Why do trucks fail on an uphill climb?

I worry about having braille on the drive through atm, who uses it?

 

That one weighs heavy on my mind too

 

When you get in a hard pull it strains everything, if your grossing 80,000 lbs the weak spot will fail. Some trucks have well over 500,000 miles on them.

 

I've noticed the grills get smaller and smaller on every design update of most trucks. Probably hard to keep everything cool that way.

 

The biggest reason trucks stop on hills is overheating. The newer trucks suggest to run low rpms to save fuel, but when pulling a hill, it is best to shift down a gear so the engine can run higher rpms, which lets the water pump and oil pump circulate more and helps keep the engine cooler.

 

Miss a gear, can’t get it in the hole until truck stops.

 

So what are you inclined to?

You are driving by a truck that is stopped on the side of the road and you notice... what?
You mistake, what reservoir for something else? When there is not one for the transmission?

You don't see anything as you are driving by, so what is your deal here?


Before I go up a hill or as I am going up a hill, I am not worrying about anything.
If something breaks I pull over and stop... simple.

Going down a hill however, that is something else.

 

Sometimes, with a proper pre-trip, a driver can identify a problem.

But there are times that something just breaks and stops the truck dead in its tracks.
I had that happen when a coolant line to the DEF tank broke just as I crested a hill.
My engine simply shut down as I was going down the hill.
No more power brakes or power steering, I was just shut down and ballistic because of the 'safety features' in the truck.

It is not something that is visible doing a pre-trip inspection, and not even included in the inspection.
