Coolant not circulating

YOU MIGHT HAVE CLOGED RADITOR OR NEED TO REPLACE WATER PUMP.

And make sure the air pockets are bled from the cooling system when re-filling...

agree with rowefast the biggest problem with cars these days is the radiator sits lower compare to older cars therefore anytime u service the coolant u need to bleed the air out of system otherwise it will make u its overheating and some cars takes longer than others..

I am having the same issue with my 2005 5.7 litre. I replaced the thermostat and it is still occurring intermittently. I am inclined to believe the air pocket theory. It could not be the water pump. If the pulley is turning and there are no leaks out of the shaft, then the impeller has to be turning. The only way the pump would not pump would be if it isn't primed.

I have a 2005 Durango. We’ve replaced the fan clutch. It was fine. The water pump. Also fine. The thermostat. Also fine. The lower radiator hose. It was fine. We’ve bled the air. Washed the radiator, flushed the radiator. The vehicle still overheats. Nothing has ever leaked. All of the above things were done as diagnostic repair hopes. Any ideas? It’s not showing any signs of a cracked head either, except the overheating. Any help would be appreciated.

I would recommend you check the air pocket theory again. We cleared up our overheating problem that way. I filled the radiator and overfilled the reservoir and drove it close to home. As it began to climb up on the temperature scale I shut the engine prior to it getting in the red zone. I waited for the radiator to cool and then I could add another half gallon of coolant in the radiator. Problem solved, for about a year now. On another forum another Durango owner said he solved the problem by drilling a 1/16” hole in the thermostat to allow the air pocket to escape. I did not try that but it would have been my next move if the “burp” method had not worked.
