Exactly what I was looking for, thank you my friend.
this Guy is a Legend any issues you have he have a video for it 👍
car was running cold, (gauge would show cold when engine is warm) radiator fans blowing like crazy, rough idle, coolant leaking from sensor clip, got a new sensor from my local store for $30 for a euro sport sedan and it took me about 10-20min to replace (given i have 0 room to work on an audi but it’s better than removing any screws hoses or clamps)
typically should be a 3 min job
had the same part on there last time and got a lifetime warranty on it. lasted me roughly 25k miles.
infinite part glitch irl
thanks for the help
Mate thank you you answered all my questions you are a legend
The car itself is not giving the engine light on but the little handheld scanner I just bought is showing that error code. I had some problems with some coils and plugs and not having reset the idle after I unhook the battery. I had a bunch of coolant that I just poured into the reservoir without measuring it correctly with some water I put in. That's the only coolant thing that I could see having happened except that I drove with the engine light on quite a bit and most of the coolant was gone but it didn't overheat.
My man! You are a legend. Thank you for your' to the point' info, it really helps.
i have a 2005 chevy its doing the same thing wht your saying im glad you are on here thanks
Thank you for the explanation, very helpful
Very appreciate this video I suspect I'm having a CTS problem.
Excellent video bro, you really break it down into a great detail. I replaced my thermo fan switch on my radiator for my VR6 with a low temp one and ever since that I noticed that the fan does not come on after the car is turned off after a long drive. Will this cause damage or coolant leaks?
What could it possibly be?
On my jeep grand Cherokee 2015 after some warm up temp gauge freezes on 1/4 and almost not moving anywhere even after hundreds of miles… is that okay? Thanks
Thank for your info my concern is that I replaced the cooler sensor but my spark plugs keep on getting wet and the engine idle is rough!!! What could be the problem oh not forgetting it stall's or there's no power while driving
Very helpful, thanks
Thanks men for explaining all these things,, 👍
Love the channel 💪🏼
Need some help on my Buick century. I've had 4 months and it's issues after issues. I'm no mechanic so I'm learning as I'm going. Overheating everyday. I've bleed the air out, sparks are good. MAF good, throttle clean. I have all the symptoms except for, black smoke and stalling out. Any advice
Did you check or replace the thermostat? Did you flush the old coolant? Do you have enough water in your coolant? Do you have any pin hole leaks on your rad upper lower hoses? Are the clamps not tight or over tightened? Is your overflow reservoir the type that is sealed? Is the cap good? Did you replace the radiator cap with a oem match part. Those are all necessary if you're overheating. Also make sure your radiator is clean on the outside and that the fan works etc. Also you need more water the hotter it is. Antifreeze is there to keep water from freezing but it also lowers the waters ability to carry heat. So you have to make sure your mix is not too concentrated
I HAD A COOLANT TEMP CODE, PLUS OVERHEATING, FOUND THE ELECTICAL CONNECTOR WAS BROKEN, REPLACED CONNECTOR CLEAR CODE GOOD TO GO
Why would it over heat from sensor?
@@Edgar-uw6vlthe radiator fans turn on at certain temperature.
If sensor bad not reading temperature and fans wont turn on
@@SmokerupI hope it stops my car from overheating
My car gauge shows overheating but the car is good temperature maybe it's need that sensor @@SugarrPlump
How did you determine it was a good temp ?@@randyrivera4433
I took my 2010 Camry to the Toyota dealer and they diagnosed my cooling sensor to be the issue of my temperature gauge going so high almost one line before it hits red, the temperature gauge kept going up and down and was never down to C anymore when my car was home all night before going to work!
Is there a second engine temperature sensor other than the coolant sensor that is beside the thermostat? Any ideas on where it would be located?
thank you your so clear about issues
Can a bad fan cause the housing to be a low level of coolant in housing for a 2005 gt mustang when coolant parts been replaced lik with a coolant flush or thermostat
My bmw 2003 x5 e53 3.0 stay on all the times from morning first start wont shut off unless i turn off the car , i checked the realy and fan switch both good , what could be the problem ?
Note: My A/C not blowing cold although its fully charged i dont know if its realted to the fan being stuck on high .
My coolant and oil temperature sensor are the same but I’m having a no start or like it wants to but doesn’t and I’m having codes for the oil sensor
I've tried two after markets sensors and 2mopar ones on my 2015 ram ecodiesel it keeps tripping my check engine light. No overheating or anything. Every few hundred miles. Any ideas why?
A few weeks back I had the check engine light come on; it was somewhat cold outside (-18C). I was in a bit of a hurry and had only had the engine block heater on for about an hour when I as per usual started the car, got outside to unplug the outlet and noticed something off with the sound from the engine. I got back in the car and saw the check engine light lit. Plugged in my OBD-reader and got code P011600. It turns out the computer went into some sort of fail-safe mode and turned the radiator fan to full blast in case the engine was running hot. I drove the 10 min ride to where I was going and noticed that the temp gauge increased at a normal rate. The AC worked as it should and warmed up the coupé on the ride so I figured the thermostat should be functioning all right. Cleared the error code and that was that; the car operated as normal.
A few days later the code came back and once more I cleared it. I ordered a replacement sensor but the error has not occurred again. The freeze frame showed that the sensor had reported a coolant temp of -40C which is nonsense since the ambient temperature hasn't yet gone below -20C this winter. I figure I'll wait and see, if it happens again I'll replace the sensor. I drive a 2004 Chrysler 300M and thankfully, in spite of all it's questionable design (I'm looking at you, whoever made the call on the placement of the battery!) the sensor is easily accessible by just popping the hood.
Any thoughts?
Mechanics i know little about but I struggle with my Chrysler 200 3.6 l a lot recently. Christmas day it left me stranded . Just died at a ted light . I ( a female) put it in neuteral to roll it backwards tried jumping in it to hit the brakes almost ran over myself. When it tapped the guardrail I had to get out and try to steer and push fwd up an incline . S little guy stopped to try and help but to no avail it didn't work then Paul bunion stopped and helped easily. Then an 8 he wait for a tow. So I was told battery, replaced it, wouldn't start then im told the starter replaced that . Now on my way to work the overheating happens so here I sit waiting for it to cool down so I can add coolant. I do have a new temp coolant sensor but don't know where or how, the person that put the starter in disregarded my needs for this to be replaced. . So I guess I'm out of work for the day but I'm wondering if its just the sensor. My car was blowing freezing air the entire time. I saw the Guage rising and before it got ¾ of the way up I pulled over and shut down however its been 15/20 min and uts still sreamung under the hood😢
Thank you very helpful
Great video love and respect this
Thanks man for the informative video 😊
Wonderful explanation Bro! Now I just need to find it on my 2005 Chevy Uplander. Thank you from Vancouver Island.
My car dash temp is cold to hot and Looks fine even When driving around. I'm confused as to why it would need changed the reading are always the same but I have a rich condition going on. I've changed map and air intake and air fuel ratio in the cat. I haven't changed the coolant temp. I'm not seeing why change it yet ..but I am alerted to it .. do I change it anyways or are y'all changing them cause the car looks to be overheating by the dash temp.
Excelent video.
Can this cause idle surge, like every time i give it gas the idle drop and jumps to 1500rpm and stayed for couple second and back down to idle.
Hi, I have 2012 Mercedes e350 and fan running high speed all the time, no code found, any idea please?
I have 2010 toyota corolla 2NZFE , 1.3 L engine, it has continouse long term rich -14% , mechanic checked every thing, 140 PSi dry compression for each cylinder. last he found that there is no thermostate, my question is , does running engine without thermostate result in LTFT -14%,? assuming other things working fine
On that last part “false reading” you mention if the engine is warm/hot and the needle on C now how bout when the engine is cold and the temp gauge needle is on H Same problem correct ?

I got a 2019 fusion 2.5 changed the temp sensor reset the check engine light was doing fine for last 3 weeks now it's back on but not overheating or anything Has ran fine the whole time even before I changed it out just temp sensor and check engine on light temps right in the middle on temp any suggestions thanks
Nice very informative
He forgot to mention, when your radiator coolant fan runs continuously, even when your vehicle is shut off, it could be your coolant temperature sensor.
Check out one of my latest video, "why cooling fan keeps running." I mentioned it in that video.
@@Top5AutoRepairs ok
This!
I just got this issue fixed today my Tahoe did this, the fan motor was extremely loud and stayed on after I shut down the engine. This is the second I've replaced it. I had to do this a few months ago. Do you think it's something else?
@@stepp-uppwithnecol4381Always use OEM or NTK temp sensors. No autoparts grade garbage

My 2010ford fusion sport v6 overheats ones a while during driving in city but not on a long drive...I'll notice its overheating because air compressor cuts off and it's not cooling the ac. Can u help??
Could it also cause a p2196 code ?
Now that’s a mechanic who knows the science behind the problem,he only make you change parts after he found out the real problem.😊
No Coolant temp Code at all but overheating , im draining the radiator today to check and see if it’s clogged, but any suggestions?
I've got an '03 e85 3.0i roadster, just replaced the radiator and got the coolant burped and levels to the appropriate amount a few weeks ago. Now I'm over heating with no engine codes, my radiator fan won't kick on and its idling really rough (rpms bounce between 1k and 800 constantly). I'm thinking its a bad coolant temp sensor but I'm not sure which one to change as I believe there are at least 2 in the system. When facing the vehicle: there is one sensor that looks like it connects to the thermostat (which I changed the day after I did the radiator) the second sensor I believe is on the right side of the engine just above a few coolant hoses. After thinking about the symptoms I feel its probably the first sensor in the thermostat because my radiator fan won't kick on, but then there is the idle issue :/. Just looking for some outside opinions, thanks!!!
Thanks for sharing
Helo sir I got thermometer sigh in my Hybrid Honda acord,what to do.please help
Thanks
My Mazda Cx5. The engine is overheating but not showing on the Dashboard reading, Fan Not working
I have a 2003 Lincoln Navigator. I noticed on my dashboard when I turn the key to on position. There’s a temperature light on. Would that cause the relay to the fuel pump not kick on due to the safety? Thanks
Great explanation thank you finally someone breaks it down right to the point🙏😁
My coolant temperature connector (wire)is exposed the outer plastic has melted off will this cause my car to go on limp mode I cannot accelerate past 20mph
HI I RAN AN OBD2 SCANNER AND ITS SAYING EVERYTHINGS OKAE N THEN AFTDR THE SCANS DONE IT SHOWS ON THE SCREEN THAT MY EVAP SYSTEM FAILED.... WAT DOE S THAT MEAN ? N THEN I HAVE A LOUD HUMMING NOISE ON THE BELT SIDE OF MY 2018 SENTRA WATS THAT MEAN?
I got a 2019 c43 Mercedes, today I turned it on at 6 am cold start, and it started a little rough, then I checked my temp and it was showing it already being warmed up? Not cold or overheated just warmed up… then my radiator fan turned itself on and got to full speed. Then a check engine light ? Could it be my temp sensor ?
It's a good idea to replace it if you think so, because it's not too expensive and easy to swap, compared to other sensors because where it's located.
When it’s super hot outside, all the warning signs come on at the same time(NOT THE ENGINE LIGHT) when I start the car. I have to turn on the AC and let my car cool down for 5 minutes, afterwards I turn it off, then restart ignition, then all the warning signs are gone. Could it be a sensor thing. I drive a 22 sonata.
i have this problem right now with my 80s toyota. i think it's the sensor because i just replaced my radiator with a bigger one, along with the coolant of course. the problem is that she's okay on idle, but when i drive normally (2-3000 rpm) the dash says she heats up quick. than when i slow down or brake it instantlygoes back to normal, but the hoses and radiator feel like hand warmers, or a little too hot to touch.
Thanks bro.
Did he have contact with transmission
Because my mécanique change the engine cooler yesterday now i have problem with overheating with transmission work with one gear the first one
hi..my car overheat some time..one off 10 times of driving i smelled engine oil burning and then when i slow down and close ac its normal back..tomorrow i check the engine oil lower a bit..what cause this?
My gauge inside shows temp lower then 1/2 mark. When finished driving car the front of car and hood extremely hot. Also losing coolant had radiator replaced tech said bad was 3 years old and still losing coolant. about 1/2 cup a month. Can smell coolant, The radiator fan runs when AC on never runs whe AC is off. I think the radiator super hot when car turned off and may leak coolant out of cap. Since fan never turns on without ac could sensor be bad? I don't think blown gasket, I thought maybe bad heater core. Had pressure checked was okay. Nothing in oil and no white smoke.
is my 96 chevy silverado ok to drive without cooling temp sensor until i can fix it? I see one of the wires is messed up at connector
You have two senders one for the gage and one for the computer.
Gage is probably not a big deal
Can someone tell me, my temperature gauge needle goes up fast as soon as I start the car, but it stays in the middle. I thought it was suppose to rise slowly. Any tips please
Does it affect the ac ?
Dodge dart 2016 when gets to running temp coolant light comes on and gauge drops to cold while running. And ac/heater stops working. Any reason why. Plenty of fluids
All other gauges work
2005 police crown vic ---- BRO I NEED HELP! been having overheating issues & replaced everything in the system. NOT overheating anymore but the radiator fan goes to high after only 5 mins of running. stays on high fan until shut off. replaced the radiator, water pump, CT sensor, HT sensor, thermostat (160), fresh coolant after 3 flushes. used a laser temp tool & highest reading on cyl or anywhere, is only 160 degrees. fan will be on HIGH with that LOW temp. CANT FIGURE IT OUT & NEED TO SELL!. NO ENGINE CODES.
It's probably Pressure Sensor in the AC, it can cause the fan to keep running full blast
I just ordered a temperature gauge sensor because these are the same exact problems im going through right now.
Did it fix your issue ??
I got this problem on a suv envoy and it was the ecu that was bad i change the coolant sensor amd keep sending the code
What could be the cause of my temp gauge to go down to cold when I have the aircon on and even if I turn the AC off again it still stays reading cold.
Thermostat, stuck open
@@iroc-z6668 Yes you where close, there was none in there.
Okay but what if I’ve replaced everything in the car that has to do with cooling and this happens but it my car gets hot after I drive for like 5mins and then keeps getting hotter I already had to replace the radiator,thermostat the fans work I’ve replaced hoses and everything besides my temp sense and I don’t think it’s my head gasket so
Me too
2005 PT Cruiser was overheating fan was not coming on replace fan and engine coolant sensor now fan comes on continuous does not overheat what temperature gauge does not register if I turn it off and back on it registers for 5 seconds what can I do please help
my radiator stays on while i start the motor when i turn of the motor its stops i have a golf 5 1.4 gasoline engine i dont know whats the isue
My coolant it's very hot. When i touch the hose. What's that mean the sensor it worked properly or not.
I have a chrysler town and country and when im at idle my car goes up one line but then the fans come on and it cools down, is that the fan switch gone bad, i havent gotten a code for anything so idk what it could be
Sounds like Thermostat, they get old and open up slower
@aaronajbird07 ive already replaced it and thats not the problem, i think it might be the coolant temperature sensor
Mine first Everytime I turn my chevy cruze Lt 2014 It say engine reduce power and then traccion On after that start shaking the engine and Went I try acceleration It goes slow I press the gas pedal all the way and it drive slow and then it show in the dash AC Due too a high Engine temperature
I have a 2015 F150 I have no leaking coolant but yet the truck runs hard after 10 minutes of driving .

I have peugeot 407 2.0hdi Fan starts after 5km drive..cold engine but fan spin and dont stop.. and temperture shows 90'c. What can it bee.. is it that sensor or... ??
I have a bad thermostat code, replaced it. But check engine light came back after 2 weeks. Cleared the code. 2 weeks later, it came back. Could it be a bad temp sensor? Both fans comes on when the AC is on (this is the only time my cooling fan will come on, otherwise it does not come on when temp is at normal range). Temp gauge is good, not overheating. Coolant was drained, bled and topped off.
Check connections. Might need to replace connector
@BruceWayne-sz3th honda pilot. But i got out fixed. Replaced both my ects
How can I send u a video for my car? My car won't start so there's no way it's over heating. My radiator fan assembly was recently changed and it still shows service engine, engine overheating stop safely and asc service required while car is off and I just turn the key to acc or on without actually starting the car. Idk if im making sense but pls help. Also I couldn't scan the car for codes because the scanner is not communicating with my car 😢
So it won’t start or it’s over heating??
Usually you have to turn the car on in order for your diagnostic tool aka code reader to connect with your car which in turn will scan the ecu and come back with not only codes but freeze frame data.
its your sensors
Hi sir.I have problem while engine cold everything ok when engine hot fan work and non stop until i stop the engine.Radiator,fan,coolant,coolant cap changed with new one
Mine also got same problem. Air cond no function well when all fan running during engine hot. Stop engine and re-start everything back to normal.
I have a 95 gmc k1500 that will start but will die. It will idle and then it will die. It will putter like it’s not getting enough gas or air. I changed the fuel pump and fuel filter. Thought it might be the maf sensor or the ect sensor. If you know what to do with this situation plz let me know.
Oh and no check engine light
The coolant temperature sensor, does it affect the temperature of the heater inside the car?
HELL YEA
Ive replaced it 3 times on my 2015 tahoe 3 times and it fixes everything and then a few days later it starts acting up again. Any guesses what would cause the senson to fail multiple times??
dirty coolant. old coolant is extremely corrosive.
Does this also cause sluggish acceleration and misfiring?
Yes

My fan stay on as I turn on my car an it don’t stop till I turn off my car what causing that problem?
Mine over heats when the ac is on but I’m only getting the p0125 code for a 04 impala

Will it cause you car not to start?
I have a 1996 Chevy Silverado K1500 Z71 w/5.7 350 Vortec , i just inherited it as one could say and its been a pain in the ass. To start with it had trouble starting at first, usually upon first start up it would catch mid start then almost die with 60% of the time it catching and starting but 40% of the time it sputtering off. The 2nd problem was the distributor/cam sensor adjustment, even though it is an EFI spider injection it still uses a distributor to fire (note its not actually a distributor but i don't know what its actually called and it isn't coil packs). After all that it still has issues but the man code it always throws is PO160. Another thing to not about that is it doesn't have CAT's on it, i live in Texas and the EPA can kiss my ass, but anyways atp A: either sell the pos while im still not fucked or B: install an intake manifold and carb as well as HEI distributor and some how mock up the old 4L60E.
Mines showing -40 but gauge shows normal temp?
