- WHY RADIATOR FAN STAYS ON ALL THE TIME
If your radiator fan stays on all the time when the car is started or with the ignition being on we will explain what is causing that. Radiator fan should not stay on all the time. The radiator fan is supposed to be activated at certain coolant temperature or the radiator might be on if you have the AC turned on. We will demonstrate what could cause that and show you how a bad temperature sensor made our radiator fan stay on all the time.

It happening to me now
I know Im asking randomly but does someone know a tool to log back into an Instagram account?
I stupidly lost my account password. I love any help you can offer me!
@Franco Brecken Instablaster ;)
@Rohan Wallace i really appreciate your reply. I found the site on google and im trying it out now.
I see it takes quite some time so I will reply here later with my results.
@Rohan Wallace it worked and I actually got access to my account again. I'm so happy!
Thanks so much you really help me out :D
When cars used to have basic controls it was a far better world, too many fancy sensors and electronic shit these days.
More you have more you pay😂😂😂.
False, reliability has grown leaps and bounds over the years in most cases, you saying carburetor is better than efi?
Vauxhall is the worst for sensor lights coming on..2 of mine came on 3 days after buying my Corsa and they said no problems with the car ( they was right ) and it was just the sensors need replacing but didn't bother replacing 45,000 miles still on..I just check oil and radiator weekly
Good tips and you go straight to the point. Others talk for up to 14 minutes before they go to the issue. Time is gold.
Indeed to the point. Great video.
Thank you for this video!! I was so stressed today when my fan would not turn off.. I checked my relays and that did the trick!! I appreciate people taking their time to share their knowledge with the rest of us dummies! 😊
Did your check engine light come on or no?
What did you do checking your relays t hat fixed it?
Thanks! You saved me a trip to the dealer. Mine was a bad high-speed fan relay. 1 minute fix once I got the part.
I've been chasing this problem in my ram 1500 for almost a month... Turns out the relay was loose! Thank you so much. I was about to replace the whole fan...
This is perfect!
Two wild and crazy guys
I don't have an engine light on just a a loud fan running wrangler 2017
I’ll try this when I get home thanks for sharing
Great to the point video thanks 😊
Nice E46 m8 and choice of work wear 👌 greetings from the UK 🇬🇧
Really love you guys and the effort and your knowledge you share with us you guys are a pleasure to watch
Awesome, thank you SO MUCH!
Thank you!
thanks for your efforts
impala 2012
no blown fuse all relays good
fans not work
good ect
only with scan tool using active test
please tell me about the problem
my fan is running don't stop my car is Hyundai atos 1.1 l put new water pump ,take out thermostat but still
Might be bad fan control module
Omg thank you for this
There are good problems, bad problems and fatal problems in a combustion car. When a radiator fan is not turning On know that you are having a fatal problem but when the a radiator fan is alway On then that's a good problem. A bad problem is when you had installed new parts and checked everything but the problem persist.
good video guys
Hi
2009 BMW 328 got p0598 (thermostat circut low) mpg went down from 23 to 19 now. When I drive little fan comes on and never stops. If you have experienced such code from your experience what it could be? One machenic told me it is thermostats.
I replaced the radiator fans in 2018 dodge ram promaster because it keep coming on and off withing seconds they said it was the module on it so replaced the whole fan new modules it still keeps doing it it can be cold outside and it comes on and off on and off withing seconds like a cycle ? Dunno why
In the case of a faulty temp sensor, would the temp be reported accurately in the driver’s console? Thanks for the video!
Often a separate sensor
I have skoda Octavia 2 2006 tdi model. As soon as I switch ignition On, both fans start in 10 seconds and remain ON until ignition is put off.changed both temperature sensors but still doing same. Please guide
Hi my relay went so I have just been removing the fuse each time I get out of the car to avoid draining the battery (I don't use the car much and I'm a bit skint). Now although the fuse is fine and I've also bridged the circuit to test, the fan isn't running at all. Has this likely burnt the fan motor out?
Can you tell me what the problem is on P0096 code Nissan xtrail 1.6d T32 2016. The maf sensor has been changed but after while again engine sign come up and taking readings of OBD2 intake air sensor shows 102C. Is it of a MAF sensor that figure came?
I still got to take my ass to the mechanic but I appreciate knowing a little now what is it about. Ty
hey is it bad if i don't stop the fan from running after I shut it off I have a chevy volt 2018
Thanks guys for guys giving guys me guys this guys information guys
My problem on my 04 Hyundai Elantra GT seems to be just the opposite... The fans are going on and off at idle, but they seem to be turning off at high speeds and my engine is overheating when the A/C is on.
Thank you for the information. My truck is not heating up to full operating temp. I've replaced the ECT sensor and thermostat with little change to the issue. This morning the temp was 34°f and the fan came on as soon as the truck started. Is there a way to check the relay?
Just had this with my car changed the 2 temperature sensors fan was still on. Then changed the resistor. Fan was still on. Bought a new thermostat comes complete with housing unit £17.89 of eBay stuck that in myself pure easy 3 bolts. Seems to have done the trick. My fans off. Warning light is off car running like a dream. You also have to top up coolant so buy 2-3 litres as you lose almost all of it when changing the thermostat. X
Thx i have replaced literslly everything radiator, fans and all sensors and still issues. Gonna be pissed to find out i just needed a thermostat
Ur welcome... A read a million forums only one person said the thermostat... Every one else said sensors, resistor, fan relay... So thought people neede to know... X
i have 2009 nissan altima 2.5l
radiator fans staying at low speed
all the time is the computer the one controling speed?
I has an ambient sensor code . Both Fans turn on instantly at high speed. I rushed and changed sensor . Didnt work. Tested old sensor ohms and it was working. Tested power to sensor and nothing. Found wires cut. I tested voltage again and there was no power kept tracing the wires. Found it cut in another place . All fixed . And now fans works as required .
vw cc.
fan stop running and i changed the temperature pressure sensor and the fan start running but it comes on and stay on when i turn the engine on and goes off when i turn the car off i don't have a engine light so i changed the relay that said lower fan and nothing changed so i guess i didn't change the right relay out i have a 2010 hyundai Tucson
Hi. I have a nissan b15 1.8lt
Fan runs at ignition on. Changed the temp sens and chk relay..wires are ok. What can keep the fans running? Fault code p0335...changed the crank sensor and cam sensor. Still getting p0335 code and fan still running
I’m not familiar with that vehicle, but possibly a fan clutch? That’s the issue I had with my trailblazer
Thanks for the video. Very informative. Could you advice. I have a 2015 ford focus 1.0. My cooling fan turns on few seconds after starting the vehicle even when the engine is cold and keeps running until i turn off the engine. Forscan does not show any DTC and i do not have the engine light on. I thought its a relay R12 and i changed it but the problem continued. I even changed the coolant temperature sensor and the problem was not solved. I changed the radiator control module and nothing changed. What do you think is the issue here?
I have the same in my audi a3 2008 1.4 tfsi also no faulty codes when i went to the mechanic today he pushed a little on the tepreture sensor while the car was off and it stoped after that i drove it for 5 min did a emergency brake and the fans came on again we tryed prasing it in again but it did not help (the car is not overheating in any way drove it 50mph for 1 heuer ) i need help im out of ideas
@@mytunes5007 Hi there. In my case I figured out that it was the radiator control module that died. I changed it and the problem was solved. Please make sure to check it, if its faulty you need to replace it with a new one, not an older one from scrap yard. You may need to check your coolant temperature sensor as well.
Just replaced coolant temp sensor and fan turns on after a ride around the block ?
Ect ok
Thermostate ok
Refrigan sensor ok
Relay IPDM has replaced
But the fan still on...was there the wiring harnes got problem or the ipdm has damage?
My fan starts running really hard and loud when I turn my 2010 taurus sel off, and it runs like that til the battery wears down. I have to jump it off all the time. It's very inconvenient. Do I need to replace the whole fan?? It's not the relay switch. That was replaced.??
Since my coolant levels are fine, is there any danger in driving with fan still constantly blowing high? FYI- it doesn’t blow when it’s cold outside but when it’s over 60 degrees or so.
Hi please advice I've got 2012 peugeot 3008 1.6 A/T vti petrol my fan allowys on while driving sense starting the engine and when I switched the engine off the fan stay for 5 on then it's off and the battery many times died please help and the car taking so much petrol, thank you
so am I just dumb? lol I just got a 2022 Dodge Charger scat pack, it started having some issues and the dealership "fixed" it but I got it back and theres a bad grinding noise I haven't figured it out yet, I'm bringing the car back to them in the morning. But another thing that threw me off is the radiator fan not being on... I thought fans were on at all times, my other vehicles are a 08 Ram 1500, 01 F150, 01 Yukon, 08 Mustang I have never ever had the hood open on any of these and not had the fans turning. My Chargers fan was not blowing when I first heard the noise and it was not blowing when I got back home after driving approx 38 miles. Its a scat so the car is LOUD I'm not going to hear a fan come on and off... but I have not seen it operational. I know I'm not a mechanic but it was weird as hell to me to not see that fan moving, I've done basic enough repairs I can do myself to many of my vehicles I have never seen their fans not spinning. Never.
I have a mercedes c class w204 2009 when I turn it on even though it is cold the engine turns on the fan and never stop .
I had the same problem with exact same car, changed compressor & still not fixed... did you figure out the issue?
I have a 2008 bmw 750 li, and my fan stays on even when I turn the car off, I been trying to find the relays or fuses but it seems that my car doesn't have it, do you have any suggestions or ideas?
that sounds like you are grounding out somewhere on the wiring to the fans
Same
My vw touran , the fan comes on immediately after turning on the ignition and sounds real bad even when the ac is off, and actually keeps the temp gauge low. Any help
This channel just reminds me why i hate my '11 dodge avenger (my 91 dodge truck, much better). That gen of car suuuuckkss. This channel is amazing though
Changed gearbox on golf plus 1.9tdi and after reassembled the cooling fans now run all the time as soon as I turn the key. Was working perfectly before. Any ideas? Runs perfectly and coolant is fine, not over heating. Done 6000 miles since but it's really annoying me,especially at a drive thru 😂
I have a sane issue with my golf. Have you fixed it?
same with my audi a4 i fixed thermostat radiator and water pump but as soon as i trun the key is running n my temp is going very slow to 90°..5 min when e turning down temp is going 80° is fck annoying me lol
Great video, but I,ll still to take to the garage
I bought a 2013 passat and once I turn the car onn the fans start spinning and really fast I feel vibration? any help
This is what happened to my car 2007 Kia Sorento after I replace the radiator! The fan went on right away waiting for the bubbles to get out of the radiator and cooling system. So the engine was actually cold yet when the radiator fan went on before the antifreeze got to operating temperature. Help please? Also I have no check engine lights. And the car is at operating temperature where it should be.
I have a VW polo 1.2 and my radiator fan turns on very soon and runs very loud and then the dash lights start flickering. I tried to diagnose but it doesn't say anything about temp sensor instead it tells me to check car generator.
I have a 2014 Chevy Silverado 1500 and my engine stays on high speed and the a/c don’t work as well and also the temperature gauge does not move.
I have the 2014 Silverado also, doing the same as yours. Even when I turn truck off, it is still running. I had to turn key, crank, turn off, to make it finally stop. What did yours end up being? $$$
Lorenz Rosales...
Same problem exactly if someone found a solution plz share it.
Did any of you guys get it sorted out?
hi how do i make it so the fan is always on? my engine is a hot toyota and i want it always on. please informaion if you know. nice videos
Bypass the relay with a wire
I have a 2016 Silverado Ltz and the radiator fan stays on the entire time the truck is running. Also the ac don’t get cold until 10-30 minutes. Then is blows super cold all day. I changed the coolant temp sensor and disconnected the battery for 10 minutes and it still doing the same thing. I’m not getting any codes and my gauge on the inside is reading correctly. Any ideas?
Having same problem on a 04 Acura rl
I have a 2015 X1 2.0t cooling fan comes on with little heat coming thru the vents and I lose turbo power. Have replaced water pump, rad, thermostat housing, thermostat twice, ambient temp sensor( because it was showing -40) nothing seems to work. This started after replacing the rad and water pump. It has been to two shops one of which is running ISTA d and neither can find the fault . HELP
My chrysler 300c has this problem from a cold start - fan running and no temp gauge reading. Codes for temp sensor and t stat which I have replaced and still no luck. When I restart the car after a couple of minutes fans cycle normally and temp gauge starts working. Been to mechanics and auto electricians and no one can fix her. Any ideas here people cheers
My Logan car radiator fan is running fine in normal climate according to the temperature, but while sunny climate it keeps running..No body could diagnose this issue. I changed thermostat, ac pressure switch but nothing worked...PLEASE HELP
Hi
Always there is daiode in the thermal resistor of the radiator fan
Do you know how much or the size of
this daiode?
No show me
My Skoda Octavia 2007 Radiator Fan Constantly Running despite ice cold engine. :(
Changed radiator fan relay. Still Same Problem. :( :(
Change thermostat
1997 camry 4cyl.
Temp sensor works fine because temperature goes from cold to warm completely normally.
But my fans are always on.
Thermostat is new.
Idk
Sensor for the guage and the fan are separate
@@heyyou5189 found that out 2 weeks ago. Fixed the issue.
Thanks!
@@davecrupel2817 what did your issue end up being?
@@cam-3461 Short answer: a rather irritatingly hidden addition to the coolant system that nobody explained to me untill i found this video.
Long answer:
Turns out there is a 2nd coolant temperature sensor on that car that i.didn't know existed untill recently.
You have the one right at the coolant return line, which is easy enough to access, and sends info to your temp gauge.
The other sensor, as was unbeknownst to me, is at the bottom of the radiator. Right at the start of the coolant sending line. This sensor controls when your cooling fans turn on or off.
It stopped working.
And if the car detects no sensor readings from.there, it will keep the cooling fans on for redundancy. Smart design choice. I just wish i had found it sooner.
@@davecrupel2817 So it’s the radiator fan switch that isn’t working?
Sort sockets when replaced the new one
Mine stays on even with the key taken out .... I have to pull the battery terminal. It just happened last night after I went thru a car wash - - maybe water caused it. My car is a 2006 C-230. The fan actually behaves properly when the engine is running. Any ideas ?
funguy4utube did you figure it out? Mines doing the same thing i have a 07
@@paugtrrz9530 Did your fuse box get wet ? With mine the next morning I figured I needed to dry it out ( per the problem I described - I went thru the car wash with the fuse box cover off by mistake ) so the next morning I simply drove the car for 15 minutes with the cover still off and the heat from the fan died it all out and it went back to normal behavior for the fan.
low coolant.
And if it not turns on on a e46, but it turns on whit laptop when i click activate fan...
couldn't the problem also be a bound fan clutch?
I FOLLOWED THE TIP THAT MY 2021 BLAZER THE FAN STAY ON HI EVEN THE ENGINE IS OFF. REPLACE A 3 YRS OLD BATTERY AND NOW THE FAN IS OFF AND THE TEMP STAYING NORMAL HOT RANGE. HOPE IT'S BEEN A WEEK NOW AND STILL WORKS.
What if the fan doesnt turn on when heating but it turns on when u unplug the temperature sensor??
Need help.
Relay
Or bad wiring
I have a BMW with this issue. Can I drive it 20 miles to my BMW repair/dealer? Or should I have it towed? Thanks
You can drive it.
Hell, you can live with it.
The cooling fans being on isnt going to harm anything at all.
On the other hand, if they stay off, and never turn on, _THEN_ driving it 20 miles is not a good idea unless 18 of those miles are highway.
Good evening, I have a 2012 chevrolet aveo and the radiaror fan works and stops all the time. I changed the thermostat I changed the water pump I changed the water cooler. I noticed that after the thermostat the collar is always cold while the rest is hot. An engineer who went to the car told me that I had to put in the original thermostat and change the pipe from the water bucket to the end of a plastic valve. because there is no ventilation .. the temperature light has not come on. Can you help me if I change the thermostat to genuine will solve the problem
i got an audi a4 b6 1.9 tdi..i changed all water pump thermostat i cleaned radiator but my temp is going up slowly af and my fan stays on as soon as i turn the key..im not done yet w my car but i think maybe some temp or fan sensors or thermostat is always open
@@illyrianeagle9571 Good evening, my friend. For me, the problem was ultimately in the air condition valve, it was stuck open when I changed it, the problem was solved immediately
I’ve the same issue in my 2006 Honda Civic.
Engine light on, radiator fan working all the time. And the Gas is going crazy working like a V8 engine. I did change the coolant temperature sensor but still same. Gotta check the relays now.
If anyone knows what’s the problem is. Please let me know.
Thank you
fix it ?
have you changed it?
blowing the relay when we replaced the new one
Drinking game:
Take a shot of Vodka everytime he says "guys" 🤭
It caused my car to run sluggish while driving. 2002 v6 mustang. It didn't even rev when I stepped on the gas..it was just sluggish
That’s how my Chevy Cruze 2012 is now
@@sunshine32375was it the temp sensor? I’m having this problem now on my 11 cruze
My car has all that good but I haven't looked at the fan resistor
My fan in my Renault Megan keeps staying on 4 garage,s it's been looked at £800 from my pocket I have had enough , no engine lights on or any other light on in dash board , I will take it back to the garage show him this video , I have really had enough of garages,
I brought my car to the mechanic to check out the AC but he messed around with the relays and now the radiator fan will not turn off( when car is on ). My engine light isn’t on either please let me know what can be the problem. The mechanic didn’t know what’s wrong either
Never go back to that "mechanic."
Hi. Did you figure out what it was have the same problem on my 2010 vw cc the fan keep running and the lights are not on top
Video is for Mopar, not my vehicle!!! Probable cause could be similar
Replaced the new relay and it blown up short secket
I have a slightly different problem. The radiator fan does the same thing but only when you turn the aircon on. Then it stays blowing full, I have to turn the car off to reset it. It's not the relays. No check begin light.
Thats normally, your aircon needs airflow through the condenser or it won't work
@@blakepenney3951 It's not normal to stay on high. It's meant to switch down.
@@almonies Every car is different. Some need to have that high level fan in order to maintain a consistent airflow. Other cars can fluctuate between fan speeds
@@ricardoperez8879 Thanks but there was an excess of gass in one side if the aircon line. It was causing the fan to speed up.
I know someone s car and the fan is on all the time and louder than the car engine with waves of heat coming from under the car
4th video suggestion when I search the exact title.
I didn't get what you said first you didn't solve the problem 🤣🤣🤣
Can I call you

hi, I’m just wondering if anyone here has experienced the fan turning on randomly while the cars parked. This can go on for several hours and it stops when I lock/unlock the car door. Mine has happened several times now and as a result the battery drains and I get the battery low warning when I start the car. Have checked the auto climate control settings and nothing is programmed in, it’s a feature I never use.
My radiator fan goes on everytime i swith on the AC even if it the first thing i do when i get into my vehicle, what could be the cause?
that is normal, fan is supposed to turn on with AC on.
everytime? whether cold or hot, morning or evening and even if its the first thing in the morning?
@@jnr.3masuku629 yes
In my car I drive it for 30+ in the morning and the needle is still reading that it’s running cold and the fan stays on even with no A/C or heat
My shit doing the same thing and if I can fix the problem I would make so much money from driving but I’m stuck driving a gas guzzler
I changed my radiator fan on my 96 bmw 318ti and it works but now my car turns on and then Boggs down and turns off. But it worked fine before. Has anybody ever had the same problem? I stumped!
Funny it’s a dodge 😂 mines is doing the same crap 💩
Guys, hey guys. Lets get to the point, guys. Ok guys
On my e46 it stays on after I start the car, no matter if it's a cold start...
dump the revving engine on your intro!!
What car ? This I can’t use on my car.
Your car doesn't have a radiator, coolant sensor, wiring harness or fuse/relays?
Weird.
can barely understand the dude.

Thank you !
