Vauxhall/Opel Astra J radiator fan not working... or is working? Fault finding and repair.

Consider to support my channel and all the hard work put into it at / lmautorepairs
Thank you
Hi
This car came to me after had an engine replacement due to a bad head gasket...
The complaint was that the radiator fan was not kicking in when the coolant reached the 90°C...
But, what was actually wrong, was something completely different...
Follow me on this video to find out what was the problem and how to resolve it.
Hope you enjoy the video.
Any questions or comments put them below.

[@timmehlittleloud2251]

With coolant added and under pressure an engine coolant system can be 120 plus before it boils. It's usually radiator caps on Vauxhall's that cause bother, seen loads faulty. They leak and don't let the coolant pressurise then the temp for the fan to come on isn't reached. I've seen Vauxhall's that are set to 114 degrees. Dash's show running temp at 90 because that's how it's always been and would frighten most people to see it over 100. With the new bottle the system is under pressure it changes the temp. Always fit new cap with a head gasket fault.

[@LMAutoRepairs]

The coolant system should be pressurized all the time. Being pressurized, will not allow cooland to boil at 100 degrees Celsius and the engine wil run more efficient with high temperature. Grate video, like always!

The sensor on the bottle is to say the level of coolant if gets low. Does not read any temperature from that sensor. Just level. 😉

[@t0nito]

The temperature gauges on modern cars aren't really accurate and are just there to assure the driver that the engine is within normal operating temperature they actually have a really large buffer range, on VAG cars for instance when it's bang on at 90º the actual temperature can be anywhere between 75ºC to 115ºC.

Makes me wonder if someone cut the expansion tank deliberately to either ruin the engine or use that to sell them a replacement (oh look water is coming out your head gasket is gone) 🙄 there are so many idiots out there anything is possible. I think the sensor in the bottom of the tank is probably to signal that it's run dry as opposed to temperature. Super video though, another great fix 👍🏻

[@misterzee5736]

i think if you looked at the dial the temp would show about 110 right when the fan kicked in then would go back to 90 and fan would shut off. Happens on mine, same car. Currently have problem where the fan did not shut off after cooling the temp, not sure if you've come across that. Working since but haven't been stuck in traffic as I was that day. Relay? Coolant bottle looks low, no leaks around right side, but maybe water pump.

[@LMAutoRepairs]

No, ver came across that... Could indeed be a sticky relay... Is the temp dropping as you say, is it showing on live data? You might have more than one sensor... 👍👍👍

Both temperature sensors work almost uniformly. This not normal. It is necessary to study the graphs of temperature growth over time. Suspicion of a bad thermostat.

Probably someone trying to hide an overheating issue, maybe to sell the car on quick? I bought a car once that was overcooling , but also losing coollant. Checked the thermostat and it wasnt there ! Put a new one in and the car was overheating. Took it to a mechanic and it turned it there was a small crack in the cylinder head. The previous owner obviously knew this and tried to bodge it and pass the problem on to me.

[@LMAutoRepairs]

This cars due to running hot, the system get really pressurized... perhaps they thought it was something wrong, and did it to release the pressure...🤷‍♂️

[@jackb3232]

If he had previous engine with blowing head gasket he cuts expansion bottle to relieve gasses that gets in coolant. They create such high pressure to burst hoses or force coolant through vent.

[@januszderen1253]

I had similar case - Insignia, 1.8 petrol, costumer came in to me with fan problem. Fan was running all the time, no temp readings on dash. Obviously I checked for fault codes and it was one - temp sensor open circuit. Before he came in to me, car had head gasket done and before he had done it, everything was ok with fan. When I started to look on temp sensor, I was in shock - somebody cut out a piece of wire with plug to temp sensor!!! I suggested to costumer to come back to previous guy to repair it. After few days he came back to me and said that previous "mechanic" said that he isn't car electrician and he won't do it!!! Finally I fixed it, sent costumer to scrap yard to buy piece of wire with plug, soldered it on and it was fine. I don't understand why people doing stupid things like these ones. Even if he broke plug when he was lifting head for gasket replacement, why he cut out wire?? So stupid... BTW another great video shoving how bad some "mechanics" are "skilled"

[@markphillips2076]

I've had similar issues with an Astra J 1.6. Bought it with a cracked header tank, replaced it, then the temperature sensor played up with a broken wire. Sorted that out, then the water pump seal started leaking. Sorted that out, then the radiator hoses started leaking. Sorted them, then the thermostat heater (yes, the ECU opens the stat up with a heater) went. That's the connector in your video on the thermostat that isn't the temperature sensor. So far so good, the fans seem to be working on full speed, but I've not yet seen low or mid speed. Will have a session commanding them on using the lo/mid/hi relay connectors in the fuse box. On top of that this car has cam timing issues. That's another of your videos. You could have made a whole series of videos with this one car. I hate Astras now, they are too cheaply made. Too many computer modules. On a luxury car that's fine, but on a cheap car the computers and the sensors are cheap and fail all the time. I still have to investigate why the seat heaters aren't working, why the OBD port reads 1v lower than battery voltage, sort numerous earth and wiring problems and find out where the seam in the roof is leaking and seal it. This car is so bad it should go Woof!

@@LMAutoRepairs Yes, the usual thing on cooling systems: fix one weak point and then the next weakest fails. But this car has a whole host of problems.

For the fan to come in when you turn on the AC, you need to have the AC system working properly... certain faults like low refrigerant pressure, will prevent the system from engaging...

In fact, a problem of the same sort happened with me 3 weeks ago when a 2008 Nissan Altima with 3.5L came to me with the check engine light is on and cooling fans not working even when the car gets overheated. I scanned the car & I found a code for the ECTs, I checked wires (5V ref & Ground) the circuit was intact from the ECM to the ECTs, everything was good. I decided to buy new ECTs because when I plug the connector into the ECTs the car starts stumbling and it shuts off straight away and when you restart the car with (foot on pedal) it keeps running until it reached boiling temperature while the cooling fan is shut off. even with the new ECTs nothing's changed, I left the car and the next morning I checked the Live Data I found that the ECTs was reading (-40) celsius even when the connector is unplugged!. When I keep the connector plugged the car won't start unless I unplug it then the car would start with cooling fans at high speed. That problem really freaked me out and I couldn't find a path to solve the problem. Then the customer took the car back to another workshop who found that the cooling fan Relay was not working properly they replaced the relay, the problem was solved! A relay really?!!

Another case of Bogging. Car gets bought by used car dealer he only employs cheap labour. Tells the cheap labour to just get the car running to sell on quick with little or no money to be sent, chances are neither the booger or dealer knows what they are doing. That where the bogging starts. No thoughts for the poor punter that buys the shed.

Why don't you just put in the description of what was wrong and what did you do? Video goes for 36 minutes. Still no clue what your results was.

[@LMAutoRepairs]

Hi So, you watched the whole video, without skipping, and you still don't know what was wrong in this case? Why do I need to put it on the description if it is all in the video? Thank you for watching!

They must have been close to another new head gasket. Muppets

Slaging other mechanics is not very professional as well when yourself don’t look confident at what you say. You say everything is fine but your thermostat is naked

[@LMAutoRepairs]

I might not be too confident, but I learn and do things properly... I don't bodge things pretending I know what I am doing... as most of the repairs I do, I don't know what the problem is, I investigated, learn how things work so I then understand how to fix them... Nothing wrong with the thermostat by the way... 👍👍👍
