So hello everyone. Ive been driving from south fl to north carolina. Got stuck in jacksonville for 2 days replacing a fused on wheel bearing to to the spindle. Many hours wasted and plenty of money spent on hotels with transportation. I thought my woes were behind me at the point. I made it an entire 70 miles till my engine shut off at 72 mph and i had to man handle the brakes just to slow down. I pop the hood and bam.... There is steam and violent bubbles emerging from my coolant reservoir. I wait for the engine to cool off and fill up the radiator itself and try for a turn of the ignition. The sound it made is equivalent to the sound of a injured dog. It didnt want to turn over and just whelped. My engi​​​​​​ne temp gauge was telling my temperature was perfect the entire time. I am so confused and now stuck in another random town for another random amount of time.

 

It is hard to be specific since we do not know what year your truck is or what engine it has.

However it sounds like you may have a leak in the cooling system, and now a good possibility of a blown head gasket or a cracked cylinder head.

With low coolant your temperature gauge may not work properly.

A coolant temperature sensor is most accurate when submerged in coolant.

At this point all you can do it make sure the engine is completely cool, top off the fluids

Check for water getting mixed in with the engine oil. check for a coolant leak repair as needed unless you find water in the oil.

Hopefully if the engine cools down enough, and your lucky enough the engine may be OK.

I am not sure what else to tell you I doubt your geared up for this type of work or have a place to do it.

 

I assume a 3.0l Vulcan engine but doesn't really matter

Spindle issue is unrelated to current engine issue.

Your description of "engine shutting off" is not clear, did it shut off like you turned the key off or did you start to lose power as engine slowed to a stop and you coasted.
The later, and your description of trying to restart after engine cooled off, is inline with a spun bearing from overheating.
If engine coolant overheats then OIL also overheats, bearings are made of softer metal so if they get too hot they will spin inside the bearing journal, cutting off oil circulation completely to that bearing making it super hot, this friction will cause the crank shaft to slow down and stop.
After it cools down the bearing will have "welded" itself to the journal so starter motor can not turn the engine over.

Temp gauges don't often fail, but that isn't never fail, and as said above, the sender for coolant temp won't read hot if it is reading "air" instead of coolant
