TowPro... Crossfork PA... Brings back memories. I used to go down there to hunt deer with a Bow and Arrow and fish Brookies in some little tributary streams. Late 1950's
B. G. Smith... You are right, my thermostat is bad and my serial number is below what you posted. Being aware of this I carry one with me.
When I tested the bug screen I thought maybe I ought to see what happens on the gauges with the overdrive off. On cruise control at 2500 rpm's EGT's dropped almost 200 degree's. Don't remember the boost because I had glanced at the engine temp. It was climbing so fast I could watch it move. Just before it hit 225 I put it back in overdrive. Thats the thermostat, but, then I looked at the trans temp and it had gone from 175 to 185 and climbing, so I will run in overdrive. Wind was bad, it was taking 10 pounds of boost to run on the level.
Jumbo Jet... When I am on a trip I check my oil every morning and sweep the screen clean with a whisp broom I keep under the front seat. Seems that over night those bugs dry out completely.
illflem... I have never heard my fan. I don't think it has worked since day one.
