I have a 2014 F150 just about ready to roll over 60k. The other day the truck started to overheat for the first time. After taking it to my local shop, they ran a pressure test on the cooling system and found that everything is working as it should, with no leaks and hasn't overheated since. I do notice that after driving the coolant is hanging right around the cold fill line (I was under the impression that it should expand and be higher) is that normal for those trucks to do this? Like I said, the temperature stays right where it needs to be and the heat blows nice and hot. I did have them replace the thermostat with an OEM one since the original one was almost 10 years old. Any advice would be appreciated because I'm genuinely confused. Thanks!
Any advice would be appreciated
a poorly sealing pressure cap can cause coolant loss and exacerbate overheating.
No idea why it would overheat though, unless the pump was failing or you had air in the system. (not impossible, since it was worked on). Can you be more specific about "overheating". Do you know the temp?
Which engine is this?
The truck is also the 5.0L V8. Checked the oil and made sure it wasn't frothy so no head gasket leak, which I wouldn't expect for that kind of mileage. No codes were tripped as far as like a check engine light either. Kind of a weird situation, I'm just puzzled why the coolant is low but doesn't seem to be leaking anywhere. I had the upper radiator hose replaced a couple years ago from a faulty quick connect, but hasn't been any trouble since then.
Interesting I haven't thought of that. The gauge got right to the red line and a message popped up on the dash saying that the temperature was high and to shut the truck off. I let it cool down for an hour or so and after that the drive home was fine. It was about 100 miles and the temp never got to a dangerous point.
I recently posted about how I have a 2014 F150 with the 5.0l and how it keeps randomly overheating. I've had the truck since new and since then it's only recently started overheating after a short time idling. I have had the upper hose seal replaced in the past from a leak I had, and upon taking it to my garage and having the system pressure tested, it yielded no leaks. I went ahead and replaced the thermostat with a new OEM one last week and topped off the coolant and it seemed fine. After idling waiting in a drive thru at about 55 degrees outside, the temp gauge started to hit the red zone and I shut the truck off to avoid any damage. I never heard the fan kick on which struck me as odd. Also, the AC won't blow cold either (just luke warm). I'm puzzled on what the issue could be. Could it be a fan? I usually never heard the fan run on the truck unless it's well into the 90s here in the midwest. Not sure if the AC issue is correlated, but I found that it's odd it fails right when I start having overheating issues. Any help would be greatly appreciated!
