I bought a 1994 Ram D250 that was a Navy Van. The problem is that I
can only get between 12 and 14 MPG (no load). I think the Navy people
took the thermostat out. So, that would make it run rich (low heat
also) and kill my MPG, right?
I'm in the process of tuning the van up, so I will see if the MPG goes
up, but the temp gauge never gets above 1/3.
As soon as it warms up I'll get out there to check (doesn't look easy
to get too), a follow up question is what temp thermostat should I use
in the D250 ?
