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.

When the truck warms up and stops, when you try to start it again it takes like 10 seconds before engaging in drive, and in high revolutions there is a thumping between gears. It started happening right after cleaning the radiator.

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

Both my radiator fans run quietly as normal. Sometimes. Other times, after AC kicks in, one of the fans stops and the other one…Seems to me, spins twice as fast. As if it were doing the work if the one shut down as well as it’s initial load. It whines. Any thoughts? And thank you to whom ever offers anything. Thanks.

The truck is losing coolant, and I can't see where it is leaking

Overheating light and fan come on but engine does not seem to be hot. No leakes. Heater work and coolant is good level

I am getting oil in my coolant bottle but no coolant in my engine oil. I replaced the oil cooler and flush everything but it still happens. When flushing the engine nothing but coolant comes out, no oil. Truck runs great, not overheating, no codes. Has new radiator, water pump, thermostat and some hoses. Noticed some hoses getting swollen I guess from the oil. It is a 2017 F150 3.5l ego boost with 132,000 miles on it. Did a head gasket test and the blue changed to a light yellow. Any ideas?

Truck is running hot… I noticed the cooling fans for the radiator aren’t coming on
I went through the fuses and relays and found the jcase 25amp fuse in spot 63 isn’t getting power. Anyone know why? Does that 63 spot only get power when the relay is open maybe? 🤔

Temperature sensor where is located

Truck lost heat towards end of last cold season. This year when I tried the heat, it did heat good for about 3 to 4 days and then it stopped again. I checked the coolant and it doesn’t appear to have any leaks anywhere.

When driving the temp gauge will run inthe normal..., range for about20 minutes then it will spike into the red. Check gauge shows up on the dash. Stop and cycle the key and every thing is good. Used o. B. D. Reader. P1299 is the code that comes up. I changed the temp sensor no change. The engine is not hot I can remove the cap on the coolant jug

Large amount of coolant leaking underneath the front of the truck. What can it be? Water pump, Rad or something else.

Ford F-150 2014 Radiator Fan Always On

Started off just shuddering while driving had fluid in pan changed. Truck trans fluid was getting hot throwing fault codes po68a and p0732 and great wrench code. I remembered radiator stop leak was put in radiator about a year ago so I replaced radiator same issuet. I took it to another transmission place they say they put way too much transmission fluid in truck filled it all the way up with trans fluid. I also had lead plate changed same problem any suggestions what could be the problem. When I drive truck it runs good for 15 min and then it starts to down shift from 5th gear to 1st and then begins to stall out. Any suggestions what could be the cause of the problem

A c started blowing hot air all of a sudden the radiator fans are working the blower motor is working this hot air coming out I charged it a couple months ago to the correct level I thought when I just checked it a few minutes ago the needles in the red

Yellowish froth on my oil cap. And my radiator was always low. I was told I have a blown head gasket so I put in a bottle of Barrs into the radiator.ir seed to help with the coolant levels but froth is still there.

Why is my truck over heating every 5 minutes I keep losing coolant

Running hot ! No leaks! Air not on. Heat not on. New water pump. New thermostat! Still over heat! Y???

Heat works sometimes. Drained all coolant from truck. Flushed all components with garden hose. Replaced thermostat and coolant. Had heat for a while then stopped. Replaced thermostat again. Had heat right away put got cold 3 miles down the road.

Truck is running in the normal heat range. After about 20 min. The temp gauge will spike into the red. I can open the cap on the coolant jug and. It is not hot. I cycle the key and it runs and the gauge is in the normal range and runs there for twenty min. Ichecked with an o. B. D. Reader the code is p1299. Says temp sensor. Ichanged the sensor which is located in the intake behind the alternator no change. Any idea where to check next.

Coolant fan runs very fast even when engine is cold Have tried everything except Freon being low replace Thermostat and water pump Also replace head temperature sensor new antifreeze new radiator or reservoir cap I'm dumbfounded as to what to do

My battery keeps dieing and it's brand new as well as alternator my starter and water pump

How to flush the turbos on a 2017 f150 3.5l? My oil cooler was leaking oil in my coolant.

The radiator fan goes high, dash shows radiator emblem but the gadget says it's cold. Drives fine.

The fan will not work on the heater.

Truck starts overheating about 1/2 mile away after I start driving. Radiator hose swells up bad and a lot of pressure. Replaced thermostat. Checked coolant. And checked head gasket. Still overheating. Need help

I replaced both cams rollers fazers timing chains cam sensors oil pump water pump throttle body throttle body sensors now I’m not getting power to my coils. I have checked all fuses and relays and no codes pop up any ideas?

P2601, where is the fuse for the cab comfort auxiliary coolant pump?

My truck is leaking tons of coolant and my radiator is fine and my water pump seems to be working as it should. I think it’s the head gasket but not seeing any signs. My mechanic screwed me over when he was working on it and when he did an oil change and there was no oil in it not sure what to do.
