2004 Chrysler 300 OVERHEATS

Timing chain? These people are rip offs. Check/change the radiator cap, and have the engine coolant temp sensor, also verify that the fans are coming on, both when it reaches operating temp and when you turn the a/c on the fan or fans will come on, I'm not sure if this model has one or two fans.

May have an air pocket, however that should have worked its way out within 5 miles. Is it boiling over? (Overheating and coolant comes out from the radiator cap, or expansion tank)? If not, and the gauge is reading hot, may be the temp sensor, however, was there a previous coolant leak? If so, do you know if anyone put in a stop leak? If thats the case, then you need to have your cooling system flushed. Also, you can check to see if your radiator is flowing by simply starting the car (after it sat and cooled down for a few hrs) touch the upper radiator hose, and the lower radiator hose. The only 2 big diameter hoses in the front of the car, if only one heats up, then your radiator is clogged. Get it replaced. If both heat up, then your problem is elsewhere.
