I have a 65 dodge dart and
we just recently put a new radiator but it heats up quick without being opperated. What could be wrong with it?
Take not that everything has been changed to new, the water pump, thermostat and we also got an engine rebuilt.

It's possible one of the new parts may be bad, particularly the water pump or thermostat. BTW, the thermostat should be 180 degrees on a Dart, whether it's summer or winter. But there are three other things that I think are more likely.
One is that the block may have gotten full of rust, scale, etc. If this is the case, you will need to have the cooling system flushed out with some chemicals to remove that. If you already had the block "hot-tanked" when you had the engine rebuilt, though, this probably isn't the case.
Two, do you have the fan shroud still there? This is a plastic thing that surrounds the fan and helps it pull air through the radiator. After 40 years on the road, these things often go missing. A missing or busted fan shroud is especially likely to give you trouble when the car is idling.
Three, your temperature gauge may simply be wrong.
There's a couple other problems that can go wrong. If you have a clutch type fan, make sure that it's not slipping. And check to be sure your ignition timing is set correctly.

Remember sometimes new parts are bad. Also check and make sure that the Thermostat was not installed upside down. Make sure that your water Pump Impeller is turning, Look in the Radiator when you Engine is started and see if water looks to be moving, or not. If not Water Pump is Bad. A clog in the Exhaust can cause overheating. If your Timing is way off that can cause overheating. If your Valves are to tight this can cause overheating. To name a few. Hope this helps.

Ok you say you have a new thermostat? Is it a Summer thermostat or one for Winter? A Summer thermostat is something like 160 degrees..while a Winter one is 190. Check it out. Also if that doesn't help try getting a larger radiator. Has the radiator been flushed? That will help with the heating problem.

What do you mean by "without being operated" ? And you're saying that everything IS new (check spelling)?
Is this occuring at idle or in traffic? One common cause is that the water pump is not moving enough water to go through the engine fast enough at low engine speeds. This is common with so called heavy duty water pumps on Mopars. To check this put the car in neutral and raise the rpms up to 2000-3000 and watch the temp guage. If this is the cause, a smaller diameter pulley on the pump will fix it.

Check to see if the thermostat was put in backwards. If it is, there's no water flow.
