Could these frigid temps cause a stop engine light and shutdown?

Yeah I didn’t do that. Thanks for advice.

 

Good to know. Truck hasn’t moved. Had me wondering what could have happened.

 

I used to use alot of that fuel treatment stuff. Like a whole bottle in each tank. Had gelled fuel one morning. Some jacksss had unplugged my hot block heater and plugged in a dead one.
Ten below zero. So much fun.

 

On some it can be faulty low coolant sensor,,if you unplug that sensor it will not shut down…found this with Cummins X15

 

I was blue to get over to truck today. I poured some diesel 911 in in case I had a gel situation. Then I looked at the coolant reservoir and this was it. It is rather low. Could this be a cause?

That's not low.

 

It was actually…a whole gallon low. I filled it and no more lights on the dash. It’s all odd because it wasn’t low when I parked it in Oct

 

cold weather brings out leaks. usually small ones. metal expands or contracts with temperature change. fluid as well

 

also you really should pull the hood open everyday and check fluids. But especially if the truck has been sitting for a long time check your fluids. never know what could happen. oil pan could be empty for various reasons

 

That actully happened to my ram once. Rodent had chewed a some wires that had fallen and shorted against the pan and melted a small hole in it while it was sitting. Lucky it didnt catch fire. But a vehicle sitting for even a few weeks can have issues.
