Winter operation

I have a 2015 Grand Cherokee. I am from Canada and when I was driving this weekend minus 23 C. I received a message that I was required to bring it in for service DEF issue. The dealer said the Def was frozen and is unsure why. Anyone else have issues using this vehicle in cold weather?

Re: Winter operation

Am also from Canada with an Overland 2015 ecoDiesel. Up to now, I did not have any frozen DEF issue. However, I was teach by dealer NOT filling DEF tank to maximum. He explained that the heating element is not effective/strong enough to heat a full tank during very cold temperature.
Dealer recommand to fill up to half tank maximum.

Re: Winter operation

DEF begins to crystallize and freeze at 12 F (-11 C). My understanding is that the DEF tank is supposed to have a heater that thaws this and keeps it from freezing during start up and operation. If the dealer is finding frozen DEF then that's what he should be looking at.

Re: Winter operation

I have had mine at -26C for several hours and -17 to -20 for days at a time even over night for a week outside at -17 with no DEF issues. I agree with NorthMan that the DEF tank should be only about 1/2 full or less since a full tank is a lot of mass to try to keep from freezing (8 gallons). DEF is 68% water and the DEF fluid will freeze at -11C. In the Winter less is better...in the Summer less is better too since the stuff is also heat sensitive.

It makes you wonder who the genius was that invented the DEF-catalytic system for vehicles that have to work in temperature extremes where the key fluid for the whole low emissions system is sensitive to Summer heat and Winter cold in most of the Norther Hemisphere.

Then the dealer needs to check the heater on thè DEF system.

Re: Winter operation

Does anyone know if the diesel fuel gets heated while the engine is running? I'm running straight #2 with Power Service fuel additive. I keep it in my heated garage and would like to use it this Monday where temps are only going to reach 0F for a high. I don't need to shut it off on my run. Thanks.

Someone with more knowledge should be able to confirm, but what I recall reading is that there is some fuel that flows back from the engine to the tank during normal operation to keep it from gelling while driving.

Re: Winter operation

The diesel supplement to the owners manual says: "A 12 Volt heater built into the fuel filter housing aids in preventing fuel gelling. It is controlled by a built-in thermostat."

I'm guessing that is only when the engine is running.

Winter operation

Fuel filter housing may have water. thats why it's heated more than likely.
