What is the DEF gauge?
Diesel Exhaust Fluid (DEF) Making sure you do not run out of DEF in a SCR equipped truck is simple – watch the DEF gauge, which is part of the diesel fuel gauge, for when it is time to refill. DEF is stored in a dedicated tank next to the fuel tank on the driver’s side.
Why is Def gauge almost empty after filling up?
They reset by removing the battery cables and reattaching, topped off the DEF tank and think they may have reset the computer and it now seems to work great, DEF shows full… Click to expand… Thanks for the update, jetpilotchris1.
Is the Def Guage on a Dodge Ram bad?
They are not bad. They still work. Hell of a lot better than other that don’t have a gauge at all so you don’t have a clue until the DEF light comes on and you have a limited number of miles to travel or a limited number of starts before limp mode. In your case almost a jug of DEF represents less than half the capacity of the DEF tank.
When to add 5 gallons to the Def Guage?
Drive your truck until the 200 mile warning comes on, then add 5 gallons. The gauge is notoriously inaccurate, even in the best of conditions. It isn’t actually a gauge, so much as a wild guess… just like the oil pressure gauge isn’t a gauge, its a guess based upon operating conditions.
Why is DEF tank showing almost empty after oil change?
First oil change at 7,000 miles on a 2017 6.7 had dealer fill up DEF tank which was showing almost empty, showed full on gauge until 2 days later now it shows almost empty. Topped off DEF tank and it was full.
What should I do if my Def gauge is not working?
I too like to leave the DEF tank at less than 1/2 full when it gets cold to give the heater a fighting chance to do its thing. That’s assuming, of course, that the DEF gauge is actually working. If it’s in the shop, drain the tank out completely to see if it changes.

What does it mean when your Def gauge says 32F?
DEF freezes at 12F, not 32F…so it doesn’t have to be as warm to get it unfrozen. Its only a 5 gallon tan. I would imagine a few hours would unthaw it fairly easily. All that means to me is that it starts thawing out “20 degrees sooner”. A frozen chunk of liquid tends to stay frozen a long time, in my experience.
