don't need to disconnect the negative terminals right? I planned to connect straight up to driver's side battery and let it charge maintain both driver and passenger side batts. I hope this is correct.
