I have the car listed above with a 4.6 Northstar. I have no coolant leaks but temperature gets a little high my cooling fans aren't coming on and also when I take off radiator cap the antifreeze is just sitting. I don't see any flow i am assuming it's thermostat just not sure. I can't seem to find any how to videos on this model. also I have been having this car 12 years but it has been sitting up for 6.

I also attached a wiring diagram for the fans for you if they still do not work.
