Repair info

That's awesome you chose something dead simple as an argument. Almost as if you don't know how much time proper service info saves.
Now run down a wire that has an intermediate short in it. A proper wiring diagram can save hours, which pays for the service info in one job.

 

Shoot, i don't need no manual. Got it all up in my head...

 

That's why I used this emoji lol

 

I do not see the money as a problem if the service is provided. The outfits I have dealt with like that could not provide the service. It is not a warm fussy feeling after you spend 10 grand and cannot set injector trim codes or get wiring diagrams.
I had a bad Mitchel experience. Thank they were bought out by Snap On. Hope it is better.

 

A place I worked bought a Mitchel subscription. I was not impressed the wiring
diagrams were not close to what the dealers would supply us.

 

Pull the radiator cap, drive a new truck underneath, reinstall radiator cap. Problem solved.

If that doesn't fix the problem, then also replace radiator cap.
