over heating?
On Friday I was pulling out my 58 Caddy from its 4 year resting place on my parents lawn and my truck over heated. Its done this only a couple other times, all of witch were during plowing, I just figured the plow was blocking air flow, this time the plow wan't on. Any suggestions?

Overheating
I would seriously check your Thermostat and replace it.
My Dad's 92' F250 sporatically overheated sometimes and not other times. The problem was there is a copper rig on the outside of the thermostat housing that had broken in one place causing the ring to slide on the thermostat and block the coolant flow sometimes. Usually when the truck cools down and the thermostat closes the ring resets and the next time the truck does not overheat because the ring stays where it is supposed to stay.
This was driving him nuts as clearly the problem was not the radiator, fan clutch or coolant level or a blocked air intake.
Thermostats are cheap and the newer models use a different design that can no longer break. I would give this a shot and see if it solves your overheating problems.

Thanks, I will give that a look see and hopefully its that simple and cheap. I've the truck for three years now and haven't changed that, so its proablly due any way. Is there other common heating problems with these trucks?

Also when the temp gets up the fan clutch should lock up. You'll know if it does because it will roar noticebly. Mine just recently began to fail as I now don't hear the roar of the fan as my temp climbs like I use to hear it.

Use a Ford or IH Thermostat only ... Aftermarket ones don't seem to work well in these motors.
Hows the Fan Hub... Does it sound like a tornado under your hood when it gets hot??

How does the fan clutch know when it's hot enough to lock up?

There is either a bi metal strip or spring on the front center of the fan clutch hub.
Which ever yours has, it opens or closes a valve to control the viscous fluid flow inside the fan clutch.
