I bought a 1994 ford F-350 that was a Navy truck. The problem is that
I can only get between 10 and 13 MPG (no load).

The truck is in good condition, but it doesn't seem to want to "warm
up". I think the Navy people took the thermostat out. So, that would
make it run rich and kill my MPG, right? I'm in the process of tuning
the truck up, so I will see if the MPG goes up, but the temp gauge
never gets above 1/3.

I also have a Navy Dodge Van that seems to never "warm" up also, both
the Van and the Truck do not pump out really "hot" heat, all of this
points to no thermostat. As soon as it warms up I'll get out there to
check, a follow up question is what temp thermostat should I use in
the F350 ?


Thanks
