At what temperature do you leave the truck running?

Depending on the orientation of the brake shoes it's not a bad idea to gently rock the truck in reverse too just to help pop any stuck shoes loose.

 

Let those tires cool off before parking.

 

Think it was 1989, heading to Massachusetts to deliver in Pops 1978 W900A, Cummins / 13 spd / torsion bar suspension. Stopped at a Truckstop in Connecticut and not thinking set the brakes and walked in.

Came out and the trailer brakes had froze up. Another driver happened by and seen I was having problems. He had some air brake antifreeze he gave me. Not long I was rolling, as mentioned earlier just set the tractor brakes. Carried some antifreeze with me at all times after that.

Miss that old truck sometimes, it was a good looking ride. He eventually stretched it and added a bigger Aerodyne sleeper and sold it…

 

For my 3406es, 20 degrees f.

Leaving the truck running on older trucks also keeps the fuel in the tanks warm, newer trucks dont bypass anywhere near as much back to the tanks as the old ones , so having cold treated fuel is also extremely important on them.


Thought i had gelling filters last week... loosing power but never completely choked itself out, turns out i just needed a filter change (probably a little too long between changes), not a hint of gelling when i changed them at 0 degrees despite the previous night not idling. when i started her up it was way rougher than i like

 

10 and below I idle.

 

If you turn off the engine it might not restart. That a big problem and not something you will fix quickly. If fuel gels you going to wish you let idle all night. You got probably 30 minutes till inside truck start to get cold. It will probably be couple hours till road service truck show up if you lucky to even find someone willing to come out and help you.

I don’t understand why people would take the risk. If it company truck they put some idle limit that’s on them. The new engines start better on cold but it was always more of fuel gelling problem plus if you are running thicker oil still.
