Disassembling viscous fan

[MattF]

Looking and sounding good then!! You've sold me, I like idea of a "big noise",
I think i'll have a go at this, I've been driveing my son's Saxo this week as he's away and while it's very nippy i cant hear the engine when its idleing so i keep thinking its cut out and it feels like your arse is on the tarmac, Much rather drive the surf, But free petrol!!! I can suffer for a week,

Being in a car is no fun. Was a passenger in the sis-in-laws car yesterday,
and that's the first time in years I've had to bend DOWN to get in a vehicle.
Give me the Surf any day. Free runabout is tempting though.

Must admit, I really was cr*pping myself when I pulled off the drive.
But, I thought Vince has been running round like this for a while, so I
should be okay. Drove like a granny to the first call. Popped bonnet,
checked everrything was still where it should be. Everything okay. Then
spent rest of afternoon driving like Mansell. Must admit, though, I did
pop the bonnet after coming out of every place I stopped, just to make
sure everything was still in place and that it wasn't wobbling on the mount
like John's. Being 2.4 owners, we're used to the smell of fear every time
we leave the drive in the Surf. Can't say for definite, due to the viscous
fan being a bit louder and the fact that my front exhaust pipe sounds like a
wet fart at the moment, , but I can't say as I've heard the electric fan
kick in today, even in this heat. So, I'm chuffed enough. Oh, by the way,
did I mention that my fan's now BRIGHT BLUE.

I've done it and the truck seems to 'breathe in' better.

Is that the excuse you used to convince your wife that it really did
need doing?

[BUSHWHACKER]

To be honest, I don't think she's noticed, but then I've got a roaring fan, roaring air intake, rumbling mud tyres, a slight whistling from the roof mounted lights and no under bonnet sound insulation!


She's got her own car anyway.

If you like a roar as you accelerate, pull the rubber elbow off the intake trunking that comes from behind the passenger headlight, and turn it around so it faces the bulkhead (you can remove it completly if you like) and you'll get an induction roar. I've done it and the truck seems to 'breathe in' better.

Is there any risk involved to the turbo with it sucking hot air in from the engine as opposed to sucking cooler air in from the front of the truck???

There seem to be quite a few people who have the induction filters
fitted in place of the standard air filter, and that part of the engine
bay would be even hotter. Might be a tad less ooomph, but I don't
think anyone has had any directly related problems turbo wise.

Just like to say, as well, thanks Vince for the encouragement and
advice on this fan project.

[BUSHWHACKER]

I have bonnet vents, so hot air from the engine bay is blown out through them (as long as I'm moving of course) so I don't see it makes any difference to the intake temp. I'll be fitting my intercooler soon so the intake to the engine will be cooler anyway.

[hawkwind]

Think i`ll give this one a miss then as i was doing the mod when a neighbour came along for a chat (used to be a mechanic) and he advised against doing this as he said the turbo gets hot enough running normally as it is so i dont want to be sucking in more hot air .
He did go into all of the technical details why but it went straight over the head.

[MattF]

Bugger. Ian's posts about his bonnet scoops have disappeared.
Just to mention again on that one Ian, If you really want L.E.D
overdose, I have some 12V L.E.D fans which might fit your
vents. 80mm and 120mm if I remember correctly. (As you
can probably guess, I'm a habitual hoarder).

Well, just to join the list of people who have been modding/upgrading
whilst the forum has been offline, , ended up dropping the rad off
last week as the rad flush highlighted a few leaks. Now has a beefier
three core rad on, (original rad recored), and practically all of the water
hoses have been replaced. Apart from the little dog leg pipe on the turbo
cooling pipe and the two big rad hoses, every other hose has been
replaceable with standard straight hose. (Obviously, slightly larger curves,
but are clear of anything rotating). Old perished hoses are a devil to get
off rusted/scaled pipe, and those spring clips are evil. Did also
leave the hoses that are directly connected to the matrix's, as they are
tightly curved moulded ones at the front.

stop right there

i hope no did what i did while the forum was down (slitting my rists((fitted a kenlowe fan) bad expensive move, it nearly cost me 8k as i nearly went out and bought a volve V70, any way kenlowe fans and surfs( well my surf) dont mix i hooked up caravan on sunday hoping all was cool, bugger, the first big hill and into the red she went.

back to basics im now after a good second hand viscous fan, thats what mr toyota fitted as oe so it must be the best.
will keep you up to speed

Hi Matt, It's nice to be back! There's a few post's missing! I reccon they crashed the site deliberatly to get rid of me and my useless bling
Thanks for the offer of the fans, I know which ones you mean, my son has em in his tower, Dont think they work with my vents though as they will be screwed on the under side of em and will only be visible from inside the eng compartment, I'm just gonna plant a few inside the vents, Spent most of the weekend takeing the vents apart by drilling out the spot welds so i could strip the paint ready for plateing, Local guy is doing em for £35the pair in polished nickle, he says its better than chrome so we'll see! I've painted the base part and baffels in blue not that i'm copying you, its the only colour i had, plus it will go with the led's,
Yeah those hose clips are cr@p i replaced the top hose ones with good old jubilee's and intend to replace the others as and when!
You did'nt sign up on the Aus site then, It's very good, Dont feel quite as at home there as i do on here though but well worth signing on, There's no mods
forum at least not that i could find, i was gonna post loads of led pics and
pi$$ em all off, they cant get me from the other side of the world Ian

Sorry to hear that John, What happened????? You'd think a kenlow would be much better than the viscous, It's only the price of em that put's me off,

Obviously not going well, then. What caused it? Switch on temp too
high, or fan just not able to cope? Ironically, on electric fans, nipped for a
run to a garage down the road earlier, to check for leaks on the coolant
pipes, (found a slight one on the return hose from the bottom of the rad,
so the hermatite's going on later), and the mechanic noticed the locked
viscous fan. He mentioned that most people, when upgrading the cooling,
removed the viscous fan and used an electric one. I told him I don't trust
electric's, which was why I'd locked the mechanical one. Obviously, it
appears I may not have been far wrong.

If it's of any interest John, another thing I've been doing whilst the site was
offline was browsing a lot of the Australian and American forums. Apparently,
the Ford Taurus has a two speed electric fan that is a fairly straight fit, (minor
mods required), for some Toyota rads. Might be worthwhile checking if the
same fan is used in a U.K model, and having a scr*pyard delve.

I WASTED £200 AND A LOT OF TIME
today i spent 35 minutes on my mobile talking to Kenlowe about it
they had 2 answers
1. spend another £140 on a supplementry blower fan on the front of the rad
2. get the rad flow tested.


i spoke to a mate tonight at toyota whos going to find me a viscous fan to lend and he suggested a flow test as well.

so now its off to a specialist rad bloke in llanrwst soon and try a good working viscous,

anyone know if it could be my water pump and whats involved in changing it, just a thought as they are £38 from milners
anythoughts guys as im getting desparate
john

[BUSHWHACKER]

To change the water pump you have to go through the same proceedure as changing the timing belt!!!!
