What'd really be nice is if car/truck owners would support the parts stores who have knowledgeable counter staff so they could afford to keep them in their employ.
Where I live all of the really knowledgable guys either quit or retired 5-10 years ago, so now I just find out what's right myself and go tell the pimple-faced counter people how to get what I need. It's a sad state of affairs.

Tell your uncle it's like Nalcool, if he's been around trucks, he should know that name. Napacool is napa's version.

yea they said it was, i kinda think that my dads 7.3 may be on the edge of cavitating, we have owned it for a few years, but the people before us had it since it was new, well after i flushed the coolant out of that thing i swear it was what come in it from the factory it was the rustiest stuff i have ever saw, and i bet i wasted 100 gallon of water flushing that thing, and one time about a year ago i went and cranked it, well it turned over one time and it locked up like it was hydrolock, well i kept playing with it and it turned over finally made a kinda knocking sound alittle bit missed a little and never done it again so idk, but i bought me a 6.9 now, and there no telling when his will lay down

Is it loosing coolant.
Deopending on where the hole in the cylinder is, the coolant may be on top of the piston or go straight into the oil pan.
The engine will only hydrolock when coolant is on top of the piston.
And if you just bump the starter or if the engine sits long enough the coolant will leak down to the oil pan and the engine will run normally.
If the cavitation hole is low in the cylinder you may not even see compression in the radiator.
