Toyota - Camry :: 2001 - Overheating / Fans Seem To Come On Only If Turn On AC
Oct 29, 2013
I have a 2001 toyota camry ce in Miami, fl which is overheating. the fans seem to come on only if i turn on the a/c. however the temperature still rises and gauge needle hits red. if on idle the fans never come on. observed fluid inside radiator with cap off and it does not run through while on idle with a/c off, it just gets hot. changed thermostat and added new 50-50 antifreeze, still same. I'm suspecting a switch but why is fluid never running even when hot? I even drive it with hood open (unlatched) to let a bit more air in and still overheats, even with a/c on and fans running (again, they only turn on with a/c on), it overheats.

I know the alternator needs replacing but why are the fan relays not working correctly. Also, the top radiator hose is really hot? I replaced the thermostat as well as the coolant reservoir? I also replaced a couple of the fan relays from my older wrecked Camry. Would the noisy alt that is going out have something to do w/the fans and fan relays not working properly?

My Camry seems to be overheating. When I'm driving the gauge maintains and reads 6/10, when the engine is idling, it goes upto 8/10, radiator fans kick in and then temperature goes down to 6/10 and keeps cycling over a period of 5 mins.
It's got 100K miles, water pump has not been replaced yet.
I checked the hose temperature; top hose 210 F, bottom hose 192, fans kick in when top hose is around 215 F.
I checked the engine temperature where the sender is installed and it was reading 205 F. Coolant level is OK. I burped the system. Previous owner told me, he had thermostat replaced by dealer.

My head lights in my Solara turn on automatically when I start the car and off when I stop the car. But now when I turn off the car the lights stay on which kills my battery unless I disconect the battery. Which is making me fail the computer part of my emission test. What is keeping my head lights from turning off?

I have a 2004 Camry that the cooling fans won't turn on at all. I checked one of the cooling fans by running direct power and it worked. I then checked all the fuses relating to fans and A/C. Then checked relays by using the horn relay in Fan 1 and Fan 3, which are both 4 pin. I bought a new relay for Fan 2 as it was a 5 pin and still no change. The fans don't come on at any stage, turning on A/C or letting the car idle to the point of the water boiling from overflow. I'm thinking it's not the sensors as the fans should turn on when the A/C is turned on.

I have a 1992 Toyota Camry. It had been burning gas, losing powere, white smoke smoking excessively through the tailpipe, and idling extremely rough, sometimes to the point of dying. It ran ok at highway speeds, but terrible everywhere else. We figured that it was getting moisture into the engine. We essentially did an upper engine overhaul, replacing gaskets and parts as necessary. It ran fine after this, and then three weeks later, started having the same symptoms. I found gas in the oil, changed oil, which turned it to run smoother, but still smoked and died at idle. I found out the clutch fan barely blows. I can't afford to get an actual mechanic involved, but I don't know where to look next.

My 89 Corolla started overheating when I turn on the AC. If I don't use the AC, the temp. is fine. 2-3 min. after turning on AC, temp. gauge rises and I must turn off AC. My husband, a devout CT listener has some mechanical skills & ck'd it out. He replaced the fan relay, but that didn't fix it. History: the 1st time it happened, the AC was on and blowing cool air, suddenly, the air wasn't cool and I noticed the temp. rising and turned off the AC. I stopped and checked the radiator fluid and it was low, so filled the overflow with coolant. Drove home (30 min.) and it was fine.
A week later, same thing - I'm on the freeway, air is blowing cool, then not and heats up. Ck'd radiator - fluid level is fine. Problem was somewhat intermittent as it wasn't happening 'all the time'. Yesterday, same thing again on the way to see the dentist 40 min. out in mid-afternoon sweltering heat. Had to drive there and back with no AC - quite miserable. Replaced the thermostat not too long ago and the radiator also had to be replaced year before last. I have health issues and really can't handle the heat and fumes and must have AC in this climate. We can't afford to take it to a mechanic. If this car goes, them I'm car-less. It's a great car and keeps on going - 240,000+ miles.

I've figured out why my car has been overheating lately, the fans aren't running at all! How do I get the front end off and check things out, is there a fuse diagram for the B6...

A couple days ago I saw that my Toyota Camry was overheating, the gauge was going about 3/4s of the way and then returning to normal. I had then replaced the T-stat but noticed the fans were not running, so I replaced the relay as it tested bad. The fans then started to work when the A/C was turned on, but I noticed the car was still going 3/4s of the way then returning to normal.
So, I took it to a mechanic and looked for his opinion on it, he tested it and said that everything is working fine and when the engine gets hot enough the fans kick on, bit the gauge still hits 3/4s hot and then returns to normal. My mechanic said that he has seen this before in other car models and that everything is working as intended. I was just wondering if this is a common occurrence with some cars? Or should I look for other possible problems? I've never personally owned a car that looked like it was overheating then quickly corrected itself.

As the title says, car is overheating. Car gets to 190F within a couple miles drive. Temperature fluctuates between 190F and 225F.
Water pump was replaced ~2 months ago. Was not overheating prior. Temp reached 190F and stayed. Currently has the "black top" coolant temp sensor.
I noticed the coolant fans are not running after I turn the ignition off. This time of year they would usually be running after turning the engine off. If car is overheated and with AC off the fans do not run while engine is running.
I used the guide below to try diagnosing the cause: [URL] ....
Remember both fans should come on in slow speed any time the key is on and the AC is on - if the temperature is above about 32 F (0 C). Both fans run with key on and AC on
S180 (fuse 8, 30 amps, green plastic, above battery) must be good for slow speed operation.
Fuse and holder look good: no melting, no discoloration.
S164 (fuse 3, 40 amps, metal strip, above battery) must be good for fast speed operation.
fuse looks good: unbroken.
To ensure the AC circuits and the Fan Control Module has power check:
Fuse 5 on the cabin fuse panel.
Fuse 16 on the cabin fuse panel. When this fuse is blown the radiator fans will often run unexpectedly.
Fuse 25 on the cabin fuse panel.
All three fuses look good: unbroken
For the first test of the slow speed fans from the radiator thermoswitch have the key off.....Both fans should run in slow speed.
Passed test: both fans run slow
The second test is for the fast speed fans, key on, AC off.... Both fans should run in fast speed.
Passed test: both fans run fast
If the fans run in the tests above, then you should be good to go. No further tests are needed.
If you have been seeing high coolant temperatures and the fans have not been running, then you may need a new thermoswitch.

My 1999 Accord V6 with 180k miles has started overheating. The fans will not run unless the A/C is on. I replaced the coolant temp switch A, because the fan came on when I jumpered the pins of the fan connector. The fan will not come on, even when the temp gauge goes all the way to the top. Jumper the pins or turn on the climate control, the fans kick on, and the temp drops. Tested the old temp switch in boiling water and it tested fine. Tried spreading the pins on the temp sensor in case the connection was just bad and that did nothing.
Otherwise, the system seems to work fine. Top coolant hose gets hot first, then bottom gets hot after 10 minutes. The heat works, and I didn't see any signs of exterior leaks. What else might keep the cooling fans from coming on?

I have a Toyota Avalon 2001. When the dashboard multi-display reports a temperature >84oF, the clock and/or trip odometers reset, and other readings go blank.When the car cools sufficiently, all functions resume (though clock time has to be reset).
The problem has been narrowed to the multi-display module or its connectors.
Is there a way to keep the car interior cool when it sits unused in a parking lot?
I currently leave the windows open ~2in behind rain covers, installed last year, that prevent unpredictable thunderstorms from introducing mold through the partially opened windows.I currently use a reflector in the window. Both of these observably drop the cabin temperature ~20oF ,yet it is not enough.I have tried a fan, powered by the car's battery, but extrapolation from measurements indicates that before any fan moves enough air to have significant effect, it will leave the battery too drained to start the car.A solar panel powered fan generates more heat than it removes.
Is there a way to remove the expose (and reseat) the multi display connectors, by just removing the padding above the dashboard?
I have the service manual, but have not yet found how to get access to the multi display, without removing the seats, and all cowlings from the center console forward.

2006 Toyota Camry 4 Cyl Manual Transmission. I'm getting a PO017 code - Engine Coolant Temperature (ECT) Circuit Low Input.
The dashboard temp gauge reaches a red H at low speeds. After about 15 minutes of driving, the car overheats and shuts down when the car slows down. I wasn't at home and didn't have coolant, so I put water in the coolant reservoir. 15 minutes later at home, the car overheated and shut down. The water in the reservoir was boiling and steaming.
When the car is idle, the radiator fan turns on immediately. I noticed the passenger side fan doesn't run. Could the one fan be the problem?
I was also really low on oil and added oil. There's oil on the engine block too. I might have multiple problems at the same time. See pics. [URL] .....

So my friend, ignoring my advice that this generation seems to be riddled with electrical problems, decided to purchase a seemingly nice 99 Jetta, with a junkyard AEG swapped in(AEG is written on the intake and block like a JY would do). Sun roof doesn't slide back, gets jammed, evidence shows water has built up previously and run down the A-Pillar to the fuse box.
I just got the fans unplugged and verified that the fans with power applied, both have their low/high speeds. The fuses on top of the battery are in-tact, no visible melting, looks like the thing is in ok shape(haven't taken them off to inspect the contacts yet).

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?

My car just started over heating and I checked the fans and they are not running. I'm new to the VW family and although I love the way this car drives I've been baptized with quite a few problems.

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.

My Subaru just had the thermostat replaced, and it seemed to work until the wife took it she said it over heats when not driving the fans are working, it's over flowing out the reserve tank the fluid looked good when changed the thermostat so I don't think it's the head gasket my next guess would be either the water pump... After I last changed the thermostat and test drove it I felt the upper radiator hose it was hot but the bottom one was cool/warm.

Long story short on a trip (about a 1 hr. drive) got about a block away from destination and gauge showed it was over heating. Stopped the car started up after five min. just fine. Got home replaced the thermostat and cap (old cap was junk). New cap was junk aftermarket so yesterday I took the same car on a half hour drive to get a Mopar cap ran just fine up again until a block away, pulled off the road turned it off let it set a few min. then didn't even show it was over heating. Let the pressure off and replaced the cap and added in a bit more coolant ran fine all the way back (even pushed speed in a few spots).
The above is just what seems to be the mechanical side of the issue. After noticing the gauge was going a bit above the normal spot I noticed my cooling fans are not coming on. Checked fuse and tested relays out to be fine. First thought is to check voltage to the fans but also tempted to check coolant temp sensor with bench test. Will be going over to my dads to do voltage testing later today.

So I noticed my temp gauge was starting to rise when I was on the freeway. I figured my fans were out but I just opened my hood and both fans were spinning. When I turned the car off both fans turned off but the temp gauge was almost into the red.
In the morning I turned on my AC and only the passenger side fan was working.
So I am not really sure what my next diagnostic step should be. The engine was not radiating any heat so I am not sure that it is even actually running that hot. Could it possibly be the temperature gauge? If I got a vagcom would I be able to check the actual temperature from there?
I am also concerned on how to find out if the fans are running at both speeds at the appropriate times.
Not sure if this is related but my cruise control stopped working a few weeks ago also.

My '01 Grand Cherokee Limited is overheating. I have changed the thermostat and ran a leak test. I am not having a leak. The temp drops when I turn on the A/C or heater. I went back to the shop that changed the thermostat and leak test. They said it was the fan control and I have to go to the dealer to reflash the program for the fan control. I made the mistake of asking the dealer to reflash, instead of having them check on the overheating problem. I'm planning on going back to the dealer to have them diagnose the issue.
