I have a 99durango and it has just started overheating on me. I replaced the thermostat and it still runs about 210 and the water will get lost and suddenly shoots up in temp I even tried to remove thermostat all together and no help.I don't see any leaks for the water and I have replaced the water pump about 4 times in the past it just not acting the same. Any suggestions? I've been told possibly the clutch on the water pump to freeze plugs blowing out.

i will move this for you this time

get an infrared thermometer and check the radiator for hot spots should be a nice even gradiant

 

Is your clutch fan engaging? It could be toasted if it isnt the rad. Sounds like a friggin wind tunnel when its engaged.
