hi all, wondered if any one had lubricated a noisy heater fan in a 99 focus? its got very noisy since the weather turned colder. is it a sealed up unit or has someone on this fine website managed to get some oil or wd40 into the bearing??

yes i have done heater motor's bearings with a "squirt" of wd40 and they do go quiter,However if you take the heater to bits on the focus wouldn't it be easier just to replace the motor? for all the work involved! there cheap enough no need to buy genuine, good luck..

squirt wd40 into the intake,,, and put the fan onto full power as u squirt

if there is some sort of pollen filter, dont forget to remove it first!!!!

If the bearing is noisy, a few drops of 3in1 oil or similar would be better. WD40 will dry out over time and you'll have to take it apart again.

How will this get the oil to the bearing? All this will do is cover the propeller fan in oil and stink out the cabin. No oil will get anywhere near the bearing.

that goes down as the laugh of the year on here for me
now im off to cut some air up into 4 oz pieces :-)

40 minutes book time to do the fan on a foci so i would take it out strip it down see if the bearings were worth oiling but probably renew if i was keeping said car.

try it b4 u knock it

its a well used trick that DOES work

try not to be personal about someone over the internet....you dont know when they'll get u back

Go on then explain to us all how on earth is this going to lubericate the bearing inside the plastic box it sits in??
it's suley as said going to make a HUGE mess and smell awfull!!!

it worked for me on my noisy heater in my bmw
it worked for me on my noisy heater in the vw golf

some of the oil is bound to get onto the bearing

it may not be as good as completely taking the whole dash out and relevant units....but it is a 1st step of helping to sort it out

the trouble with u lot is....you will happily tell someone all doom and gloom and not try and help with an easy solution to start with....
it worked for me and sorted the whole situation...SOME of the oil WILL get onto the bearing..maybe not as much as i would like but SOME will

also people on this forum find it tooooo easy to take the mickey out of someones suggestion..even the chief moderator.

it is christmas .....peace to all mankind etc etc

i see many stupid comments on this forum.. and very rarely do i comment..

and i have taken great offence to being ridiculed over the internet...think about your comments...

as u dont know me.....................u shouldnt be so personal...i could be the next michael ryan...or saddam hussein

happy xmas

Firstly, Smokie, Pologirl and I are equal. There is no chief amongst us.
Secondly, I queried with you how would the oil get to the bearing with no mickey taking whatsoever. Granted other people may have taken the mickey, and had I not got such broad shoulders, would have taken umbrage at your accusation that I had done so also.
Thirdly, there is absolutely no way any of that oil will come in contact with the bearing. The fan blades are spinning, which apart from anything else the centrafugal forces involved when the oil reaches them will disperse the oil outwards and away from the bearing. That, and of course as has already been stated, the bearing is enclosed anyway.
And lastly, your suggestion is totally absurb - that is of course unless you particularly like your car's interior to smell of WD-40 and also to later cause further problems when loads of dust start sticking to the fan blades and you have to strip the whole lot down to clean up the mess.

Just because it has worked for you, doesn't necessarily mean that it will work for others, and there is no need to throw your toys across the room either.

Second line "chief moderator".Third line "no chief amongst us"??????????????????????????

The first and second line were quoted from the post to which I was replying to.

Once again someone else thinks WD40 has lubricating properties & is good for oiling bearings.

WD40 does have its uses but as a light machine oil on bearings its about as much use as a chocolate fireguard.

Someone will be along in a minute & say WD40 is the best thing to use in locks next ;-)
focus noisy heater fan - M.M
You know WD40 is often brilliant for freeing locks and keeping them free.

I would use a little graphite powder on locks, much better
focus noisy heater fan - M.M
Without a doubt the graphite option is best but never say never with WD40 to get you out of a fix.

Like I said WD40 does have many good uses but a lubricant its not.

>>>WD40 does have many good uses but a lubricant its not

Well true I would not want to run an engine on it... and personally I mainly use gallons of the stuff every year (spray cans) as a sort of handy pressure washer in minature.

However if not lubricant what shall we call it when.... A seized fuel filler cap lock on a Discovery was preventing someone completing a journey yet a few seconds of WD40 in the lock had the key moving and the lock undone in seconds. And the funny thing.... 2 years 3 months on with nothing else ever put in the lock it is still free and smooth????

wd40 is actually a dispersant...it really doesnt "oil" anything..

it is just a term

the real stuff to use is obviously "areosol oil" or something of that nature..

to dave....."something" will get to the motor bearing....at some stage something will..

whenever is upto you to decide..but "something" will..

WD-40 is a primarily a water dispersant - but it contains oil. See the COSHH sheet below.

www.tooled-up.com/Artwork/ProdPDF/TBWDAEROSOL.pdf

So, it contains 21% by weight mineral oil, and therefore it can perform a lubrication function.

From experience it does lubricate, but often it's shortlived and once you've got the stubborn whateveritis moving you need to then use something longer lasting.

If one can get the motor out in 40 minutes then I would suggest if your DIY is up to it a proper strip down, clean, and then oil the bearings. A dab of thinish engine oil will 'stick well', and be durable enough to stay put in what is a fairly hostile environment as most blower motors are 'on' for a considerable amount of time.
A strip down also allows a proper clean up and inspection of the bushes etc.
Did this on a sticking SAAB 900 classic motor once and it ran lovely afterwards, much quieter and smoother. You are lucky if you can get it out in 40 minutes as many cars nowadays need a dash stripout which can be a day job and more.

yes MW if you take your time most things can be stripped, i find a heat gun can be very good for softening 'up one use clips ' so they dont break and as you say its a good opportunity to give everything a clean.
It is the autidata book that gives the 40 mins but obviously if its a first time then this may be longer ,some people might find it helpful to have lashings of wd40 at their disposal for any stubborn nuts or screws,but personally i dont think it will be necesary just some half decent torque bits should see you through (very cheap these days at screwfix or similar) ,its amazing what you can find on the internet when you need to find something or someone,got to go now im on my laptop and theres a storm brewing .

I would agree that WD40 is ok as a short term solution,but as suggested graphite is much superior if you can get it into the offending item. We have several padlocked gates and find by far the best lubricant for long term smothness and ease of use is that white grease spray sold by Halfords etc.
focus noisy heater fan - jc2
Best one I've used is "Comma" spray grease.
