Thank you for the good explanation Rascal and Jon. A person could get educated
here. I had no idea axles had vents. I still think that gizmo spliced into the
heater hose must be a temp sensor that goes to the instrument panel because it
has a thin electical wire that goes to the firewall. The wire seems too thin
and wiry to be a vacuum hose. The temp sensor near the water pump has 2 wires
I think and is connected to the computer. Where does the temp gauge normally
get its reading from? I figured the truck had 2 water temp sensors, 1 for the
computer and 1 for the guage. But heck, you fellers know better than me. I'm
just a guessin.
Thanks again for your patience and help.
