Is the truck dirt cheap, as in $1000 or something that you are interested in it? I would expect to have to replace the engine soon... And IP not working, do not count on it being something "simple", if nothing on it works, as that is pretty unusual...

I was driving on the highway when one of the rad hoses rubbed against the fan, and lost all the coolant. I didn't notice until I got to my destination (about 15 min), but the temp went up, but the engine didn't shut down or report any warning. It was a cold day (-25C) which probably helped, but I would expect if the engine overheats until it shuts down, the engine needs, or will soon need, a bunch of fixing.

I'm not saying don't buy it, but expect to replace the motor (say, with a used engine from a wrecked truck), and to have to spend some time finding wiring problems (if you're lucky, just swapping in a another IP will work, with whatever random mileage that IP has).

 

Does it start and run? If it does you should be okay. In general the worst thing that happens is you need to have the heads rebuilt. Plan on spending $200-$300 fora rebuilt cluster. I fixed one but was not able to fix another.

 

It will run until it grenades... Find a better truck unless this one is free or close to it.

 

If it shut off due to overheating, then I wouldn't even bother. Unless it's free or under $1k. Damage is done, but it may still run for a while depending just how bad.
