Took My 1500 fan off My alternator to replace it with a doghouse fan found nearly a round hole.... YIKES


just lucky I guess..

wouldn't have been long before it started to spin depending on the tightness of the nut..

Hey Lee
You do say YIKES alot...lol

yeah AND OVERUSE UPPER CASE LIKE NO TOMORRROOOOOWW 😂

drugs are bad!

shokwave2 ·

Hey Lee, what type of paint did you use for your fan shroud? Heat resistant or just normal spray paint?

Camo ·

Lee,

just another tip, I think the fan goes in the other way around 😂😂😂😂😂 😉

Arrhh! its too yellow! 😬

"puts on welding mask"

Hi Lee

Make sure you have enough shims under it otherwise the nut will bottom out.

I think the paint fumes are affecting your judgement, what wrong with black?

HI Kev

I didn't really notice... lol

I normally use heat proof VHT paint .. which isn't very shiney
I then use clear VHT over the top of it...

this time I have used killrust EPOXY spray paint...
I just sanded down the fan shroud, but the tinware over the heads etc I have taken all the paint off...
this paint then needs no undercoat its self primiing..

It has no heat rating but its an excellent paint... very glossy..
takes about 6 hours to dry...
I'm hoping it won't peel off... lol..

cheers

Mr Henry ford liked black... lol I like Yellow now... lol

Steve...
I had to take My alternator 30klms to get My Son to take the old fan off the alternator and install the new one..
BUT
I forgot to take the heavy waved spring washer with Me...
the old fan did NOT have that washer but did have shims..

this fan had 2 or 3 shims on it so WE left them there..
rattle gunned the nut on with locktite...

so, I don't think it will come loose..
but will it be OK without that BIG waved washer??

I thought the shims were just for aligning the fan??

LEE

HappyDaze ·

Make sure the fan has NO PAINT on it........otherwise the flats on the centre hole may 'flog out'.

cb john ·

Lee, you need to arrange shims the way, that you have 2.0 mm gap between the fan and the fan cover...the lock washer is necessary..

😂it seems, that there is no workshop manual in your posession..😂

ragged ·

Yes thats all fine, but what colour is the nut? Red would have to be the go!

Cheers Dave🤪

1303Steve ·

Hi Lee

That fan nut only needs to be tightened to 40-47 ft.lb, don't know why you would need a rattle gun for that. The paint on the fan could also affect the balance.

My Son thought it was a new fan... nice flat black
and oddly enough I left it that way...

Hi Steve

My Son has had problems taking these nuts off... and I searched at Home but I couldn't find the 36mm socket...
My Son assures Me I have one... and he also has one but couldn't find it.. so We went to His work workshop and used their socket and rattle gun to get the old fan off.. and naturally used it to put the new fan back on.. He said he snapped a shaft off once using a rattle gun on these so He didn't use much pressure but also used locktite..
It had NO waved heavy washer on it and I had forgotten to take another one with a nice yellow nut.. lol
so its got a black nut and the shims that were under the old nut... I know its not going to come loose.. but do you think there is enough pressure there to stop any problems with the fan moving?
I have heard of people actually welding the nut on...??

cheers

LEE

pic of the ones I left at home... notice very thin coating of paint on the washer..

the Nut should have been yellow but as I left it at home
[30 klms away] I reused the flat black one... lol

LEE

HappyDaze ·

That's a worry, Lee. Can't remember EVER leaving my nuts at home.....but I'm sure I wouldn't have got 30km before realising.🙅

helbus ·

I would worry if I had a black nut, however I would be very concerned if I had a yellow nut.

sungold yellow yeah? I recently used this for some stuff and it takes weeks to fully cure, seems to be heat proof.

don't paint your nuts or washers 🤪 or the surface they bolt to for the matter of fact.

I learned last time from that mistake. They come loose every time guaranteed, extra espesially for epoxy paint!

Klaus ·

next time u paint your nuts use an elastic band around them tight so there is good definition between them and the shaft , a little baby oil on the shaft stops the paint sticking and reduces friction👍

68AutoBug ·

I usually take all paint off flat washers and nuts and surfaces before tightening..

then I paint them...
I let the paint run into the threads and have never had one come off...

I used to have some loctite called after lock and You put it on after the nut... it ran into the thread and locked it...

LEE

kombibob ·

wow what a thread!!!

D-train ·

kombibob wrote:wow what a thread!!!
You said it bob, that's a really good idea klaus, some baby oil will also help lube the shaft as well, so when its inserted an screwed in hard, you shouldnt get too much friction on it an break ur shaft if it's tight.

HappyDaze ·

Some good advice here. One good lesson to be learned, though.......NEVER leave home without your NUTS!

HappyDaze wrote:Some good advice here. One good lesson to be learned, though.......NEVER leave home without your NUTS!
would You take the black one or the yellow one??
or both..!!

Lee

I believe many non mechanic people forget that when tightening a bolt or nut etc that having the thread lubricated the bolt or nut will go on tighter do to less friction...

especially if using a rattle gun or torque wrench...

LEE

vlad01 ·

The black ones are no good as they have taken a bad beating and the yellow ones are Chinese.

D-train ·

Lee, do u have a special lube u use for less friction? Do u also find if u don't use any, does it make it harder to screw it in?

Klaus ·

well see mr d-train i was talking to an older mechanic today describing the problem with lee's rear oriface flogging out and he highley recommended lube but a waterbased one as this would ensure there was no galling on nuts or shaft , he also mentioned that whenever a vw related oriface was flogged out or looked sus they would have to contact a gentlemn at vw by the name of Colin ..ahh what was his last name something polish or eastern european ??? Oskapi thats it , he said weird guy only little and would introduce himself really quickly saying his first and surname together, the previous guy was a bit of a dick and was huge and the guys didnt like the thought of his huge hands near the oriface problem, Some of you older guys might remember him said he was pretty busy in surrey hills and oxford st mechanics , oh i found out the proper name of the elastic band thing to its a rooster ring he said best way to fit it so there was definition was to use someone with clean hands to hold the offending nut/shaft and get it as close to the nut/shaft meeting surface , then lubricate liberally on the parts not wanting to be painted ..hope this lets u know that your not the only one to have a flogged out hole

kombibob ·

lee i think you should go with two blue nuts a red shaft and paint the inside of the fan hole pink.
would look great.

vlad01 ·

D-train wrote:Lee, do u have a special lube u use for less friction? Do u also find if u don't use any, does it make it harder to screw it in?
yeah it can feel a bit dry when screwing in if you don't lube the shaft first, also good idea to get your fingers inside and lube up the hole before you insert the shaft.

kombibob ·

also lee i find if the hole is flogged out turn it around and put the shaft in from the rear
but make sure you use the lube or you will flog out the rear also.
hope this helps

Very good information, finger the hole with lube as well.. It should penetrate easily then, an wont be tight or hard to screw.

haha, then that fan will blow nicely 😂 👍

Yes it will blow all over the engine then.

and dont forget safety glasses and a hat as it may blow something in your eyes or hair

kombibob ·

or your mouth!
you wouldn't want it to blow in ya mouth.

I wax my nuts, i find it a cleaner surface... lube is good as well, but not on your nuts, although when waxed they are very smooth...

It's a good thing he didn't have blue nuts

Try shaving the nuts for a smoother nstallation.
