Here's something I can only refer to as a cascade failure. Purchased a new beetle cheap. Changed the heater control because the heater wasn't blowing, timing belt, water pump, and tensioner because I wasn't sure when it had been done last or ever done, since the odometer reads 130,000. Before I changed these, I noticed no heat from heater. Replaced the thermostat. It was stuck open. After that I found radiator fans weren't working. After testing found the thermo switch wasn't working. After all of that, suddenly got a code for the ect. Replaced that, now I have heat. I only paid 800 for the beetle, and I plan on driving the heck out of this car. I call it my beater bug. It runs really great! It's so fun to drive, and it's bigger on the inside! I guess that's why it was only 800 bucks! I've done much more to this car, but the cooling system had been badly neglected. Not really that expensive to fix. Oh. And one more thing. I tried to replace the reservoir on it but the after market bottle that I got from autozone had a problem. The pins in the sensor were too short and the connector wouldn't make contact so it kept giving a red flashing light on the dash. I ended up putting the old one back on and took that after market piece of junk back to autozone. That's my story. 5 speed standard. I love this bug!
Can I join your nightmare , It was recommended for me to change thermostat and W/p + belt , until local mechanic put things right for me.
I spent £180 for previous work , the offending part was £5.95😂
Volkswagens, everyone calls them trash yet you replace 4 parts, all very diy, and they run for another 20 years 🤷♀️🤣🤣 my golf is 20, I bought her super cheap, she wasn't loved at all, so now I'm replacing her sad parts and turning her into the car she can be. Though the entire thing, she's run. I'll never own another car. Vdub for life.
What year is your beetle?
@@powdere4donuts
It was a 2000. I sold it to downsize.
I basically have the Jetta that is your beetle. 5 speed w/ the 2.0 CBPA. Dude, you take care of it, fantastic and reliable setup that's relatively cheap to maintain. Only thing I insist on, have the dealer do your oil changes and flush the coolant every 2 or 3 years. Also heads up, don't be surprised if you find oil in your coolant soon. The oil coolers fail pretty often, on my third in 200k miles. Keeping really good coolant and checking your fluids at least once a week will save you from bigger problems down the line with this issue as you can get coolant in your engine when this cooler fails, vent your reservoir after running the engine anytime you turn your car off to keep it from pushing into the oil. Otherwise under pressure it'll push the other way since oil is under a much higher PSI. I had thus issue for months and surprising I never had an issue. The dealer is happy to preemptively tell you about certain maintenance though so it's worth the expensive oil change. Always Castrol 5~40 Edge Syn too!
My 2004 VW Golf started taking multiple tries to get it to start when the engine was cold from sitting a few hours. I replaced the Coolant Temperature sensor and it cured the problem immediately.
Did you have a code?
Always helpful . Years after this post . I’m a B5 guy and still have the 99 passat i took the kids to kindergarten in . Son has just helped me swap it to manual . . Never replaced the temp sensor and it’s black . Go figure . You covered all the likeliest potential issues Humble guy . Thks again
Hi mate I have a b5 Audi A4 (same chassis) with a 2.8 V6 I have a hot engine stall and not start issue I will be changing the temp sensor soon hoping it will fix. Did you have the same problem?
When you buy a VW they should include an extra coolant sensor in the glove box because you're going to replace it eventually.
Garth Goldberg LOL I have replaced enough of them to kind of agree. But I think price wise, they are about $40
When you buy a VW they should give you a box with extra parts for the whole damn car as there are no parts that will not need replacing soon, it seems as if they go out of their way to make things as unreliable as possible.
Philip Koen. I have a Volkswagen Jetta 2011 with 110,000 miles and never have this sensor bad , is a very reliable car so far

The only difference between a Volkswagen and a bucket of shit is the bucket..
Hey Charles... love your clips very informative, and doesn't treat us like dummies. Having issues with a New Beetle - just fitted new MAF - made no difference, but your explanation of the temp sensor makes loads of sense ( Really bad cold start, huge dead spot once running) . It's a green one, but cheap enough to replace. And easier than the next step which has to be the fuel filter & pump.
Dude! I don't know what to do without you? You have been my go-to guy since buying my 99 Jetta MK4. You are very informative and I especially appreciate your dissecting parts for better understanding. Wish you lived closer LOL You'd be my new bestie ❤😉 Please don't go anywhere!
Thanks for this video HM! I had the starting problem with my 2000 Eurovan VR6. Replacing the GREEN Coolant Temp Sensor fixed my starting problem. I didn't know there's 4 Coolant Temp Sensors in my engine. Crazy!
The Eurovan is a whole different beast!
@@HumbleMechanic Your video helped convinced me it was the green CTS. Had to share your video to my mechanic to also convince him. Haha. Now he's a HM fan too!
I have an '06 2.5 beetle. About 5 seconds after starting, the coolant light turns from blue to red. I turn it off an restart, which currently does the trick. I went ahead and ordered the CTS.. thanks for the video.
+Michael P that sounds like maybe coolant bottle issue
I don't like the phrase fail. As if they are to last forever. These are parts that wear out due to use. His information is educational and very instructive.
Please excuse the long post. first of all, Many thanks for the Video, it really helped me resolve an issue similar to what you described, but i would love to get your comments on the subject, i have an Audi A6 C6 2.0TFSI 2008, a few months back, i noticed that the coolant gauge cluster was not working. and since i still maintain my car in the dealer, i took it for inspection, once they had a look at it, they found a code (forgot which one) and they cleared it, the gauge started working again. On the same day, the gauge failed again, so they had another look. after a full day inspection, they replied that the issue was in the ECU module. their assumption was based on the fact that gauges are working fine (they tested them), the ECTS was working fine, since even though the dashboard gauge was not working, the ECU was still able to read the temperature and start the fan accordingly when it get hot, and that all wiring within the car was not short circuit. it was not a good news for me. so i did a few research, and i watched your video, and next day i came back and i asked them to change both ECTS (my car has the 2 wire model -black), and to change the thermostat also (since it was partially stuck open). so far 3 months passed, and its still working. what do you think? i have asked other audi service shops, and they replied that similar cases were noticed to other customers, but with different resolutions types. one of the service shops told me, that one customer changed his ECU module, but the problem came back and he just gave up. i know the saying (if its not broken, don't try to fix it), i just want to understand, in the 2 wire ECTS module, how is it possible that the ECU was able to read the temperature changes, while the gauge cluster was not, if its the 4 wire system, its logical, as there are 2 signals through 2 separate channels were one of them could fail, but on the 2 wire system, how its usually working?
Hello Charles my gauge shows 190F but my OBD live data shows 230F. Can you suggest what might be the problem?
Just had one done at VW dealership on 2014 Tiguan....360.00 and I had the new one with me. LOVE my VW.
I recently replaced mine on my 1.8t Polo GTi and I immediately noticed good fuel consumption so if you have this fault I recommend replacing it asap.
I would not believe how much trouble this sensor could cause, i didn't pay attention to it as it is small and cheap.. My symptom was a pretty hard start up with a rich mixture, especially on a warm engine after a 5 min drive. I started replacing tps, cps, idle air control valve, map sensor and still no luck. Fuel pressure was ok. One day i decided to unplug the coolant temp sensor and improvise a warm engine start by connecting a 400 ohm resistor and voila.. the engine started right up and running happily. I replaced the part and the problem is gone.
It’s crazy!!!
Can this cause an engine overheating?, currently have a similar situation but far from home to fix it?
Thank you this video helped a lot and was more than informative. We need more in depth people like yourself
+Adam Landry glad to be able to help! :)
+Adam Landry glad to be able to help! :)
The cts in my alh was actually reading about 15% higher then actual temp. It’s cold out so when warmed up the gauge was right in the middle seemed normal but when I go to start it in the morning the glow plugs wouldn’t turn on for more then a second because it thinks it’s warmer outside.
Would a bad ect sensor also prevent my cooling fan to function at all on my b5.5 passat 1.8t?
Love your channel btw.
thank you
I've had a no start issue with my 2002 vw jetta tdi (manual transmission) for the last couple of years. After sitting with a charger on the disconnected battery for variable periods of time the car would start and run fine. It was a crap shoot whether or not it would start a second time. The instrument cluster warning lights would flicker and sometimes there would be clicking of the relays under the dash. Recently, the temperature warning light started intermittently flashing on and off and the same symptoms as described would occur and the car would not start again. Today, I replaced the temperature sensor and after replacing the coolant that I lost in the process I started the car and let it run for a couple of minutes. It started and ran fine as usual. I was able to stop and start the car multiple times without the warning light symptoms, clicking of relays, etc. I'll see if the the coolant temperature sensor was the problem in the next couple of weeks. The sensor is the green, four wire type. Thanks for the intelligent videos!
Failed on my B6 at the time. Had the meter fall down and pop-up again. Was gone after replacing.
Now looking at replacing the one on my A5 B8 as it's not running all that well when cold and running under 2K rpm.
Good talk. I'm always looking for information on how long parts usually last, under what conditions parts fail or wear out sooner, how to check a part for failure, etc. Thanks for the failure info on temperature sensors.
Charles, you are true PROFESSIONAL!!!! Thanks for sharing your knowledge!
Quick question, on my 2012 VW CC, it runs rough at cold idle with random misfires. At 39 degrees Fahrenheit it reads 3,930 ohms. Once it warms up all smooths out. Temp gauge operates normal. I'm thinking temp sensor?? What do you think?
Do you have a video on how to change one?
.
thats exactly whats going on with my 2001 audi allroad! thanks
2001 beetle 1.9 coolant migrated in the wires causing a no start. Waiting on the new harness now. Hope it works!
Hey humble man. On a 2015 gti, could a bad coolant temp sensor cause the car to stall at idle? It's increasing fuel pressure high AF before it stalls.
Excellent video! $15 part when salesperson wanted me to replace the starter!!
Dealership wants over $700 to replace it and the plugs.
thanks for the tip i have just ordered the sensor i have a bad coolant flange and working also on the lower arm suspention on a 2002 new beetle thanks to your video of lower arm with polyurethan i will réplicas both of them
On my mk4 TDI golf. I have the 4 pin. The two pins that went to the cluster worked fine, guage was perfect. Two pins went to the ecm and it cause a no start in the winter due to the glow plugs not working. Took for ever to figure out. Forums said to unplug it as see if the glow plugs lights stayed on for 30 seconds and it did. That means bad sensor. Replaced it with a green one and it was perfect.
Hi Charles, where is the repair shop located??
Hey charles, great video! I've been getting what I think is vapor lock, and a check engine light for the coolant temp sensor. hopefully that will correct it. thanks for the video !!
aaaaand, I dropped the clip into the engine compartment and I cant find it
I bought an 2003 vw gti with a check engine light, it was hard starting, and stopped starting, i got a cel for a short in the ect, it was a light green sensor that failed , they're cheap and easy to replace though
Dude, Thanks alot. Ive been having an issue with both of my fans staying on for over 10 min after the car has been off. i recently got a CEL took it to Autozone and the told me with was ECT. After watching your video ill be changing it for sure. thanks!
My parent's 1.4 Polo SE from 2010 has had this issue for a few years now, so this seems to be the part at fault, and unfortunately we are suffering the issue where the vehicle just will not start at all when it gets very hot, as the car isn't used to high ambient temperature here in the UK, when it reaches above 30c outside the engine will be tempromental causing it to fail to start, so I will look more into this but I believe that is what it is.
If you have time, I'd love to know why there's 2 sensors right next to each other on the water distribution flange of the 2001 Cabrio I'm working on. A green 4 pin, and a white 2 pin.
@humblemechanic was really sad when you didn't cover the major issues that a faulty ECT can cause a TDI...... Glow plugs won't engage if it's bad, even if it doesn't show a code. You can unplug it and your glow plugs will work again to start a TDI car when it's cold. A bad ECT will also cause a TDI to run so rich that out won't start or run without smoking and choking you out. It would be nice to see you make a separate video labeled "TDI ECT problems" or something similar covering all the possible and common issues. Thanks a bunch either way, great video for gassers for sure!
hi Charles, thanks for that support. But kindly help me on this as well, have a Passat 2006 with a BZB engine but having a Random misfire in all the cylinders yet the coils, spark plugs and injectors are all new. It goes on and gives off dirty exhaust. Would you think that the problem could be with the coolant sensor or something else because we measured the compression for all the cylinders and they were fine.
My mark 4 (1999) Golf indicates a coolant temp at around 60 degrees while cruising in cold weather (about 10 degrees ambient or lower). Noticed this after I replaced the radiator after a minor crash. The new radiator has a higher fin density. Could it be that the new radiator is too efficient?
Joachim Hillestad only if your thermostat is stuck open or partially open.
Question, would a bad cooling control sensor even when it drops to zero will it cause the cooling fans to turn on??
My wife has a Mk4 (Type 1J) MY2000 and it is the 1.6 Comfortline. We are having problems with the car making a backfiring noise (noise is local to the engine bay...'buck' noise).
I have just replaced the coilpack as I've seen sparks jump from it to an adjacent spark lead. Spark leads and spark plugs are replaced after a dead No. 3 cylinder lead was discovered.
With the coilpack now replaced i.e. changed out VW# 032 905 106B with 032 905 106F (newer revision) and still have slight RPM instability at idle and when accelerating I still feel a type of drag as if the car isn't making the demanded power at that instant.
Having scanned the vehicle, all errors i get are the following (Note: this is a replacement lambda sensor after old was replaced):
4 Faults Found:
00525 - Oxygen (Lambda) Sensor (G39)
05-10 - Input Open - Intermittent
00525 - Oxygen (Lambda) Sensor (G39)
07-10 - Signal too Low - Intermittent
00537 - Lambda (Oxygen Sensor) Regulation
19-00 - Lower Limit
00525 - Oxygen (Lambda) Sensor (G39)
27-00 - Implausible Signal
Furthermore, the engine consumes oil, but not a whiff of smoke out the exhaust or drips. Just some on the perimeter of the intake manifold and not much trace of leaks.
Any suggestions as I'm going mad after spending ZAR 3800 ($321 equivalent) on the coilpack.
Looking forward to replies
2007 Jetta code p2181 and its not overheating, however I noticed that only one fan works with the AC turned on. Replace the ect first, then the fan? Be the smaller fan.
Geeze i hope you see this. My CTS in my 01 jetta VR6 is vibrating and feels like a little motor running after the car is off. The temp reading is fine but im going to replace it anyway. Just really weird like the connectors are frying the coolant inside.
Here’s a question! I started my car this morning after sitting for days and it had a hard time trying to start but when it did the temp was already at 190 and went to 220 and stayed there as driving
You have the best videos!
Thank you so much replacing it today so glad my son recommended you 👍
MY VW Amarok has had a cooling system issue recently where it seemed the water temp was colder than it should be. While driving the car, the temp would be around 84 deg, but drop down to 50deg C. Then sometimes go up to 93-96, but quickly back down. I have had the thermostat changed, and while running the first time, the temp steadily went up to 94deg C and was up and down around that temp, but when idling my car for a while, the temp gauge drops down to 45deg C, and while idling, it stays around this low temp. Is that normal for the temp to be that low at idle?
Dude, thank you, lucid and nooooooo waffleing!
Thanks a lot, professional and informative.
obd2 scanners got me at 200 or over before fan comes on ive replaced the air conditioning switch and the radiator temp switch im onto the cooling inlet ets ... my runs have been straight hiway and the fan seldom comes on if after i park in the drive and continue to idle the fan will come on slow i changed the fan for funny noises wasnt the best viscosity but i still i get the common read of 200 degs or more before fans ... im questioning heat prostration during trips like terrible in lower gears after long drive
Can a failing ECT cause revs to drop when coming to a stop when engine is warm? Cleaned TB and recalibrated using VCDS but issue remains.
Did you manage too fix
On the four prong water temperature sensor does one of the prongs operate the idiot light on the dash panel
my radiator fan is not stoping after switch off the engine and take away the key (even after 20 minutes). is possible to be the ect malfuntion?
Could this cause no heat inside the car? I have checked all the heater components and no luck?
2003 passat. Thank you for your knowledge.
Green vs black. Now there is grey. Hmmm..... How about a video on finding it and the correct procedure in changing it? Still, great info!
I have a 2009 Tiguan with a P0118 code high output for sensor 1. There are two sensors and they are both new as I just replaced the water pump and while I was in there I just put in two new sensors. But I can not figure out what sensor is #1 and what is #2. I want to assume sensor #1 is at the water pump but want to confirm before digging into it deeper. BTW this code existed before I replaced the water pump.
Can it be the reason for my car taking long to start when parked for long or over night?
my friend please can you tell me the wiring harness of my four wire sensor i have a audi a2 and the conector was broke so i cant find the proper connections
I have a problem, my car can´t not start in coold weather, i change the coolant sensor thinking that was the reason, but the problem persist, the car start, at the third time i turn on the key, its a 2001 jetta.
Change my coolant sender but still wrong turn over when engine hot seems like battery low or could it be the starter Moter
have a 2015 golf 1.8l hatchback. check engine light on and scan says coolant bypass valve. only 137k on vehicle. Mechanic says replace the part -4hrs labor and part is nearly 400. !!!My thinking is its the connector or sensor not the part. Dealer tells me sensor in coolant overflow could trigger check engine . Mechanic looked up and felt connnector and said it felt gummy. Is that the sensor or connector and how long should it take to replace it?
My mother-in-law has a 2001 EuroVan. No major problems with it so far. The water temperature gauge does not move. The fans come on as soon as you turn on the car. The heater never starts blowing hot air it only warms up a couple of degrees but the fans continue to run and the motor does not overheat. Could a coolant temperature sensor cause this or is it a bad thermostat? Would really appreciate some help with this. Trying to do something for a mother-in-law!!! Merry Christmas
Is it possible to have both a code for this sensor and the cooling fan circuit at the same time and it only be the fans? I had 2 codes. Changed this little guy to the green one. Had a green one in it, but who knows how old it is. And it was corroded a bit. I still have both codes. Realized one fan is coming on. The other isn't. The one that is on is the secondary one that comes on second. Its stuck doing all the work. I'm thinking maybe the fan module? I was thinking of buying the whole fan assembly with both fans and module. The temp has only thrown a red light once but Temp read don't match the actual temp. I'm thinking of putting those fans in and a real temp gauge. I hate that there isn't a gauge.
Help!! Where is the ECT located in 2012 Jetta GLI? Thanks.
Hi brother
I keep getting randomly fan kicks of and rpm goes off from 850 to 1100 even in cold could it be coolant temp sensor the temperature shows okay
Hey man! I just found your videos and they rock. I have a MK4 question if you don’t mind giving me a hand. As soon as I turn my ignition key on my fans start. Doesn’t matter where the knob is(I.e. feet, face, defrost, ect). I’ve unplugged multiple points such as the coolant temp sensor(working btw) the high pressure ac sensor, ac compressor, and they will only shut off when I unplug the FCM. So I ordered one of those but just wanted to run past you!
I have an aeh engine. Does it have two coolant temperature sensors?
Mine is hopping all over the place intermittent 2.0 TDI 2008 PD non DPF every few seconds, is it an easy replace, already threw a code.
I have 2013 Passat 2.5l changed the over flow bottle and flushed the coolant. Now light comes on says add coolant but bottle level is fine and temp stays at 190 degrees. Any help appreciated.
My fans don’t turn on when temp rises but as soon as I turn off. The fans go on. Can the sensor cause that ?
hey Humble mechanic I have a 2013 Jetta 2.0L. I have a ECT code P0118 (G62) sensor. On top of that its keeping both my AC and rad fan on at all times full speed.
Charles i could really really use your help. So. My mkiv GTI VR6 coolant fans will not come on. I swapped a new motor in and haven’t been able to fix them yet. They worked fine before. I’ve replace the rad fan coolant sensor on the radiator and the fcm. Still no luck. Fans will come on with ac and if I jump the connections both high and low speeds work. I’ve checked all wiring and I can not figure it out. Please help🥺
My bjb 1.9 has 2 sensors, one on bottom of rad and the other on side of block above gear box!?
I could use some help i’m swapping in an ALH into an 87 cabriolet I’m trying to use the factory coolant sensor that’s a four pin with the wiring from the cabriolet which is a 2 pin but not sure if it will work
I have replaced ton's on those sensors the cars that are not fun to replace is the v6 or 4 cylinder Passat or Audi the ALH TDI are some time stuck in the Aluminum housings (manual gear box only) the easiest are the 2 litre 8 valve engine the sensor is upright and you loose almost no coolant have you notice when a car that has the original temp.sensor on the black ones there is always a yellow paint dot on it .
Mine actually failed and reported a higher temp reading than normal, scared the crap out of me.
Can there be no code and be bad? Sometimes the 1.9L beetle 03 will not start, acts like a fuel pump problem with around 140,000 miles. Please help, thanks
Thanks so much but i think i have a different problem when i buy new temperature sensor for my vw polo bky engine it's struggling to start in the morning. When i put the old sensor its start normaly
But the problem with the old sensor the gauge is always low
Cooling fan runs constant whether cars running or not. VW 2012 Tiguan S 2.0 with 97,000 miles. Besides the cooling temp sensor what else could be causing this problem. No error codes or even engine light on. For now I disconnect the battery when I stop. Please help.
I have 2011 Tiguan 2.0 just wondering if engine coolant temperature sensor can be affecting my cooling fans coming on and off
Hi, my passat 1998 water temperature is not rising to 190 f just stand between 4-5th lines at the Gauge
I’ve got a golf MK4- once warm it looses power - do you think that this sensor would be a possibility? I’ll order one - but I think it could be Lamda sensor related -? - it doesn’t have any error codes :(
Could be either one. Any faults?
This is an ultra common failure
I have 2011 Passat tdi I am just wondering if the coolant sensor will make my heaters blow hot and cold air. What I mean is the heaters am going warm on stand still but when I rev the car up the heat starts to come out hot..any suggestions out there please..
Any thoughts on tail lights and front side lights not working. changed bulbs and fuses. it started with right side only
On an A4 b8 2.0t tfsi is the engine coolant temp sensor on the water pump unit or at the back of the engine? My temperature gauge goes from to center to one notch above and back down and back up. I can tell it's the sensor but people say its in various places. Please help.
Hey charles i have Golf MK3 1.4 what is the right temperature sensor?
Doubt I'm gonna get a response any time soon, but worth a try. Would a bad temp sensor cause the fans to come on immediately after a cold start, and cause the car to react as if it's already warm (no high idle to warm up) 2013 Golf R
Did you ever get this sorted out? I’m having a similar issue
Where is the sensor located on a 2013 Volkswagen Teague one?
Hi,
Please help!!
I have the problem with engine start when it’s warm.
I read on specific forums that the issue can be this temperature sensor.What do you know about this?
When it’s cold it start perfectly,but after the engine is warm ,if i stop it, it will not start anymore, i have to let it for about 20-30 min .
VW Touareg 3.0 V6 year 2006.
Thanks a lot in advance!🙏
I have a golf iv and gauge stays normally 90°C but the fan operates around 93-95 is that ok? Ive noticed the gauge moving slightly above 90 every time the fan is going on
I am struggling with this. ODB2 scanner shows my coolant temperature is at 103 degree C. Temperature gauge in instrument cluster show 90 degree C (right in the middle). Is this normal? my car is VW Passat B7 2011 (1.8 TSI)
Hi I have questions I have Mk4 Jetta 2001 tdi and i start having problems starting car when temperature is near cold car will have long cracks befor start but when is cold below 32 start with no problem also I noticed unplugging coolant sensor start with no problem. One more thing when is near cold glow light inside don't stay for long comparing to when under 32. Can you please help Thanks
I installed the sensor but coolant shot out of it !!!!! Would you
Know why?
good video i replaced the sensor and wiring and it works but i still code?
I like how he loved this but didnt fucking answer?
not sure if my is inaccurate, but I put water and when the water start boiling and it's stays at 90c then suddenly jump when I see steam come out of my car after a while. then yet again it could be elevation. 1,500 feet. then yet I haven't replaced it in a Long time
A no start you say? I've been trying to figure this out for a year; battery, starter and everything else I could swap quickly and test. 1.8t mk4 gti '04 usually takes between one or two cranks or a straight clunk then a crank then a start. Always starts no codes and temp sensor never drops out. Does it on cold and warm starts all alike. Opinion?
I’ve just had this issue. Changed the sensor in five minutes but I still have an intermittently working temperature gauge and I’m totally stuck now
Hi HumbleMechanic, I got golf 1.4, patrol, 2008, manual, 94K mileage, for last 2 years or so my golf dont start on a scorching sunny day, it takes 15-20 attempts (around 10-30 min) before it'll eventually start, no problem whatsoever in winter and onn summer nights, on advise of a mechanic i've just changed Temp sensor ( 2 pin, aftermarket, not a genuine as i wasnt sure the cause of the problem), but problem is still the same, kindly advise asap please for the next step. Many thanks
My fans on 01 beetle stay on constant. Replaced the relay 127.00 and still they stay on. Could it be this sensor ?
Does the coolant temperature sensor give the reading for the coolant temperature gauge on the dashboard, in a golf mk 5?
Hi, I know this is an old video but I need some please. So I replaced the radiator and fans on my 09 Rabbit. My fans do not work and overheats at idle when sitting in traffic for about 10-15mins. I checked relays and fuses. They look fine. Is there something I am missing? Could it possibly be the part you are talking about in this video?
