Serpentine belts were cut

How did rpm get to high??
How high was the rpm?

 

If dealer finds you over RPM the motor for extended period of time. It will void any warranty the truck may have.

I witnessed a 2017 kw day cab with a blown motor from over rev of RPM. Going north on 99 down grapevine.

Dealer plugged in and owner has to replace motor at his cost. Driver was fired the day it dropped in the dealer lot.

 

^^^^^^^^^^^^^^^^^^^^
Over rev uphill??? That's odd.

 

Is this japanese Haiku?
Is this problem fix?
How much was new belt?
Your title misleads it does?
Did you get scared on many lights?
How did you make dealer on bricked engine?

Next time something like that happens make sure you have the exact factory spare (Or two) and just enough tool to move a bolt or two, loosen a idler wheel enough to get the new one installed correctly (And assuming this is surpetine belt. Snake it correctly on all of the wheels to be driven or idled under the correct pressure. Go straight to the next dealership asap to have them professionals finish up your work, save the entire engine and hand you a new spare belt for next time.

 

That is indeed odd.
No belt, no go.
No rev no roll.
Write BS, get caught or called out.
I hope BS Not from OP here.

 

Down Hill

 

Yep! It's a true fact.

 

But no jakes?
No brakes?
What gives?
DD15 engines can maintain on the grapevine going down at 110000 gross.

 

Yeah, I have no idea what the hell he was doing. Wasn't there and glad of it cause I don't care to be used as a crash test dummy.
