Doc, don't suppose the fuel guage also went to the top at the same time........did it?
When my rig overheated last summer, as soon as the gauge hit the red, truck
started pinging and losing power, and about a minute later, as I was searching
for a place to stop, it started spewing steam out the overflow bottle. I was doing
about 40 - 45 MPH at the time, but on side streets, so frequent stops for lights.
If your rig was truly overheating, you'd feel it, not just see it on the gauge.
I'm with pimp on this one. Sounds like you overheated electrically only.
Get the cheap SunPro temp gauge and replace your stock temp gauge with it for a
while. See if it really does overheat on the freeway.
As for your lower radioator hose collapsing: if it were to happen, pull over as soon
as you see it overheating and pop the hood. Lok at the hose. It'll stay collapsed
for quite a few seconds, at least, after you stop.
And finally, get yourself an infrared thermometer. You can probably get a fairly
cheap one at HF or Sears. Run the motor til it's warmed up, then shoot various
parts of the engine and rad with the thermo. Then get out on the side streets for
a bit, come back and re-shoot. Then, get out on the highway and repeat. This is
the best way to see what's going on.
