Lexus RX 2004-09 :: RX300 Overheating When Driving Around In Traffic And Going Uphills
Run my lexus around in traffic or up hills the temp gauge goes into the red, leave it running in the driveway it overheats and yes the fans work using the a/c so i know its not the fan motors the wires from both the fans go into a fan computer in the middle of the fans near the top of the radiator.....searched all over for a fan temp switch does it have one?
View 5 RepliesSonata I45 (YF - 2011+) :: Overheating And AC Stops Working When Driving Into Some Traffic
About a year ago I was driving along and ran into some traffic. A few minutes later I noticed the AC stopped working, (it was about 85F out), and then I noticed that the engine temp was getting much warmer. Had never seen this before. The car had about 70k miles on it.
Turned on the heater and was able to get the engine temp down. Immediately took it to my local mechanic, who checked that the compressor was running, but was unwilling to tackle this diagnosis and recommended I take it to the dealer.
Took it to the dealer the next day and they diagnosed a bad compressor which they replaced for $1200. However the very next day after I picked it up the very same thing happened. Engine overheating and the AC turns off.
Pretty disappointed in this - I expected the dealer to be able to fix this, especially for $1200. So I left it with them for a week, and still they were not able to diagnose or duplicate the problem. Asked me to come in when it is happening, but since they are about 30 minutes away and it only happens once in a while I gave up on that.
However, ever since then it will occasionally have the same issue. I can usually resolve it by parking for a while, or by turning on the heater for a while. The AC does work most of the time, but of course this problem usually occurs only on very hot days.
Golf IV R32 :: Slightly Overheating In Traffic?

The fans work... atleast they are both on when i shut off the car...
Golf IV R32 :: Overheating - AC Air Warming Up While In Traffic
A couple weeks ago, I noticed the a/c air warming up while I was in traffic. Later the car started overheating while the a/c was on in traffic, but cooled back to normal as the a/c was switched to econ. As of a few days ago my a/c air is not cold at all anymore, in traffic or moving. And now today, my car overheated in traffic without the a/c on, but returned to normal after I waited out the freeway blockage and drove home when the traffic speed was higher.
I've been reading threads on here for about three hours now and going out to run tests. It appears that neither fan runs on low or high speed. I want to check the fuses, but the fusecard is like reading hieroglyphics. It appears that slot 25 (with a picture of a fan) might be the right one, and after checking it appears intact. Questions:
- Is there a fan fuse? Is it #25? Are there more than one?
- If the fuses aren't the issue, is there something else to rule out before removing the fans for inspection and cleaning or replacement? (controller module, thermostat, relays, etc.?)
Golf IV R32 :: Overheating Not To Extreme Only When Stuck In Traffic
So recently my car has been starting to over heat. not to the extreme but the temp needle is going past the middle. only happens when stuck in traffic but as soon as I start going it goes back down.
As far as iv noticed only thing getting me puzzled is my fans are not running when running and starting to overheat. they run when I shut the car off though. The radiator is less then a year old. fresh oil change and the coolant is fine
Golf IV / Jetta IV :: VR6 Overheating When Get Stuck In Traffic
My 2002 Jetta VR6 is overheating. The car only overheats when the car is not mobile. If I get stuck in straffic or just let it idle it will over heat. What could it be?

I was slightly overheating in traffic, watching the gauge creep up a little. So i bought a new fan, swapped it in this morning, and still no Big Fan.
Fuses on top of the battery are all good. Does this mean my FCM is gone?
Golf IV / Jetta IV :: 2002 - Overheating In Traffic - Fans?
So i have a 2002 1.8t that i got in december. Everything has been great so far untill the other day the car overheated on me in traffic. It was a bit warm out maybe 75-80 degrees. I saw the needle start to climb and then the light went on so i through the heat on full blast and it dropped the needle a bit and turned the light off long enough to pull off the highway. I let it cool down and checked things out. I am not low on fluid, an the fluid was changed within the last year with the vw recommended stuff. The radiator hoses are pressurized so i believe that the pump and thermostat are working. I am thinking it could have something to do with my fans. I tested them in my driveway by supplying them with 12v and the spun perfectly. It only happens when the car is standing still for a period of time. Driving at any speed is fine. Is there some sort of switch that tells the fans to turn on?
View 2 RepliesCivic - Honda :: 2003 - Overheating When Sitting In Traffic
This has been happening intermittently for a little over a year now. When sitting in traffic, my car begins to overheat. I've had two different mechanics look at it - the first swapped out the radiator cap.
The second said my coolant levels were low, but he pressure tested the system and found no leaks. He recommended I check my levels before taking long trips - so this weekend, before driving 380 miles to Phoenix, I checked my levels. They were a bit low, so I topped everything off with coolant and everything was fine on the drive out.
On the drive home, however, stuck in traffic, the car began to overheat. I pulled over and checked the reservoir and it was mostly full of coolant, but I added a little more, let it sit for a while, and then made my way through the traffic and home.
Also, I tested the fan, and it comes on.
Subaru - Outback :: Overheating While In Stop And Go Traffic And When Accelerate
I have a 2000 Subaru Outback with a little over 162,000 miles. About 3 years ago I had the head gaskets replaced. This past March the car started over heating while on the highway driving back to Boston from New Jersey. It has been doing this intermittently since then, and I have had two mechanics look at it.
The first mechanic, who is my beloved mechanic in Maine (where I am originally from), checked the sensors and relays. He even replaced the relays for free, and it still overheated on the way back from Maine to Boston. Needless to say I did not give him enough time to really look at my car to figure out the problem.
I then went to my back up mechanic in Boston, who kept the car for about 4 days. He said there are no leaks and the car did not actually over heat while with him. He had one of his guys drive the car home at night and back to the shop in traffic in the AM, and had it run for hours while on a lift, and on the ground. Still no overheating. However, he did say that the car was eating up coolant, which indicated to him that there might be a head gasket problem.
I was a little upset by this diagnosis because I had them replaced already, and also because I am getting married this summer so this obviously is not the right time to be buying a new car. I should mention that both mechanics looked at my car at the end of August. I have still been driving and watching the coolant.
The car is still randomly overheating but i tend to notice it happen more while in stop and go traffic and when I accelerate. The needle will go all the way up to red, stay there for a few seconds and then slowly creep down. This happened this morning, and I had checked the coolant yesterday and it was full! I checked it again at lunch time to see if it had used all the coolant during rush hour and it was still full. This chain of events seems to keep happening and I constantly check the coolant. Since August I have only had to fill it once. I have also noticed that when I open the radiator cap the coolant is not sitting level like I've been told it should. I've put a decent amount of work into the car and everything else runs perfectly.
Is it possible that this is a pumping or air bubble problem, and not a head gasket?
Passat (B5) :: 2002 - Overheating At Heavy Traffic Or Idle
I have a 2002 1.8t with 90,000 miles on it. I have it serviced for new Timing belt and water pump (metal impeller, according to the shop) 3 months ago at this shop. The overheating problems never went away. The problem is that it overheating at heavy traffic or idle after a while or after heavily drive, but it cools off quickly when I rev up the engine a little bit, or after getting out of traffic again.
I have another shop diagnosed, they first told me the cooling system is leaking and may trapped air inside so they did replace thermostat, coolant housing assembly, flange seal, pipe sealing o-ring. they re-test and turn out there is no coolant flow and suggest that is it the water pump that fail and ask me to go back to the original shop for the Water Pump warranty. Additionally, they flow test radiator and its fine.
I did return the car back to the original shop and they tested and said the heater core is clogged with debris and that would cause the overheating. They asked me to replace the whole heater core that would cost $1500. But I know for the fact that I have heating in the car and it is hot!
Is there any other reason than what have been replaced or tested (thermostat, radiator, air trap, new coolant)? I think it could be the aux cooling fan since its never turn on when overheating, only when AC is turn on, is it supposed to work this way? Spent too much on this car and hopelessly the problems went away but it's not.
Corolla :: 1996 - Overheating - Transmission Slipping In Traffic?
I've been driving a 96 Corolla into the ground for the past 5 or 6 years and recently it's been having overheating issues. It has overheated to the point of steam twice now, and I'm worried at this point I've fried the engine or transmission.
I regularly check the radiator fluids and oil thinking that these would solve the issue, but alas it happened again today ten fold.
While driving home in hot southern california today I first noticed my transmission slipping in traffic. It was slipping when I started moving in stop and go, and settled in once I was going 30 or 40 miles per hour. I had my puppy in the car and was only a few minutes from home so I thought it would be fine, otherwise I would have pulled over immediately.As I got closer the problem got worse to the point where I could no longer shift and move forward. I over revved the engine to get it into a safe spot and it overheated. After waiting 40 minutes I checked on the Transmission fluid (checked unrunning) and it was bone dry. The radiator was full with coolant and oil levels looked good. I put as much transmission fluid as I had in my trunk (not much) back into the car, started it and got the car up the few more blocks I had to go. On the way it was still slipping, at the severity it had to begin with.
My question to you is do you think the transmission is totally shot and I need an overhaul? Or is there some hope that it may have been overheating because it needs a flush/drain and new transmission fluid? The car is at 136k miles and has had a replaced radiator in the past year.

View 6 RepliesKia - Optima :: 2003 2.4L Engine Overheating Occasionally While Stopped In Traffic
Have a 03 Kia Optima with a 2.4L engine with 120K. The car recently started overheating occasionally mainly while stopped in traffic. Both fans are running and as soon as I get rolling, the temp gauge goes down. I've noticed that it only happens while the trans is in gear. if I put it in neutral, the temp will drop to normal.
I replaced the thermostat and radiator cap thinking these may have been contributors. I also replaced the temp sensor because it controls both the gauge & the cooling fan. Both fans operate with the a/c on but the single fan will not come on with a/c off. I tried another pcm from the salvage yard but still get the same operation. My next thought is to install a separate trans cooler to the radiator which is only 2 to 3 years old.
What could be causing this overheating & how can I fix it? When it does over heat, I usually turn the heater on full blast to bring the temp down. Car is in great shape and would like to get it back to normal.
Civic - Honda :: 2004 - Random Overheating In Stop And Go Traffic
I drive a 2004 Honda Civic. About a month ago, my car started to overheat. The next day, I took it into the shop,and they said the thermostat was sticking,and I had a small leak in the radiator. I got a new thermostat, radiator (they did not have anyone to repair), and flushed the system.
A few days later, the car started to overheat again, and quickly went down. We thought it was a fluke. A few days later, it did the same thing and we took it back to the shop. They said nothing was wrong and let the car run with the radiator cap off for a while in case there was a bubble. Since then, it has has started to overheat a few more times. So the, problem is not all the time, just every so often. Several parts have already been replaced, as noted.
What we have found in common is that each time it starts to overheat, we are in stop and go traffic. It has always been hot outside too (but it is summer). When we begin to move at a regular pace, the car temp goes down. I live in a city, so it is impossible not to get in stop and go traffic on a regular basis. Not everytime we are in stop and go traffic it does this, but since the repairs, it has never overheated while moving at a regular pace.
Subaru - Outback :: 1997 - Engine Overheating In Heavy Traffic
Every once in a while in heavy traffic the engine overheats. I can't get out to check on the highway bit I suspect a an isn't on. I can drop the temp in the usual way of blasting the heat but I can also drop it precipitously by turning on the AC! It seems to stay down even if I turn the AC off - at least for a while. The radiator is new and it has plenty of fluid.

OK, 05 v8 4.6l
I am having very random overheating for last few weeks. Started randomly one day in stop n go traffic. Thought maybe struck tstat so replaced it. Same thing...replaced water pump, fan clutch, serpentine belt, coolant reservoir cap since then. During all those replacement I flushed system with garden hose. Burped system to best of my knowledge. Still overheats randomly. Seems to happen every day now at hot times (100*). I drive around all day for work so been watching it closely. Temp gun runs 190* on tstat housing at operating temp. When it was rising up in temp I pulled over and temp gun read 200 ish.... it is in fact getting hot. Any freaking clues? Oh and have pressure tested good....combustion test good...
Dodge - Neon :: Overheating When Idling Or In Stop And Go Traffic / Burps When Turned Off
1995 dodge neon... When I turn the car off, it burps, or bubbles air into the overfill tank. Car now also overheats when idling or in stop and go traffic. Temperature goes down when running heater.Not sure if it is the water pump or an issue with the radiator.
View 9 RepliesGolf V R32 :: Overheating When Driving For A Bit In Warm Weather
I've got a problem with my R and I don't know what to do. It will overheat after being driven for a bit in warm weather and then if I get stuck in traffic, boom, the temp goes to red and the warning chimes on, stop car and check coolant level. The coolant level is OK, and I can't seem to figure out what is failing. I brought it to the dealer and they couldn't find anything wrong with it and it supposedly didn't throw any faults.
I know it's not just me that sees this happening as I now have two witnesses( I thought I was going crazy at first, I could still be going crazy but the car is definitely exhibiting this issue). Which temp sensor the fans work off of? I was thinking maybe the fans weren't coming on, as soon as I get back under and the highway air is coming, it cools right back down. The problem is sometimes it happens, sometimes it does not. I don't want to continue driving thinking it's just a gauge glitch and end up overheating and ruining my car.
