I told him to do that yesterday, Will. One of the first problems in engine
cooling...pressure pressure pressure. It ain't the temp sensor. They do go
but usually they're one of the last things to go. After all that I've read,
I'd be willing to bet he's got a water pump bearing going, going, gone?
Why? One of his statements was the heater is on but no heat is coming out.
Can't get heat if pump ain't pumping. If it was a pressure loss, you would
still get heat and plenty of it.

<< I just went out and started the truck and let it run for about 10-15
minutes. I removed the radiator cap and stuck a meat thermometer in to
check the temp. The temp is sitting right around 190 degrees which is what
the gauge is showing. I can also see the coolant clearly moving through
the
tube. This tells me that at least the pump is pumping the water, the
t-stat
is opening to allow the flow, and the temp sensor is at least showing the
correct temp right now. Not sure what to check next.

Jason,
Since the truck seems to run hot inconsistently and you are also loosing
coolant with no signs of a leak, have you checked your head gaskets? I know
that sounds odd, but stuff happens. I would take the truck to a shop that
can do a pressure check on the cooling system. They should remove the
radiator cap, use a tool that attaches where the cap was and then pressurize
the system. This will tell if you have a leak somewhere. They can also add
a UV indicator that will fluoresce under a black light if the leak is
external. I know it seems odd that the head gaskets might have already gone
out, but it can happen. When you produce products by the 100,000s something
will go wrong somewhere and always slip by inspection. HTH
