Engine Bay Squeak / Squeal

Wait, wrong people in my engine bay?

Honestly, I can't believe no-one slipped in a lube joke sooner s:roll: :roll: s:roll:

Quote from: "jinxedkitten"TALCUM POWDER!

Big thanks to ChrisGB for his suggestion of using French chalk to dry-lube the belt. I suspect replacing other parts will also have helped and I don't regret it as they'll last a whole lot longer now and I have learnt a bit along the way.

She is now silent as a silent thing. Chris, you are a legend.

s:bounce: :bounce: s:bounce:

OK, running the risk of inviting even more lude and crude comments, s:lol: :lol: s:lol: which are hilarious by the way s:lol: :lol: s:lol: , how exactly did you apply the french chalk? Did you liberally apply it all over, or were you more precise than that?

jinxedkitten · February 20, 2015, 22:21

Due to slight missunderstanding, Talc isn't really quite right. Initially I took a handful of talc, sprinkled a bit on the outer side and a bit on the ribbed inner side (ooh matron) then smoothed it around as much as I could reach.

However, Chris had actually advised using something more like tailors chalk, so tomorrow I'll rub a bit of that on both inner and outer sides if the belt.

The talc's anti squeaking properties seem to wear off after a while, (although its a whole lot better than it was!) I'm hoping the tailor's chalk will last better.

Small girl hands help with the applying...

Doesn't all of this just seem to be curing symptoms as opposed to the disease?
I've certainly never heard of chalk being a normal service additive to belts s:)

s:)

Maybe the belt is just crap and squeaky? Another belt

Joesson · February 21, 2015, 10:05

As it would seem that we are now of the opinion the squeak is not the symptom of a problem, may I suggest turning the volume control of your radio/ CD player in a clockwise direction until the symptoms are no longer audible? s:wink: :wink: s:wink:

You can just use blackboard chalk and put the stick under the belt when its running and move it up to the belt and let the belt run over it as it goes round, keeping your fingers out the way. This is not a permanent solution but does localise the problem and you live with it or change the belt for another make. Thats what I did in the past with another car.

I know someone that attempted similar....and lost a finger. I wouldn't be advising this lol

No thanks, I like my fingers!

Shnazzle, at the moment, yes I am settling with curing the symptoms not the disease, I need to wait until I my funds recover enough to be able to spend more on disease cure research. As far as I can see, there are only 2 more thing I can do. Replace the water pump, and replace the belt, but as it squeaked both with the first belt and the belt that went in 2/3 weeks ago, I'm not sure that will help. I'm running out of ideas and throwing it at a garage asking them to find the issue is likely to get expensive.

In the meantime, I'll settle for being able to turn up to the funeral without a nasty squeal to add to everyone's day.

ColinC · February 21, 2015, 17:15

Its certainly a good idea to keep your fingers out the way.

StuC · February 21, 2015, 17:51

Perhaps could borrow another yellow for that day.

ChrisGB · February 21, 2015, 19:01

Blackboard chalk is not the same stuff. Fingers near moving belt? Not wise. French chalk as a service item for belts? One of the oldest fixes in the book.

Changing the belt has already been done. A bit of the right lubrication on the belt will work once it gets spread along the whole length. It will need topping up occasionally. Often these squeaks happen because a bit of corrosion on one of the pulleys damages the edge of the belt making it squeak. Short of changing them all, it is a cheap and simple partial solution.

normanh · February 22, 2015, 09:21

For French Chalk read Talcum Powder make it smell nice as well hehehe, graphite can do a similar job but its dam messy.

Experimented with chalking it this morning, but all it achieved was to partially scrape away a layer of crap on the belt and get the chalk covered in oil. Will have to clean the belt before doing it, I'll have a go with some degreaser next weekend, back to talc in the meantime.
Lube fail s:(

s:(

jinxedkitten · March 1, 2015, 20:03

I degreased the belt a few days ago and have since been applying the French chalk. Goes on fine now the belt isn't covered in crud, although it's tedious to chalk a bit, turn the engine over to move the belt along, chalk the next bit etc... I've been applying it every day before I use it and so far, it only sporadically stops the squeaking. The talc was doing a better job than this is.

Short of replacing the waterpump, the only thing left is maybe the crankshaft pulley s:scared: :scared: s:scared: ...?

Time to turn the radio up!

That is to say " Turn the radio up" s:wink: :wink: s:wink:

I suggest that this noise has become a real irritant to you JK and your persistence in trying to find a cure is laudible, but try just leaving it alone ( with the radio at an elevated level) and then have a listen again in a few hundred miles.

Joesson · March 2, 2015, 11:46

PS
Some time ago a friend had a 2(CV) with an irritating squeak.
A friend of the friend was a 2 ((CV) Specialist and he simply poured a trickle of water onto the Vee belt with the engine running.
The squeak stopped instantly!
That was a friction drive Vee belt, not the toothed drive belt that we have on our 2.
But each tooth as it engages must create friction!
So maybe a trickle of water would help.

jinxedkitten · March 2, 2015, 12:31

Yeah think I'm just going to have to live with it for now! I can just drown it with the radio and the hardtop on, but soon as the HT comes off, I might get on the case again.
I will try a small trickle of water and see how it goes. Whilst its running or while its stopped?
What are people's thoughts on crankshaft pulley replacement?

Try the water boarding! With the engine running.
Only a steady trickle of water, it should find its way to both sides of the belt.
Be sure to stand to one side to avoid any spray.
It won' t hurt anything and any over spray will soon dry off.
The crankshaft pulley should be seriously fixed, I can' t envisage how that could make a noise other than by conflict with the belt.

jinxedkitten · March 5, 2015, 09:17

Hmm, so here's an interesting thing.
Tried the trickle of water and it worked temporarily.
However, I then noticed the aux belt is not spinning straight, but oscillating side-to-side. The tone of the squeak had changed of late to a more rubbing noise, but I didn't think much of it.

I've tried tightening the idler pulley bolt, but I'm only a girl and have no torque wrench and couldn't get it any tighter.

Could the long bolt holding the pulley in be slightly bent, causing the pulley to spin off-centre?
There doesn't seem to be too much movement at the pulley side though, and none at the alternator end...

Joesson · March 5, 2015, 09:38

Glad that the water made some difference, albeit temporarily.
I suggest that would indicate something wrong with the belt.
I believe only two things would affect a new belt in this way, tension or alignment.
Tension is determined by the tensioner device, and I ' m assuming that is doing it's job.
You have noticed some misalignment so perhaps that is the problem.
A torque wrench would serve to give you a specified tightness not an increase in tightness as such so unlikely to be the cause.
If you can see some side / side movement of the belt that could be "it".
What /where " it is is the next answer you need.
My bionically assisted hearing can' t help from the soundtrack!
Maybe it would help to remove the belt and refit, I ' m unsure about changing the belt direction, I believe it is bi directional and I understand it is relatively new, so that would be my plan.
