Hummer H3- Clutch fan problem (Metallic noise)
Vložit

- I had a weird noise coming from the engine. Started a low metallic clicking noise to a really loud one.
With the hood open, it sounded like a valve problem.
When I looked at the belt tensioner I realized the problem wasn't from the head but from the clutch fan and the tensioner.
Here is the link to Rockauto if you need to order a clutch fan for you H3 2006: www.rockauto.com/en/catalog/h...
And here is the link for some belt tensioner that are available: www.rockauto.com/en/catalog/h...

Thank for video!
Good job on fixing and preserving this unique car/truck.
I possibly have same problem, for over few months already, when I start car there is this metal noise as you describe, after a while it goes away.
And I see tensioner jumping around a little!
I have belt, tensioner and idle pulley ready to go in, but not fan clutch, did not think about it, will change belt and rest of gang, then will check on fan problems.
Also, I had a more noises coming from front end, steering fluid container was low, added a little and noise came down.(it is due for flush and clean up).
Hey, thanks for the comment!
If you remove the clutch fan try to spin it with your hands. If it turns easily it means it's bad and needs to be changed.
*** BUT even if it is hard to turn it in your hand doesn't mean it is good!
At least it may help out, but from what you are telling me, this is exactly the problem I had with the clutch fan. Was little at first and it seems to go away after the engine was warm....until it became constant, no matter how long I was driving.
For the second noise, is it more present when turning or it is always there?
Start your vehicle and leave it on the park, then turn your steering wheel left and listen carefully. Listen for a winning noise. then stop turning the wheel and listen if the noise dies down.
Do the same by turning the steering wheel to the right.
If it makes that noise and dies down when you stop making pressure on the wheel by turning it is related to your power steering.
It could be a bad pump, low on fluid (usually the noise like the is because it's low on fluid.)
@@probonomechanic Changed belt, tensioner and puller, all noise is gone! Tested clutch fan, it actually turned pretty hard and when I rev up even in cold it turns pretty aggressive. My mechanic told me that it is not too good. Changed steering fluid, sounds better, there is no weird noises coming from it now.
@@LatvjuAvs Hi, That is great news!
Happy it was just that and nothing major. For the steering fluid, the old one may have been contaminated with water or gone bad.
Random question, did you change the tensioner at the same moment that you did the power steering fluid? I'm just curious if the noise came from the belt not properly gripping on the pulley of the power steering.
But for now, enjoy your ride! I'm about to post a video soon for the alternator. My battery light came up, so I'll make a video about it and at the same time show you how to remove a rough idle (well, one of the factors that can cause rough idle!)
Thanks for the update, I appreciate that!
I have the same problem. I thought it was the belt tensioner making noise as it jumped a t idle. I didn't think to check the fan clutch. The sound goes away at high speeds and just even driving at low speeds after it warms up. So it actually makes sence it could be the fan clutch. I was like you also scared it was a lifter or valve smacking the piston. Great video and thank you! I will keep you updated on my progress!
Keep me posted!
My only regret was not recording the noise. I was just starting the channel and it wasn't a reflex at that time.
Keep me posted!
Thanks.... I have the exact same Problem
Happy it helped! At that time, I wasnt expecting to do many videos. And I didn't record the clicking noise before doing the job.
If you go get the tools, be careful if you use the cheaper brand, the tool will be a bit snug on the bolts just make sure you got it in the right position and tight in place!
I hope you reply
My 07 H3 cuts off when approaching a red light or stop sign. It’s stalls bad when I’m not giving it gas. Any idea on what’s wrong with it
I'll ask a few questions to help me try to figure what could be the problem.
How was the idle when driving? Did it feel as if the engine was strugling to move? Did you do any OBD2 scan to get a codes? (To scan you can use a 10$ scanner to get the codes).
Do you have a sunroof/moonroof on your H3.
There are a few things I can say to test which doesnt cost anything.
1: check oil level in engine, if low the engine can land in limp mode.
2: remove the throttle body and air box. Check the throttle body. If it is blacken and full of residue it will need to be clean.
3: if you check the intake air warmer box. There is a short hose that connects on the intake manifold. That hose can crack or become loose. It will make the idle barely impossible to run.
4: if you have a sunroof, is there water building up in your sunroof? You can open the sunroof to check. The side pillar plastic cover can be remove to check if water is dripping due to the build up of water. If the carpet is wet, it can be another sign of water build up. It cause humidity in the ecm connection. Sometimes just cleaning the sunroof drains to prevent future problems and disconnect the ecm to let the connectors dry it could hopefully fix it.
I'll give two links below for the small hose and how to reach the throttle body.
Finally, last question. Did anyone work on your H3. Repairs, parts replacement, maintenance. Anything.
A loose battery terminal (connection) can do that.
Here is the video for the short hose located on top of the engine: czcams.com/video/AidQa7VZ2do/video.htmlsi=bMHn0j7v0W8eA8WN
This is the video that shows how to clean the sensor and throttle body. I mostly want you to check if it is in dirty: czcams.com/video/dPsy4U6hM8U/video.htmlsi=2ZmLGYfUBnryvF2q
My hummer’s temperature stays between 3/4 and 1/2 after I changed the water pump and thermostat. Any thoughts on what it could be?
When you changed the thermostat did you use an oem or after market. Weirdly the oem open at a higher temperature compare to the after market.
If i remember the oem os about 195 degree and the after market is like 175-180 degree. If you bleed your system and the fan is working properly. Is could be a problem different problem.
Why did you change it? Was there a problem?
@@probonomechanic I’m not sure the temperature of the engine. But the reason we changed both the water pump and thermostat is because the it was marking between the 3/4 line and the 1/2. The parts are after market. My mechanic wants to change the coolant temperature sensor. What do you think?
Hey, sorry for the delay. I just saw your reply!
Well, it does seem high. They usually stand between the 1/4 and 1/2.
It can be tricky it could be a few things.
Do you know its full history or you just bought it?
Does the radiator seems in good shape? Like the metal fins on it.
Did the transmission got changed lately? Sound weird and some people will maybe not agree with me but a transmission that overheat could damage the radiator since it share the same radiator, instead of the smaller secondary.
Any loose of power in the head? Or loosing oil or/and coolant? (Even if its just a bit)
Check to see if you got smoke coming from the exhaust.
Could be the head gasket.
The sensor isnt a bad idea since you remove a potential problem.
When I'm not sure I start with the cheapest options first and go up. (When i can't find anythong with the diagnostic)
@@probonomechanic I put the OBD scanner the engine’s temp while sitting is at 207°F and 203°F while driving. I’ve recently bought this Hummer, the transmission was recently changed by the previous owner.
Actually those numbers seems fine. If it stay there at low load and high load, I believe your system is fine.
As long you don't reach in the 220, I wouldnt worry too much.
If you got the 190 degree thermostat you seem in a decent scale.
Is your H3 is a 2007?
Where did you get the tool kit from
Hi sorry for the delay!
You can find a cheap model with the size on amazon: www.amazon.ca/8MILELAKE-Foreign-Domestic-Remover-Installer/dp/B07Y56DRNK/ref=sr_1_17?crid=2Y74EIITI8KRB&dchild=1&keywords=fan+clutch+removal+tool&qid=1620395632&sprefix=fan+clutch%2Caps%2C183&sr=8-17
Princess auto as a similar for an extra 10$ : www.princessauto.com/en/5-pc-fan-clutch-wrench-set/product/PA0008491987
It depends where you live. Call any part shop close to your place and ask for a Clutch Fan removal kit. You'll need the 36 mm wrench with the 76 mm fan pulley holder.
Just a warning, those are the cheap models that I just sent you. They will be a bit loose, just be careful when working with them and making sure its properly in place!
Hello a fb mechanic replaced my clutch fan then it started to sound too much air
Any help plz
Hi,
I would need more details. Some propelers are really loud. It makes a wind noise.
Are you saying that there is a sound of a lot of air being push under the hood or there is another type of sound coming from the fan?
@@probonomechanic yesterday it was like 43 degrees then it would make alot of air then after 2 miles it was good but today its too much air i think its not normal idk
@@probonomechanicfan doesnt stop you press gas and i hear more Air
So it is just the fan propeler under the hood that makes the noise?
Don't worry, it is fine. My H3 does the same.
When you start your vehicle it will be louder, and as you drive (maybe 5 minutes) the fan propeler seems quieter, right?
If it would keep going for a whole drive, maybe the clutch fan is damage, but of it stop, its fine.
Hope it help!
@@probonomechanic thanks man alot
Man i wish we could har your sound. Mine is louder with the oil cap off. Reallysounds like a valave or rocker but the noise is faster than the cam spins. Im gonna go pull this fan off and start the truck and see what happens
Hi, I just saw you comment.
How did it go? What was the problem?
Dude no no no loosen bolts whole belts still on it.
play the noise next time and it would be a 5 star vid
Yaaaaa, hindsight 20/20 hahahah
I didn't any videos in the early days of the channel...but now it feels like a no brainer.
It's on my list of things that needs fixing on the channel haha
How about a video That ACTUALLY shows the problem(sound) and after your procedure THAT YOU NEVER DID. All you did was describe how to remove a clutch fan and NOT identifying and eliminating a problem.
Thanks for nothing
Hi,
Sorry for the delay.
What happenned with your H3?
The front differential passenger mount went
@@ericwilderness5074 ouch! Were you mudding?
Worst that I got for the front diff was the passenger side outer bearing eating the axle. (But the seals were gone when I got mine. Pretty sure it was the main reason for the whole scenario)
