I have an 06 Magnum RT. I just replaced the Thermostat, again, and I'm noticing two things.

1. My temp gauge on the dash doesn't move.
2. My heater doesn't pump out hot air.


Any suggestions?

Where is the temp sensor and how hard is that to do on my own?

 

Why did you replaced T-Stat, and Did you bleed the cooling system properly?
