Sonata NF (2006-10) :: Engine Overheating - Temperature Gauge Was Pointing At The Redline
Feb 21, 2011
Car: 2006 sonata GLS V6, 62,000 mi
Abstract of symptom: Delayed cooling fan kicking in
Full Symptom description: 2 weeks ago, I was stuck in slow-going traffic. All of the sudden, I found the engine temperature gauge was pointing at the redline, which had never happened before! Then I was about to make an emergency stop on the shoulder, the gauge was falling back to the midline within 30 seconds. As I kept driving in the traffic, the gauge just fluctuated between mid-high to redline. There was a moment I had to stop and shut the engine down, then 1 minute later I restarted the engine, the gauge turned normal again: a little bit under the midline. Then the traffic improved, and the gauge stayed calm all the way home.
Then I noticed that the overheat problem only happens on slow-going/stop traffic; in another word, when I am driving down the interstate @60 mph, engine temperature is always perfect. (a little bit under the midline) At the parking lot, I triggered the problem to re-occur by idling while I was watching the cooling fan--and I found the fan didn't kick in until gauge hit mid-high. After fan kicked in, the gauge fell back to midline, but seemed never to the perfect status. (a little bit under the midline).
Differential: Coolant quality and quantity are good; no visible leak on radiator/hose; when I started a cold engine in the morning and turned on A/C at the same time, the fan kicked in immediately. And it seems that keeping A/C on can prevent overheat from happening, even in slow-going traffic.

I have had my 1998 Honda Civic for about 5 years now... I bought it used. Occasionally I have noticed my oil levels have been low every 2 months or so. Oil is not being burned and doesn't leak. It hasn't affected performance from what I can tell. I have basically monitored the levels and everything has been fine. There was also an electrical issue since I have had it.
About 8 or 9 months ago, I noticed the temperature gauge was basically in the red while driving. I pulled over and noticed the oil was reading empty. I put oil in it and took it to the shop the next day. They told me the head gasket was bad and that the oil and coolant were mixing and recommended I replace the engine. I asked them how long I could manage before the car quit entirely and he said maybe a month, two if I kept doing oil changes.
I put the heat on while driving it, and the temp was normal. I took it to another shop the same week. They couldn't get it to overheat for a couple hours. The guy told me it was probably the fan but wouldn't know unless he could see it overheat. He said the fan would cause it to overheat at stoplights when there wasn't air on the engine. When the car gets hot, it doesn't get worse at stoplights and is only after I've been driving like 20 minutes that it heats up. I asked that he call me as soon as he knew what it was and I would decide whether I wanted it fixed that day or not. Then I didn't get a call for awhile, and when I called them, they said the guy was out getting the part. I felt like they were rushing so I would replace the fan. I asked if it was the head gasket because I didn't want to fix a fan if the engine needed to be replaced. They said it was not. I didn't replace the fan. They also told my husband that we could save wear and tear on the engine by putting the air conditioning on instead of the heater. When we do this, it overheats. Its only when the heater is on that the temp stays normal.
I have been driving the car for 8 or 9 months now with the heater on with no performance issues. It doesn't overheat and even when I forget to put the heat on it goes up to the red, but doesn't "overheat" with the steam and whatnot. It doesn't seem to do anything to affect the performance of the car. We have replaced the radiator cap, which had pieces falling off, and it didn't work. The check engine light came on yesterday and the code indicated something to do with the transmission.
We took it to a third mechanic today and he said I needed a new thermostat... I do not see any sort of film in the oil. We just flushed the coolant today and there was no sign of oil. I'm totally lost on what to do. I feel like the mechanics have lied to me about what was going on. They contradict each other and the little things they told me don't seem to be the case or don't work.

2005 Hyundai Tiburon Keeps Overheating
I live in Washington State and have a 2005 Hyundai Tiburon with less than 110,000 miles. I have had it for 5 years, and have not had any issues with the car until recently (last 2-3 months). My car overheated on me back in May while out running work related errands. I was able to leave it parked downtown while my husband took a break from his job to come pick me up. Since then, it has continued to overheat every time I drive it.
The temperature gauge climbs into, or dangerously close to, the “red Zone” within the first 10 minutes of driving. The first couple of times the car overheated, if I was using the air conditioner, it would start blowing hot air instead of cold air and the air would stay hot. Now when I drive the car with the air conditioner on and it over heats, it continues to blow cold air (if that matters at all).
My super handy husband (a certified motorcycle mechanic) has done the following in an attempt to fix the car:
•Checked coolant levels
•Topped off coolant
•Bled coolant system and added yet more coolant
•Replaced the thermostat
•Replaced the radiator cap
•Water pump was replaced November 2012 (not even a year old yet)
The radiator cap was the most recent fix. It was replaced on a Wednesday evening after testing it and finding that the existing one was not maintaining the proper PSI. The car drove great around town for two whole days without any issues (Thursday & Friday). Saturday, I decided to take it on a longer drive out of town to see if my good luck would hold…it didn’t. I drove a total of 30 miles round trip and my car started overheating after about 20. I limped back into town and barely made it back to our apartment.
My car continues to overheat!! What is going on?! So confused and frustrated I’m hesitant about taking it to a mechanic who, my husband is convinced, will just charge me to check all of the things he has already fixed.

I have a 2004 Hyundai Accent. The temperature gauge in the car moves toward the "danger zone" only under both the following conditions:
1) Car is at IDLE after being driven for a while (15-20 minutes). 2) Headlights are ON (I've sat in the car and watched the temperature gauge move up and then back down as I turn on and thrn turn off the headlights).
*What I've also noticed is that the temperature gauge starts moving up as the radiator fans kick ON.

I have a '93 Ford Tempo 2.3 liter with a/c ....it OVERHEATS ... love the car, but when I sit in traffic, the temp needle goes up almost to the redline, I have to shut the car off .... it happens all year round ... if I'm driving up a hill the temp starts climbing, if I turn the heat OFF the temp climbs, in summer when I put A/C on the temp climbs ... I've put 3 Thermostats in, a new Water Pump, there are NO leaks in Radiator, I've replaced Hoses ... no I'm not a mechanic, I've brought it to garages ... other than the overheating issue it's a good lil car, uses maybe 1 QT of oil every other month ... when I lived in SC had the same car....SAME PROBLEM...had a 1995 Windstar that did the same thing, replaced radiators etc nobody could figure it out, or didn't want to....what is it with Fords!

When I drive on a hot day the engine overheads; it almost red-lines. This occurs mostly when I drive up long steep hills (I live in the mountains) with the AC on, but even without the AC on very long steep hills (5+ miles) the engine will overheat badly. I can go over a hill and head downhill or flat and things return to normal quickly. I can also drive with the AC on doing 0-80 mph on a flat road and everything is fine all the time.
- Fan is working
- Thermostat has been replaced
- Radiator flushed
- Engine coolant temp sensor replaced
- Heat is working

I have purchased a 2007 Sonata GLS that was involved in a front-end collission. The car has been rebuilt with and now the engines heats with the temperature going up to the red zone when idling after approximately 40 minutes of driving or sitting for 20 minutes or so in very heavy traffic. It is completely fine when driving at about 20-30mph, and even if it came to the red zone and we start driving it, it cools down within a minute or so.
I have read other related threads and tried to read everything that google could find related to this issue. I don't see any blown fuses and or wires not connected / loose. My battery went out yesterday but it had 500 CCA (cold cranking amps when my car needed 600, it was replaced yesterday, just in case it works.
So from my investigation, the only thing I have no clue about is the small fuse box located in the engine compartment in front of the main fuse panel. I am including pictures of it. On the cover, it says that it needs two fuses, both 60A, one for AGCS (Active Geometry Controlled System, I believe) and the other one for COOLING.
So even the dealerships in the area don't know what the box is for or at least that's what they say. All I see inside in the box is two black thick wires and they are connected, not even sure what the fuses are for.

My engine started overheating, and because I was stuck on a bridge during rush hour (George Washington Bridge in NYC), I couldn't get stop the car. I drove it for approximately 30 min (slow crawl), and this happened: [URL] .....
Yes, I know how stupid it is, but there was not even a shoulder to pull over to the side. The only good thing is that this happened pretty much soon as Igot off the bridge, and not on the bridge.
Hose by the radiator cap (is that the overflow hose?) popped out and spewed steam for good 5 minutes. The car did not start at this point. I left the car by the gas station after the bridge, and came back later on in the night. It started and I was able to drive it home (about 10 min away) at crawl speed without it reaching the red zone.
Today, I just did the oil change, topped off on the coolant, and also replaced the thermostat. But the engine still overheats (to the red). The upper radiator hose is burning hot and the bottom radiator hose is not. Also, the fan is working, but it blows out pretty hot air.

After a cold spell this past winter 3 dots appeared on my car's temperature gauge LCD display. The dots are also displayed when the ignition is turned off and a door is opened .

I got my car back finally and on the way down the belt way i started sliding around a big turn and I get home to see my temp gauge way up and all the coolant went all over my engine .
I took it to a shop the did pressure test and that was fine, But the also found jell around the thermostat. The other thing they said is that it had air bubbles in it too. They said exhaust bubbles. But when they ran it it didn't heat up any more. They said its the early stages of blown head gasket ..
I took it to the dealer right away and they are telling me they cant find any thing wrong. Both places asked if i put stop leak in there but I never added anything to my car. So I am lost and don't know what to do.

Just wondering if this is anything to be concerned about. I have a 2006 Saturn Vue. It has just over 80,000 miles on it. The temperature gauge has always registered just below the "second mark" once the car is warm. As of last week, the gauge is now registering slightly past the "second mark." So, higher. It is no where near the "red" zone, and nothing seems to be wrong, but it has me concerned. I took it in for service and they said "it is still well within the normal range, don't worry about it." But I think something made the gauge go higher, and I am concerned about a problem lurking. Am I being a Nervous Nellie? I love my Vue and want to take good care of it.

The temperature gauge in my 2006 S60 2.5 T suddenly stopped working and I noticed that the cooling fan was stuck on relatively cool Michigan weather. In addition I also noticed a 2-3 mpg reduction in average fuel economy and a reduction in overall power. I did a little research and found that the 2006 2.5T models had an ECT recall. Turns out the ECM was telling the engine to operate at overheating conditions,due to a faulty ECT.
Picked up a new Engine Coolant Temperature Sensor (OEM is recommended by most authorities for replacement sensors). I replaced the ECT without even removing the engine cover, it didn't fix the problem at first. Then I pulled the fuse for the ECM, a 5 amp fuse in the box mounted on the drives side fender, and let the ECM reset for a few minutes. Then, had the temp gauge back, and had peak engine performance at operating temperature.

I have a 2006 Jeep Liberty 2wd (V6-3.7L) that is showing an overheat on the temperature gauge on the dashboard. I replaced the radiator (which I noticed had pin hole leaks), the water pump, thermostat, and the temperature gauge sensor. The car is no longer running through coolant, but the temperature gauge on the dash still reads an overheat. I do not have any bubbling when the engine is cool, no white smoke, the fan turns on just fine, a/c and heater work, no visible leaks, equal heat from both rubber hoses to and from the radiator and fluid seems to be passing through them.
There is also no smoke and no weird sounds from the engine. The overheat on the gauge comes after about 10 minutes of operation and happens whether I am driving on the highway or stopped at light.The only thing that causes the temperature gauge to go down to normal is turning on the heater full blast.Is this issue just a short in a wire somewhere? Should I start thinking head gasket? If yes to head gasket, should I use the "sealants" that are out on the market as a temporary fix?

Recently (3 months ago) I had the timing belt, thermostat , water pump changed . Just yesterday I noticed that the engine temperature gauge was all the way to the left and did not seem to be functioning. I do not know if it had been like this for the 3 months since the maintenance work....maybe not. But, the guage is not working.

I have a 2012 Passat 2.0 TDI (140) DSG
Sometimes the engine temperature stays low for an entire drive. Regardless of speed - it has happened while sitting in traffic for hours or while sitting at 70mph.
When this is happening, the engine temperature gauge will go up and down, but never reach 90, and the oil temperature reading fluctuates from around 60 to 80. Also the air into the car doesn't get hot enough, but now we're out of winter that doesn't matter too much.
But then other days it will be 100% fine - it rises up to 90 within 10 minutes of a cold start and stays there the whole day - and the oil temperature sits between 90 and 100.
I've taken it to a couple of VW dealers but obviously it behaves perfectly on those days! I remember reading something about a thermostat that circulates coolant to the DSG box, which can cause these kinds of symptoms?

I have a problem nobody can figure out. My check engine light is on. Took it to Advance to have it scanned; came backwith Code 1226, Brake warning light ground short ( not concerned that at this time); Code P1285, cylinder head over temperature; and P1299, engine overheating (this repeated 4 times).
Now for the symptoms: Truck start and runs good, except with engine light on, runs about 4 miles, then the temperature gauge goes all way up, oil light come on (But oil pressure gauge is OK), Have loss power, and heater has no heat. I shut key off, restart, runs perfect, gauges OK, heater OK.

Resurrecting my 940 TD after it's been sitting for a year and the temperature needle now doesn't rise as the engine warms up. Is there any trouble with sensors on these or should i be concerned about something else? It was working when I stopped using the car.

I have a 2003 Passat and the engine temperature gauge will read 190 normally and then suddenly drop to almost zero, stay there for a while then head back up.
I purchased a temp sensor to replace the old but for the life of me I can seem to locate it. I know it's in the back or rear of the engine somewhere.
BTW, the car has the 1.8 engine.

My sister drives a 2005 Nissan Altima. I am not real familiar with Japanese OEMs but I do most of my own repair work on my car (which currently has issues of its own). What's wrong and how do I go about making the repair...

Since I bought the car I noticed my temperature gauge has never even touched the middle mark on the instrument panel. Is this normal or is my thermostat hung open?

I have never seen any of my other cars do this and I just want to see if this is normal. It happens like clockwork every time I get in the car with a cold engine. I let the car sit while the RPMs are high and as soon as the tach drops I start to drive the car softly. The engine temp gauge reaches normal operating temp in a normal amount of time, it does not just jump to the middle. But after about 1 minute it just starts falling quite quickly, as you can see in the video. It's very predictable - happens every time I drive it so it was easy to catch on video. I don't notice any difference in engine performance. Is this normal for a VW GTI or is something wacky going on?
You can skip to 19-20 seconds in the video to see the needle drop.
