Cooling issues 69 Dart GTS 340

I agree with the posts above.

As far as temperatures. 210* 190 to 210* is normal while driving. Actually pretty good. It means oil temp while driving is also in that range and that's also good. Helps remove condensation and combustion moisture from the oil and the viscoity is in the right range at those temperatures.

As far as dumping coolant when shut down. Yup. Eventually the amount in the radiator when cold will be just enough not to dump when shutting down hot. My recollection is either an inch above the tubes or an inch below the fill neck is about where it should be. I've added an overflow on mine so its been a while since dealing with the drip tube system.

I'm not saying it can't be better or the isn't a problem, but its in the ballpark of what to expect.
