DEF Tank Size?

[Roaminglost]

Does anyone know the DEF tank size?

All I could find was older trucks were 8 gallons. Is it the same?

I "think" it is around 5 or 5.1 gallons, maybe someone that knows for sure will chime in.

5.14 gallons on tradesman and rebel and 5.74 on all other models.

I have a 2020 bighorn ORP and the owner manual states the DEF tank is 8 gallons.

Is that in your owners manual? Mine only goes to page 333.

I have a 2020 BigHorn with ORP and the manual says 5.7 gallons. I can confirm that at a half-tank, my dealer put a 2.5 gallon jug in and the needle went to full.

Yes sir, in the manual.

I must have a old manual or something.

You have to order the "owners manual" it almost 900 pages. You just have a shorten version that comes in the truck. Should be a 1-800 number on that and specify you want the "DT" one. I did for mine and they still sent the "DS" version. Took them 3 times to get it right.
