Aux heater

Searching the 2022 2500/3500 upfitters wiring manual, looking for the schematic for the def tank heating system, I came across this.

 

Never knew it existed. Must have missed it in the OM.

Yup, it's in the 2023 upfitters guide, also.

Well the temperatures out side are a lot colder than +8! It takes about 15 to 30 minutes to get the coolant to kick up over +75 also.

The 6.7 Cummins work truck I have takes maybe 5 miles of driving to hit 200F coolant temps after letting it warm up for 5-10min on high idle.

 

Helps a ton to not run the blower motor at all during warm up, never have the blower motor on high if you want the temps to increase.
