Overheats and leaks water

Ford F-150 2008  360000 miles
I have a Ford F150 XL 4WD 5.4L. What happens is that after stoppin for around 10 minutes the water starts leaking, but there is no high temperature indication until it lost around half the water, and then it indicates it's overheating.
Notes:
* I removed the thermostat two monhts ago
* I removed the water pump but it looks in good shape, it might be leaking but very very little, not enough to run out of water in 10 minutes
* It has 200.000 miles
* I can't see any leak in the water hoses
* The readiator doesn't seem clogged
* The water intake is not leaking
* There is no warning light in the dashboard

Check the fan clutch, sometimes they don't work and the engine is not cooled. I have a 2000 model, and when I bought it it was overheating and leaking water the same way as yours

The ideal engine temperature should be somewhere between 195 and 220 degrees. An engine is operating normally when the needle points at the center or near the center of the gauge. Don't worry if the needle does not exactly sit in the middle of the gauge. https://repelisplusdescargar.net/apk

2015 3.5l F150 overheat

Ford F-150 2015  51400 miles
Originally only happened when temperatures were below (-15). Have had thermostat replaced/ system flushed/ New 21psi overflow cap put on. Does not happen when idling only when I get on the highway. Has been in the RED and I hit a bump and immediately drops to normal. (Why I replaced T-stat), but now it still wants to overheat once on the highway, but if while driving I give it some gas it will sometimes stable out to normal temperature. In Alaska and nearest dealership is 100 miles away.

Electric Fan stuck on High

Ford F-150 2014 STX 5.0 4X4 140000 miles
Fan is on high speed, Truck is not overheating, Fan kicks on while driving, started shortly before I had a leak in the upper radiator hose. Fixed the leak, installed new T-Stat, and refilled with 50/50. Radiator fans will kick on after driving for 10 mins or so and will not stop until I shut the truck off.

Fails after starting

Ford F-150 2007  121000 miles
My truck starts normally, but as I'm accelerating it starts failing, the more I accelerate the more it fails, it loses power, the check enging light and a wrench indicator light come on, and while driving uphill it overheats. Please help me!

It could be because of dirty injectors, it might also be the fuel filter that is underneath the driver's seat, check that first to see if it's clogged. If it still fails you should check the fuel pump, it has a filter for the fuel in the tank that goes to the injectors. The stronger the acceleration, the more power it would lose.
