I got the new alternator in yesterday by Chrysler and after them saying the car was running too hot and by replacing it that it will take care of the temp issue and my coolant light issue the light is still on and the car's temp gauge keeps going up to the H range.

Has anyone had their coolant light come on? My coolant level is fine right now. Im thinking maybe a sensor issue, but the i doubt it being the car is still running a bit hot.

Any suggestions? I'm taking it back in today to have them try and figure it out, but we all know about dealerships and their diagnostics

Thought maybe u guys would have some ideas so I can throw their way. Thanks.
