When I'm driving and have my A/C on when I'm idling my car starts to overheat. If I turn off the A/C the temperature goes back down . Put a new thermostat and and a new fan.

Hello, I'm Danny.

Just a quick question first, have you noticed if the electric fans come on? I remember Ford/Lincoln/Mercury had an issue awhile back with the fan relay/module failing causing the fans to not come on. Hope to hear back from you soon.Hope this helps and thanks for using 2CarPros.

Hello again.

Yes, that is a possibility. I've attached a picture below of what it looks like. It will be located in a coolant passage.I'll look for a location picture.Thanks again for using 2CarPros.

Hello again.

Are you sure your Crown Vic is a 2011 model year? I've attached a picture below of a 2001 in case you entered the wrong year. Can you double check the model year and get back to me? Hope this helps and thanks again for using 2CarPros.
