Ford F-150 (2009-2014) :: Coolant Temp Start Climbing Until Overheating Warning Popped Up After About 400 Miles?
Mar 26, 2015
Experiencing cooling problems with a truck this new? My 2 month old supercrew 5.0 began over heating on a road trip last week. After about 400 miles of driving I see coolant temp start climbing until the overheating warning popped up. Pulled over, turned engine off, popped the hood and did not notice any obvious signs of overheating. Ended up waiting about 15 minutes, started truck up again, temp gauge reading 1/2.
Get back on the road, within 5 min temp starts climbing again, reaches ~ 3/4 then all of a sudden returns to 1/2. Continue on 10 min later temp gauge climbs from 1/2 to overheating quickly. I pulled over again same situation no obvious signs of overheating, but allow sometime to cool off. Started truck again temp gauge reads 1/2. Continue driving and temp gauge seems possessed, going from 1/2 to 3/4 back to 1/2 to almost overheating as I nursed it to the next dealer that I could find.
Dealer tech was able to mimic the problem and believes that coolant is not flowing properly. Thermostat replaced, water pump pulled and inspected, air bleed out of the system, all with no improvement. Now heads are being pulled/replaced to see if this solves the problem. Its depressing to have my new truck with 2,382 miles sitting under the knife at the dealer.

Truck runs cool when driving around town about 177. Get on the highway and the temp goes to about 195, go up a mountain pass she climbs to about 210 and I feel that If I dont back off the gas the truck will overheat because the temp just keeps climbing. Go down the highway again on a flat stretch of highway and it drops to 195, get into town temp drops to 177 and even lower when i just let the truck idle.
Truck has a brand new 195 thermostat, fan clutch is only a month old, water pump is about 2 years old, this truck has had head gasket issues in the past but every year I put in the bars stuff and have not had a problem with it since, I started doing the bars stuff about 4 years ago. This is the stuff you flush the system first with not the pour in stuff. 1997 f150 4.6l

The other night I passed a car overheating (Subaru) and checked my temp gauge and saw my needle was gradually climbing towards the half mark. This is not normal for my 96 Honda Accord. No lights coming on, so I blasted the heater and needle immediately returned to it's normal position. Filled the coolant, it was low, but the problem remains if the heater isn't turned on to at least 3. This doesn't seem extreme enough to be the thermostat. Could my fan be out?

The truck has been just terrific, mostly used for towing our travel trailer. Earlier this year i developed a leak and lost 3 quarts of oil before I caught it. I would think with 15 quarts in her this shouldn't have been too big a deal. However, I am now experiencing 10-15 degree swings between ECT and EOT. Before I give the particulars, yes, I have had three new thermostats, two Ford and one brand X.
Anyway, coolant temps are 184-200 depending upon load, terrain, etc. At the same time, oil temps run 205-230. There is no oil cooler to get plugged up. She's got 120K on the clock, doesn't burn oil, no disappearing coolant. I am concerned about blowing a head gasket or other serious damage at these temps, but don't have a clue where to start? Yes, the fan does come on, but still this seems plenty hot.

So a couple weeks back I'm on expressway home and I look down and and temp gauge is pegged out overheating I immediately pulled off and shut it down and towed to a buddy of mine's shop he flushed it filled it up w antifreeze and checked for leaks and couldn't find one. I drove it for about a week and got out to for a quick stop , Ex parked on a slight decline and came out to prolly half gallon of coolant on the ground..I limped it to my buddies shop as it was not running hot .. he has checked it out but can't find any leaks, even after having it run 30 or so minutes..

1994 Mercury Villager, driving about 10 miles to work this morning I noticed the temp gauge sitting just under the H at about the 8.5ish mile mark. All driving is on city streets from 25-35mph. When I noticed the temp I turned on the heater hoping to assist with bringing the temperature down. The air coming out was mostly cold occasionally pushing out slightly warm for a few seconds.
I got to work and checked the hoses for a leak, squeezing both the upper and lower hoses they felt empty. I added about 1-2 cups of water to the radiator and it would take no more. Started the car up and the supply hose firmed up while the return hose still felt empty. Left it like that until the end of my shift.
Started the car up and checked for any leaks, all fluids appeared to me to be topped off and I could see no leaks. Started to make the trip home and at about the 7 mile mark the temp gauge drifted out of normal. Turned on the heater and the air came out cold. About a mile later I pulled over and shut the engine off for 15-20 minutes. Started it back up and it was sitting in the normal range again, but only for about a half mile and then it started going back up. I finally got it home with the needle between normal and H, maybe closer to H than that. Opened the hood and checked for any leaks. Noticed some anti freeze had come up through the cap on the reservoir. Checked and it was cracked open around the top. The two hoses on the other hand had pressure and were fairly firm/squishy.
Just checked the oil and around the cap on the valve cover and and the oil just looks a little old. (was told by a friend to look for chocolate milk color).

I just fired up my F and I have all of these warning lights popping up. I had undid the rearview mirror to tighten it, but unplugging and reattaching this is a simple thing. The car sounds fine, but it also won't let me shift out of Park (the Shift Lock is locked).

My 2013 Elantra twice now has almost overheated. About a month ago i had the software patch related to the cooling fan done. Since then, twice the temp almost hit max and the warning light came on. Both times i had driven it in 80 degree weather with 3 short trips to various stores. Both times the air conditioning seemed to stop working and the gauge started to rise to max. The second time i turned off the car and restarted it and everything returned to normal. If it happens again i will check to see if the cooling fan is on. It seems to me that turning it off and on to fix would be a software glitch. The car has 30000 miles on it.

Ok so I recently started noticing my car was overheating and the sensor would go off saying coolant temp hot. So I started by adding coolant that didn't work. I than replaced the thermostat didn't change. I saw the water pump was leaking and changed that but before I did I was driving it home one night and the engine stopped and I barely had control of the car. Now the water pump is new and I don't know what the problem is. I think it's the head gasket ???

Before someone says "normal" I know the low temp light is supposed to come on until the car reaches normal operating temp My problem is really strange and my mechanic and I are both perplexed. I have a 2008 Yaris automatic sedan with 98K miles on it.
The symptoms:
After driving for quite a while (30 minutes or more at times) the low temp light will come on... and sometimes goes right out... and sometimes goes on for a while.
If the check engine light isn't already on - it will eventually go on.
Sometimes with the low temp light is on - it will race the engine (just straight high rev) OR it will pulse the engine (like I am pumping the gas peddle) OR it will not let the car shift into high gear (rare). Remember... all of this happens after the car has been running for while so it warmed up.
What we've tried (over a 4 week period now):
The error code indicates to replace the thermostat - so we've replaced it... twice. We've replaced the actual low temp sensor. We've checked the wiring between the sensors and the computer - wiring does not appear to have a short. Last week we replaced the computer with a used one, but the same problem still exists with a replaced computer...
What the mechanic says now:Might be an air conditioning thing running the fan too long?
Can you really run a fan so long it will drop the car temp back to below the low range operating temperature while driving on a highway? That seems pretty unlikely to me.... If it were just a flickering light, I wouldn't be so concerned... but because it revs the engine (even when I am at a stop light and I have to push the brake harder so it won't start moving) and it sometimes wont shift into high gear... it's concerning from a safety perspective.

Have a 2000 subaru outback 2.5l, automatic, with about 245k, I replaced the thermostat,water pump, the radiator and the car is still overheating. both fans are working. no leaking coolant. Maybe this is related- over heats mostly when driving on the highway. But if a shift the gear to neutral and coast for a minute the shift back to drive the temperature gauge goes down. Whats wrong, running out money fixing the car, but love it driving it in the snow.

Started a while back and comes and goes. Only commonality I have found is the truck needs to be warmed up for it to happen and usually after a few hours of driving. The downshift from 5th or 6th into fourth, at times, produces anywhere from a light to violent clunk, feels like a typical tranny slip. It will do it while in cruise and it will do it if I don't have the cruise on. Can't figure out if it is going to be a tune issue or hardware.
It does it only downshifting into 4th from 5th or 6th, no other downshifting is a problem and usually the 6th to 4th produces the worst results. At highway speeds that is usually a shift from around 2Krpm to just over 3K rpm (6th to 4th) if it is from 5th it is about 2500 to 3K. Start from a stop and go WOT and there are no issues.
Having it in Tow/Haul or not makes no difference as far as I can tell. IT can do it on one hill and the next time be just fine or do it 2-3 hills in a row. After this last trip it will do it at 9K feet or at 60 feet elevation, didn't make a difference there either.
Another issue that may be hurting the computer is the truck originally came with the 235 tires, it now has 285's and the rear is only 3.31. I plan on going with 265's and maybe still a gear change to 3.73's in the future. I usually only notice this on long trips, first was a 1500mile hauling an ATV, second was last week during a 2500 mile empty. Although I have had it do it a few times locally. I figure those bigger tires can't be good especially with that high of a rear for the management system.

My temperature has been randomly dropping, them back to middle, and recently my engine was overheating because I'm guessing the fans didn't turn on, because I'm also guessing, the engine didn't know it was overheating?
Anywho, during my replacement, I made sure to get rid of the pressure, and the car was cold. I tightened the cap again, but when I took the sensor out, all the coolant spewed out.
Now if I understand this correctly, do I have a leak? I figured the leak I had was coming from the temp sensor as it is.
Here's some pictures for those who'd like to see ....

My 94 is suddenly seeing small coolant loss with no apparent leaks, temp goes up on dial now when idling, more frequent white smoke from tailpipe. My wife ran is bone dry of coolant when water pump failed 6 mo ago. Mechanic replaced water pump, timing belt and warned that there could be head damage that may appear in a few months. Is this what I am now seeing or should I start with something else?

I have a 98 Buick Century, with about 250k miles on it. Recently when I first start the car and drive a few miles the temperature gauge keeps rising until it is in the red zone and a warning light comes on. When I pull of to the side of the road after a bit it begins to slowly drop and I can begin to drive again. The gauge will then normally stay a bit above halfway for the remainder of the trip, the gauge has sometimes done a bit of jumping around between 3/4 and half sometimes though. The only work that I have had done on it recently is to have some work done on the ac system.

On a few occasion, usually during cool weather, the engine temperature rises up to 130 C, the coolant overheating warning comes on for a few about a minute or two and then the temperature goes back to normal (90 C.)
The car has 106,000 km. I purchased it last summer from an independent use car dealer. I inquired about the car calling the previous owner. He did mentioned that the only problem he ever experience was that the car overheated on a few occasion during the winter months (cooler weather).
Could it be that the thermostat needs to be replaced?

I have a V8 engine, and I have been getting the coolant overheating warning come on once in a while.
The engine fans go crazy, and the temperature needle on the small round gauge climbs all the way to red then the coolant overheating warning comes on in dash screen.
This can happen right after I turn the car on, or on occasion, it can happen as I am driving around the city.
I stop, switch the car off, and I turn it back on after a minute, and the car is just fine. So, basically, it doesn't seem like the engine coolant is actually overheating, but the fans and warning systems seem to think that they are. The fans are pretty loud, and its noticeable when they go on, and when this happens, I know that the needle will go all the way up and the warning will go off. I also know that if I turn the car off for a minute, and it will be just fine.
The conditions are random for when this happens. So its not when its particularly hot or cold or anything predictable. Could this just be a sticky thermostat? Is it a bad water pump? Bad battery?
The trouble is that now I am afraid I cant take a real drive. Around the city I can just pull over, but I am afraid to take the car two hours out or something.

I was cleaning my passat the other day and I took my air filter out, however I didn't disconnect the wires and hoses on top of the box, I just raised the top cover up and pulled the filter out and cleaned it and checked it and put it back in, I also took out the cabin filter out and cleaned it and put it back in too, then I started the car and took it for a ride and the car started over heating, it keeps giving me STOP CHECK COOLANT warning and the temperature rises all the way to max RED.
I check the coolant level is at level and the radiator fans are spinning, however I noticed the lower hose that goes from reservoir to the radiator is cooler than the other hoses, what could be the problem? The water in the reservoir is hot too, could this be from a faulty thermostat? a sensor? or somewhere I read there is a fuse somewhere in the engine bay? I'm not too familiar with these 1.8t engines, the temp sensor was acting funny before too like sometimes it would go all the way to zero and stay there and go up and go down to zero and then raise, which I think there might be a bad connection or bad sensor.
I forgot to add the car is a 2003 1.8T.

Before I go buy a Bentley manual to dig around, when should my radiator fans kick on. I had the car idling for 10 minutes, no ac or heat on, and my coolant warning light came on, it overheated. It already has a new fan switch in the radiator, and the fuses are good.

After about an hour of driving, the coolant temperature light on my 2010 GTI started blinking. The gauge never showed a temperature higher than the usual 190, including traffic and idling. Having reached my destination, I shut the car off and then back on, happy to see no warning lights at all. One dinner and some three hours later, I started back for home. 20 minutes into the drive, the car sounded three tones and the blinking light came on again.
Like before, the car drove without incident for the rest of the drive, and the light was no longer present once the car had been shut off and then on again. The owner's manual said that the coolant level might be too low, or the temperature too high, but neither of these seem to be the case. The car is equipped with GIAC stage I software and an Audi S3 intercooler.
