Hey Denny,
I've been runnin' these Isuzu NPR Diesel trucks, for over 15 years
IIRC something like 5 different flatbed tow trucks, in that span
...& probably "worked with" maybe, 20 others (box trucks)
...& have NEVER had (or even heard of) any issues like this
* A couple of days before "the incident" I heard some "chirping"
...but, just thought it was/maybe the bearing in the water pump "goin' bad" (had to replace a few of these)
...so, I was "keepin' an eye on it"
Also, during this time, I noticed some vapor (or smoke) waft past the truck (while sitting at traffic lights)
...but, again just thought...water pump (or radiator) (also, had to replace a few of these)
But, when I was on the highway (just before the incident) I heard the "chirping" starting to get steady & louder
...& "if" it was the water pump, the procedure it to stop driving before overheating
But, it wasn't the water pump
...&/then, when I got off at that off ramp "ALL HECK STARTED BREAKIN" LOOSE"
Now, I know
