  • Thanks, let's get started.

Does this occur more so when idling in park, stuck in traffic, or highway driving?

Ask Your Own Dodge Question
Customer reply replied 11 months ago
Idling in park, Driving stays almost always 199 degrees. Idling with the AC ON temperature slowly rises. Over the course of 20 mins or so I will be at 230 degrees. That would be about 3/4 mark on my temp gauge.
Dodge Mechanic: Chris (aka-Moose), Technician replied 11 months ago

Are there any air shrouds around all the coolers up front that are missing?

Are the condenser fins clogged or bent restricting air flow?

So I gather this only occurs when idling form your response?

Customer reply replied 11 months ago
All shrouds are there. The condenser is good and clean. The Durango has that split radiator and condenser. So the condenser is not in front of the radiator. It's off to the driver side. But yes it will only start to creep up on the gauge when just sitting for prolonged times.
Dodge Mechanic: Chris (aka-Moose), Technician replied 11 months ago

What is the ambient air temp during this test?

When driving with the AC on, how high does the coolant temp get?

Ask Your Own Dodge Question
Customer reply replied 11 months ago
The temp outside is usually around 108 degrees. When driving with the AC on it's at 199 degrees almost always.
Dodge Mechanic: Chris (aka-Moose), Technician replied 11 months ago

Based on the fact it is just sitting at idle not being driven with air flow and the outside temp is over 100. It is going to be hard for this cooling system to not run hot. Most vehicles with a mechanical fan would too start to run hot in this scenario. If this is a scenario you are going to be in frequently, you may want to invest in a electric auxiliary cooling fan to help move more air. The only thing left to blame would be air getting into the cooling system from head gasket failure though I do not feel in any way that is to blame here.

Now that I have posted a partial or complete answer, you will see you can rate me. The deposit you have already paid is not transferred to me until you rate me. I would like to receive nothing less than 5 star excellent ratings. So if we are not there yet, please reply and let me help more. If you're not pleased, let me know because rating bad does not result in a refund, there are better options. Rating now will not close this post nor prevent replying. Thanks Chris
