2002 Lincoln ls v8 overheating

This is another known LS problem. The ETC code it throws pretty much leads the owner on a very expensive snipe hunt. I've done all the above and at the end of the day (not to mention my bank account) my mechanic proclaims, "It's getting old". The best advice I can give you it to try bleeding the coolant lines one more time.

I ended up draining the hydraulic fan reservoir, refilling with castrol high mileage atf wich has cleaning agents in it then drive for a few miles and repeat several times this process cleans the hydraulic fan actuator wich allows the fan to cycle as the engine temp rises. This seems to have worked for now. But if not, I will do a electric fan conversion. Then sell this bottomless money pit... lesson learned Lincoln is trash.......
