Hi
This car came to me with a few issues... Multiple faults in the ECU, really poorly and dodgy wiring repairs... and the radiator fan always on... from the moment the ignition was turned on...
Follow me on this video to find out what was the problem and how to resolve it.

Useful and informative - some of those o2 sensors have a different multi plug but share the same sensor - “Bosch to name a few” maybe someone replaced it and bastardised the plug
Possibly...
I never know when car come to me after being around....lol

You need to make a video of how to change the heater matrix of this car. There is not a single video anywhere. Ive changed everything on this car and it still over heats and also loses power (Acceleration is bad) the only thing i have not changed is the heater matrix.
The reason the fan kicks in higher than 100 (usually 108 give or take on these - I've seen 115 on some cars) is simple physics. Cooling systems run under pressure, this makes the boiling point higher. Add coolant into the mix and this also lifts the boiling point (as well as lowering the freezing point). 120 degrees plus for boiling point is not uncommon. The gauges always read 90 for the driver so as not to frighten the people that didn't listen during physics at school if they did it. Either that or it's just too long ago to remember 🤪 Sometimes on Vauxhall's this can go the other way, the fan never kicks in under normal driving. The reservoir cap looses it's internal pressure seal and the coolant therefore boils at a lower temperature than what the ECU is waiting for. A Vauxhall with a temp gauge is a thing to behold as well. To be fair on that car those pipes did look a bit stressed. Like a remainer the day after the referendum 😁
Well said.
👍👍👍
With the code 59 etc for windows always set the up position first if the cable is stretched and you send it down first the slider has a higher chance of popping off the bottom of the rail
Just start with basics...
Very good advice , always...
👍👍👍
Great content.
I had to change an o2 sensor on an astra the other week. When i loosened it it took the threaded piece out the cat itself... Had to weld that back in before fitting the new sensor. I thought you may have had the same fault there...
Excellent video, as always 😄 only one correction: the radiator temperature sensor is placed on the radiator right hand side (just the same as the corsa D 1.2 you have shown few videos back). The connector that you have shown in the video is the thermostat heater 😉
I know... well spotted!
There is a follow up on this one... stay tuned!
😉
Thank you for watching and for your comment!
@@LMAutoRepairs usually the heater inside fails, and the fan will go at full speed with a "code 89" showing in the dash. I've changed many of these.
1 plus 1 is 2 . You think logical and that´s why every repair video is interesting .
Thanks!
👍👍👍😊
hehehe we knows those cars here in US as chevy cruze. The computer by default turn on the fan high speed when flag trouble code in the cooling system. Heater element at the thermostat, any coolant sensor problem computer turn on the fan high speed. I see p0101 causing the cooling fan to go high speed too. I don't know what's General Motor mentality by running the fan to blast everytime money light go on. Good video.

Thanks!

Cool intro Bro😎
It was not only the Engine light & the Spanner light, there was another light that's always on, usually when the customer has to drop the car's & that's the famous Low Fuel ⛽ light🤣🤣🤣Lol
That's a Tech's life😉
Thanks for sharing Bro👍
Very useful information in this video to learn from👍

There is that... lol
Fair enough...
👍👍👍
I had this problem, radiator turned as soon as I started the engine. I then replaced the thermostat and the fault went
👍👍👍
Thank you for watching!
I would say yes to that
Very good and clear information given
😊
Thank you!

Love watching your videos, great job!
Thank you!

Congratulations on everything you do!

Thanks!
Thats happend to me last year,,it was the thermostat,,changed it, and all is ok.
👍👍👍
Super film i praca. Pozdrawiam
Thanks!
Start with the basics , yes we should , thanks a lot ...
😊👍👍👍
Professional job. Like always 😃😃😃😃
Thanks!
👍👍👍
you've just saved me 70 pound on a new stat, I was almost certain that the sensor on the stat was broken, I'm i right in saying the plug on top of the stat is the temperature sensor plug?. I'm not really that knowledgeable when it comes to cars but have done a little research on the problem, but this video has been very informative and the fuse indeed seemed to be my problem too except when fuse has came out a little bit and contact wasn't their and was not blown somehow, but will most likely change this as might of been damaged due to not been in correctly.
desired etc with blown fuse was -40 and radiator temp sensor showed -40
😊😉
There is a follow up coming...
Thank you for watching and for your comment!
Like ur videos and gets lot of knowledge thks sir
😊👍👍👍
Nice vídeo... That sensor makes the fan kick in way to late 105 celcius its to high it should be programed to kick the fan at arround 80 celcius kind of risky for opel to disign that thing like that... in Portugal in the summer that head gasket would blow fast..
All to do with emissions etc...
Not sure, but probably is the same on the Opel in Portugal...
Thank you for watching and for your comment!
105 c is round about normal for opel but the dash gauge only reads 90c .
Check fuses/relays see this a lot on Astra H and is usually all related
👍
Thank you for watching and for your comment!
I think that external temperature sensor is broken too. It's summer in UK.
🤣🤣🤣
It is now... but this was recorded about 8 months ago...😊😉
Thank you for watching and for your comment!
I'm having a problem connecting turbo pipes. To inlet manifold on astra j 1.4turbo Manifold behind the engine. Basically please can i see how is connected Astra j 1.4 turbo A14net engine petrol
This car to me seems to be fit for scrap only. So badly looked after, faults ignored and bodges. Hateful money pit 😂
The customer only brings it to you when the fan stays on? 😂
Far more problems than that to deal with....
You're brave for taking this sort of crap on, I hate it when people have already been at it and not done things right or put them back properly 😡
Or maybe the customer bought it from someone dishonest? If the head gasket had blown they just did something to stop the car overheating? 🤷
Who knows
Yes... who knows! 🤷♂️
👍👍👍👍
Very strange case and strange repair ...
Indeed...
There is a follow up though...😉
👍👍👍
Great work 👍👍
Thanks!
👍👍👍
Good video thanks.
Maybe it had an airlock and ran the old fan until it failed. Would that leak allow air into the system?
Thanks again
Possibly...
Thank you for watching!
Great work
Thanks!

Hi the fan will come on 105 to 108 I hard the same thing yesterday with a customers vauxhall zafira B 1.8 30minutes fix 👍
👍👍👍
How do you know this temp when gauge says 90 max.

Anthony ive just had my chain snd valves done my cooling fan is not coming on. It used to when i drove around just local. Spin when i got out etc. Any ideas. Thankyou for your time.
Hey Louis guess what TopDon recently had a software update and now has full time battery voltage on all screens. I guess they listened to you 👍🏻
That's great... I don't have the Artipad anymore, so can't confirm that... but is great if they did add that feature!
Thank for letting us know!
👍👍👍

What is the problem if my fan is not coming on? It used to after a good spin stay on when j got out of car etc. Just had timing chain and vslves done.
Code 59 means open then close driver door I googled it
LoL
I opened many time and did not cleared...
It was the window regulator limits not learned... as I have explained...
😊
👍👍👍👍
I don't know why people/mechanics don't start from the basics, why they don't check fuses for example but instead of that, they change everything what diagnostic machine says about fault code?? How many times we have a costumer with a box of replaced parts but none of them was required to replace... Typical
Agree...
Thank you for watching and for your comment!
Which scanner are you using
On this video, was using the Artipad 1...
👍👍👍
and my radiator hoses are a little harder. was it a problem in the head or is it a normal preasure in astra 1.4?
It is normal a bit of pressure...
👍👍👍
Hello would you know the middle wire function. I'm trying to test ths resister to see if its stuck on ? My fans running all the time Evan with no key. And only stops by pulling the fuse .iv a 13 plate astra 1.7 cdti mk 6 .I'm told its an H model . Thanks
Hey...the fact that fan turns on at 109.. is it normal..? will the car over heat on hill climb....? usually low speed fan should come on 92 and high speed fan come on around 100 that how Japanese cars work.. by the way are you UKAUTOTALK member..?
Vauxhalls are set to tun like this...
Mainly due to emissions etc...
Thank you for watching!
I have a 2013 Vauxhall Astra 1.4 Petrol and each time when I start the engine code 89 comes on and the cooling fan stays on constantly at full speed. And when I’ve stopped in first gear at a red light the engine shakes and makes a weird noise but when in neutral it doesn’t make the noise. I also have an engine light due to the thermostat but I don’t know if that’s the cause for the cooling fan to constantly stay on or do I need to change a fuse or relay can someone help me out !!
Not sure us the thermostat of those trigger the fan at all times... but there is a possibility... live data etc should help you diagnosing...
But if you know the thermostat is bad, change it and go from there...
As for the vibration, sounds like clutch or flywheel related...
Thank you for watching!
Hello . Please if you want to tell me what brand is the diagnosis?
Here I was using the Artipad l
Thank you!
Thank you very much!
Which scan tool did you used to diagnose this car??
Is it Maxisys?
I know a few... I mean, there is loads out there...
Not really sure if i got your question...🤔

How did you know the head gasket has gone?
I didn't...
I was only thinking out loud...
Signs of coolant everywhere in the engine bay, and the radiator fan was not the original...

Thank you for watching!
@@LMAutoRepairs Ahh I see 👍 thanks for the great videos
My fan isn't working any idea please
It can be so many different things that would be difficult to list...
You need to do some checks yourself, the basics to start with, fuses, relays, connections etc...
If you can scan the car, do it, check live data and perform actuations to understand and have a better picture of what is going on...
👍👍👍
@@LMAutoRepairs appreciated sir
Who would you recommend for Autel Mk908p/Ms908p?
Never used the MK, and to be honest, i have not even checked the differences...🙄
I can definitely recommend the MS...
Thank you for watching!
I'm sorry, but the question was who would you recommend?

🤦♂️
My bad... sorry...
An official Autel distributor is always your best option...
👍
Ok, Let me put it another way, who did you get yours from?

I got my one on eBay...
Can't remember the seller though...
My car done this and it was a fuse blown..2o13 astra..17 cdti..
Fan on constant an car in limp mode
Really need your expertise with my Peugeot 206 gti 180. Let me know how to get in touch
You just did...😉

@@LMAutoRepairs mostly, I need an ECM and one transponder coded
Let me know how you Coul do this

What is the issue with the car?
@@LMAutoRepairs nothing really but i would like to swap for 307 ecu to fit cruise control. Original ecu cannot handle it where 307 ecu can.
Please can I speak to someone in this garage please?
Is not a garage...
It is just a guy helping some friends...

Thank you for watching!
🤣🤣🤣 for now don't panic.
Is it better than Autel MK 908P?
How can a 10 year old car have so many issues
🤷♂️
I have see worse though...
👍👍👍
Like any car when toy town mechanics have been at em in the past. To be fair it was just a fuse (and probably a head gasket looking at the pipes). At least now its had someone with a bit of sense looking at it.
