Dodge Durango Overheating (Temperature Gauge Reads High)


Why is my Dodge Durango overheating and how do I fix the problem? My Durango temperature gauge says the engine is running too hot. The high engine temperature happens on warm sunny days and even when it is cold outside.

The gauge is measuring a high degree of heat coming from the engine. The temperature gauge reads 250 degrees which I am told is too hot and considered to be a point at which the vehicle is overheating.

What are some of the reasons why a Dodge Durango overheats? And for reference, My Dodge Durango is a 2004 with a 4.7 liter V8 engine.

    There are many reasons why your Dodge Durango could be overeating, but it often means something is wrong with the cooling system i.e. radiator fan faulty, corroded radiator core, blown cylinder head gasket or low coolant level.

    I have attached the troubleshooting guide for your model/year Dodge Durango. It lists the most common possible causes for a Dodge Durango to overheat.

    Before you use the troubleshooting guide be certain the engine oil level is sufficient. An insufficient amount of motor oil will cause the engine to overheat.

    It would be easier to diagnose your overheating problem if you provided us with more information. Do you smell coolant? It has a very distinct smell? Have you checked the coolant level? Do you see any leakage coming from any hoses or radiator cap?

    Also, if you figure out what is wrong please update your post. Thanks.

    I just had the same problem. My Dodge Durango was overheating and I could smell the coolant. I popped the engine hood and noticed the radiator cap seal went bad. This is the 3rd radiator cap that has failed on me within in 3 years.

    It’s as if they engineer the radiator cap to malfunction after one year so that you buy another. Just an important tip…don’t remove the radiator cap if the engine is hot as the water/coolant will be pressurized.

    I seen someone get 3rd degree burns from radiator fluid.


    My 2004 Dodge Durango 4.7L was overheating and a little red alarm would illuminate on the dashboard. I spent the next 3 weeks trying to figure out the problem.

    I replaced the radiator cap, I installed a new 195 degree thermostat, which by the way is located on the bottom radiator hose. But still it overheated. I called a mechanic and he said they would need to pressure test it to see if it has a cracked head or block.

    Then my neighbor, who is a mechanic, took a look at my Durango when it was running hot and said the fan blade was not turning on. So I replace the clutch fan it everything works perfect again.
