It keeps running hot. We changed the thermostat and put a new cap on the radiator. And still is running hot.

Hi Michelleef,

Sorry to here you are having problems with your Charger overheating. On occasion, the part can be bad out of the box, but assuming that they are fine, let's move on from the repairs you have completed already. The next possible culprit is your cooling fans are not coming on. Once you get your car up to operating temperature (halfway between cold and hot), you should be able to hear your electric cooling fans kick on. If you don't, take a look under the hood with the car running. If it is not running this may be your problem. This also manifests when your car tends to overheat faster when sitting verses when moving and air is moving past the engine. So, in short, if the cooling fan doesn't come on it's not helping cool your engine and it needs to be replaced.

Here's an article that explains all about cooling fans, for your convenience:

Cooling fans are also generally easy to remove and replace. I am including a link on a very clear how-to video.

Best of luck to you!

When I cut the A/C on the fans don’t come on but they do come when it starts to run hot. But it don’t come on fast enough and when they do come on it’s very loud like it’s hitting something.

I would pull the cooling fan and see if the blades are damaged and what it is hitting on. You may be able to determine the problem with the car off. Try to spin the fans by hand and see if you are able to tell what they are hitting on. These fans don't have anything to do with the AC. They should only come on when your engine hits a specific temperature.

Well, my husband put some stop leak in the radiator when we first got it he thinks that the fans are bad and the radiator is stopped up because it will do fine as long as you don’t drive too fast or put to much on the motor. We just have no clue what else it could be. Just tired of it running hot on us and been stuck on the road.

Hello,

If I may jump in here, but has anyone inspected the water pump? I understand that on this vehicle it is hard to get to, so, are you experiencing any coolant loss at all?

Thanks,
Alex
