What if it Snows?

I never run a apu ona truck before so i must ask when it is below zero should i keep the truck running or can i run the apu , my fuel is treated by im just wondering if it will keep batteries charged up

 

Only every single auto or truck parts store on the planet.

 

Thanks

 

Running the Apu in the cold is a good thing.

Most circulate the coolant back through the big engine which helps keep the big engine less cold and easier to start in the morning, Also less time waiting for defroster to start working. Plus the APU should keep the batteries up and able to start the big engine in the morning.

 

It is 5 below 0 that is why i ask. This is first truck i ever had apu on. And this one does recirculate coolant back thru engine. Just not sure if its to cold to run or if i should idle. Thanks

 

When I ran for system transport they always wanted us to idle the truck instead of run the APU when it was that cold

 

Thank u that is wat im gonna do

 

It really is your choice. APU or Idle, while I would run APU, as most are set up to run coolant to the engine. Still would be a good idea when very cold, like 0 degrees to put something across grill to block off wind or the likes. It will help keep the temp up. The question is can it keep the cab warm enough to get good sleep.

 

Minus 5 is chilly. Do you have a Davco and is it heated. Might want to wrap some thermal drawers around it. That's where you will have your first problem.
If your Davco has a heater element and your Apu charges your batteries your golden. Just make sure you turn your key on for a few minutes prior to starting to let the Davco build heat.
If your not 100 percent sure of any of this, wrap your filter and idle.

 

Did not realize you were in that cold of a spot.

At 5 below I would probably idle the big engine..... It's cheaper to throw some fuel at the issue than the bill to thaw out the truck.
