Try changing out the thermostat. Sometimes they will not open all the way and it will cause the vehicle to overheat and not start.

I have 84 ramcharger started fine used for about 1/2 hour plowwing driveway shut off would not restart until cooled off 2nd time it has done this?

Sounds as if the ignition control module is getting hot and not allowing it to restart. Had the same issue with a Dodge b-250 van, except for the plowing part. It would run for about an hour and start sputtering and shut off. After it cooled down, van would start and run great for the same length of time and do it again.

  1. Disconnect the negative battery cable.
  2. Drain the cooling system.
  3. Remove the serpentine belt.
  4. Raise and safely support the vehicle. Remove the right front wheel and lower fender shield.
  5. Remove the water pump pulley.
  6. Remove the five mounting bolts and remove the pump from the engine.
  7. Discard the O-ring. Clean the O-ring sealing surface and inspect the water pump for damage, cracks, seal leaks, and loose or rough turning bearings.

  3. Install the fender shield and wheel. Tighten the wheel lug nuts, in sequence, to 95 ft. lbs. (129 Nm). Lower the vehicle.
  4. Install the serpentine belt.
  5. Refill the cooling system to the correct level with a 50/50 mixture of clean, ethylene glycol antifreeze and water. Bleed the cooling system.
  6. Reconnect the negative battery cable, run the vehicle until the thermostat opens, fill the overflow tank and check for leaks.
  7. Once the vehicle has cooled, recheck the coolant level.

My van (93 dodge caravan)over heats i have changed the thermostat, water pump,hoses and now my mechanic found a cooling fan plug thats bad and he wants me to find the plug(boyh ends) or he can sawder it...

If it overheats when stopped it may be a cooling fan issue,if it overheats on the highway it is not a cooling fan issue,as air flow is coming through the rad at highway speed.Don't bother with soldering 2 ends of a connector,just solder the wires together without the connector.Also,you do not have to have the relay for the cooling fan kept in the fuse box,it can live externally with soldered or wired connections.
Other option,just set the cooling fan to run whenever the key is on.
