Removing Viscous Fan trouble!? Need Help today
« on: 24 March 2011, 12:20:30 »

I'm trying to replace my water pump,
but i'm stuck at the fan and have been for 4 hours..... >:(
I'm at the point of actually destroying my car with a lump hammer because i'm so wound up.


I have my 32mm open spanner....but for the life of me i cant find a way to brace the water pump.
No matter how i do it.....just cant do it,

I'm bleeding from every knuckle...
My patience is thinner than the skin on my knuckles now...

I've tried wd40....i've tried releasing the nuts on the pulley slightly and using a spanner to brace them.


BENT THE NUTS, so now i need new ones of those too...
 Someone please help.

I need the car in 4 hours to drive to my girlfriends for her birthday...and i need it fro work on saturday..

I WILL NOT PAY a garage to do this job when it is just one nut holding me back

Yep. Spanner on at "5 past the hour", sharp whack clockwise with hammer, should release

Only way I could get mine off was to invest in a Sealey VS095 - Viscous Fan Holding Tool. It latches on to the water pump pulley & stops it turning.

Get a good BIG screwdriver jamb it between two nuts/bolts on the water pump to stop it turning(use the chassis or somthing non bendable to jamb screwdriver against) then hold the spanner on the nut push it until the fan stops moving then give the spanner a good hit clockwise.
you might need to do this a couple of times :y

Well wasnt today a fun day lol

Got it all done in the end.
But what a caper!!  :D

Eventually got the viscous undone by usung the open end of a 10mm spanner o one of the loosened pulley bolts and bracing that across the other one. Acted like the Sealey tool mentioned above.The i braced that a against a 9mm spanner held against the engine and my hand.

Then after bending said bolt i was resting against, it eventually came undone.

To top it all off then,
Was Fitting the new water pump, screwing in the bolt a bit at a time around the four of them.
None of them were anywhere near tight,
and then what do you know,
1 sheared off! right there and then under hardly any pressure.

Took the pump off again, there was enough thread hanging out of the block for me to be able to grab it with some pliers and undo it.

Anyway, had to walk to town to get new bolts from the hardware shop.
Fitted.
Tighten, replaced everything.

And now the tensioner looks like its a bit weak.
The tensioner pulley is bouncing a millimeter or 2 at idle. Still hold the belt and doesnt slip, but will need doing eventually.
That should be pretty easy though, having done this.

New coolant in.
job done.

NEVER AGAIN!! lol
I dont think my knuckles could take it

Cheers,
I have left the viscous off after reading about it on here.
On the drive today in 17 degree heat  :D ::) ;D it definitely got warmer than before, but didnt get above 95 or 96 and that was when goin uphill.
Most of the time is around 92-3 which is what it was before.

That is without the chip in mind. So i'll check it again with that in when it comes back.
As for the sound without it! Can actually hear what the engine sounds like now lol.

Although overall sound levels are quieter of course.

I may take you up on the shocker thing as i'm sure mine is a touch weak, and i've got an annoying squeel/squeak coming from the tensioner pulley (i thinik), that goes away when i rev. Will PM.
thanks

Try wd40(use the straw that comes with wd40)) first on the tensioner pully then the alternator pully.
Its best done with the engine running but watch your hand this is where the straw comes in :y

Just final update,
All temps seem to be under control by the electric fans.
I sat in a car park in the 20 degree heat we had day before yesterday and let it run with heaters off etc.
Got to bout 96 and then fans must have cut in as it dropped back down to about 93ish.
nice to hear the intercooler fan too lol.

And i can finally hear that nice 6 cylinder engine note on acceleration.
