My dakota is recently overheating since i installed a new thermostat, it ran perfect all summer without a thermostat, i replaced the radiator, water pump and all of the hoses, when my heater is blowing hot air the truck does not overheat,but as i am driving the blower all of a sudden starts blowing cold air and then my engine overheats very rapidly, i tried replacing the thermostat twice allready but i have the same problem. I NEED HELP PLEASE!!
It almost sound like you have the thermostat in upside down
Or a big air bubble in the system from when he changed everything out. The truck may need a burping :)
Roy and Tom already gave the probable reasons.
Many people here in Arizona remove the thermostat during the summer thinking it isn't needed. I tend to think thats a bad idea and others will hopefully concur.
I concur.

There is no thinking about it. Removing the thermostat is a very bad idea.

Why would they remove the thermostat in the summer??? If the motor does not come up to proper temperature it does not run efficiency??? Just wondering why this done??? Seem like a lot of extra work for nothing to me?? Lorne
Probably air in the system. Not a big deal, but can be a pain. Take the thermostat out, and drill a small hole in the plate - 1/8" or 3/16". Refill the syetem, making sure that the filler neck is the highest point in the system. Make sure the overflow tank is filled with the appropriate amount of fluid. That should take care of it.
sorry to hear your problem but you tell me how you removed the rad fan having a real problem removing mine
