Toyota DNA + Ford DNA = Red headed step child??
I mean...good luck. Sounds like an interesting project.
Can't say there's much that I think an AU Ford Falcon motor could improve on a 1UZ, but an interesting medical experiment none the less |

Man i hate it when electric fans kick in. If you do it, use a variable controller or something to keep it nice at least. |

yeh righto, this place is like walking into a morgue. so much negativity and nay-saying.
i was going to post an update with pics, considering i've nearly knocked this over in an afternoon - just some minor wiring left to do. but doesn't seem like anyone is remotely interested anyway, so if anyone is curious about doing a similar mod in the future, feel free to PM me.
and cihan, a variable controller with digital readout is being used. just need to work out the best way to tap in for a reading. there is a brass fitting that can go into the bottom of the radiator, but i need to find out what removing that is going to do. anyone know of any blanks places in the water system? otherwise it will be a temp probe under the radiator hose. |

As to the pump not running you can just use a shorter belt . |

i dont need to worry about that, ls400 does not have the hydraulic driven system. it is a basic viscous coupling. belt runs as per normal, but only difference is it's no longer turning a dirty great fan that weighs about 8-10kg.
and again, if anyone knows of a good place to tap a sensor in. i'm thinking i can also use the ecu temp sensor in the top of the water pump.....? that will send a decreasing voltage signal as temp increases with resistance? |

you could buy one of those inline radiator hose 'probe' joiners. Basically you cut a radiator hose, and this part goes in between them, secured by hose clamps on both sides. It has threaded and plugged holse to take a number of sensors.
SOmething like this (they come in various sizes)

I haven't read anything here since the first post, but you are a fool if you decide to remove the hydro fan and replace it with AU thermo's.
As good as AU thermos are (I use them on pretty much every engine conversion I do), the hydrofan will sh!t on them from a great height.
Just source the required parts and replace it.
You'll be lucky to get change from $300-$400 for a thermo fan conversion. |

Andrew like I was you are confused , he has a LS400 not a Celsior therefore he does not have the hydraulic system , just an engine driven fan with a viscous type clutch , so he is probably better off with thermo's !! |

Ahh, I saw the word 'hydraulic' in the first sentence and missed the word 'clutch'
I still think you are crazy to change to thermo's, mainly for the $$ value this time.
A second hand viscous clutch from a 1JZGTE would be like $50, versus $250ish to convert to thermo's.
30 mins work compared to about 4-6hrs.
Unbolt old clutch, unbolt fan from clutch, bolt new clutch to fan, bolt clutch to car. beer.
vs
unbolt old clutch, remove everything to get to radiator, drain coolant, unbolt everything attached to radiator, remove radiator, bolt pulley back on with washers as spacers, put radiator on bench, remove shroud, put AU shroud on radiator, trim where necessary, fab up something to bolt AU shroud to radiator, fit radiator back in car, remove bolt on top of thermostat housing, drill/tap hole for thermofan switch sensor, fit sensor, find IG+12V wire, fit relay, fit fuse, wire up thermos to battery/trigger/IG/earth, fill with coolant, test, hope, win. beer.
Seems like a no brainer.
Unless you want the challenge, in which case, go for your life. |

You have to understand Matt's point of view, Andrew. Karl Mohr was lost pages ago and even Newton is going down.

all done and dusted guys.
very pleased with the result.
ended up using a joiner as pictured above, but in anodized black, so not so ricey.
wiring took the most time, mainly because i wanted it all hidden, but also because of the massive intial draw on the thermos i had to use some pretty serious hardware. not helped by the fact that the control box of the digital controller could only withstand 20Amps, so i had to use it as a trigger only for a 40Amp relay and wire from there. tested with the A/C running, stereo up, and HID's on, the thermo's kicking in didn't phase the alternator at all. 100amp alternator is up to the job it seems. |

baptism of fire, drove it to work today, 70km trip 90% highway, 10% stop start traffic. The car seemed to sit around 93degrees going up to 97ish at stages.
I had the controller setup low for safety sake, switching the fans on at 98 degrees and cooling back to 90.
my question i guess now is what is the ideal operating temp? if i set the fans to come on at say 105, cooling back to 93?? any other opinions?
(the way the controller works is once a set temp is hit, it cools back 8 degrees from that point) |

I've always had my thermo's come on at 95 and off at 90.
The car should sit around 85-88 cruising on the open road.
IMO anything over 100 is getting too hot |

ok thanks for that.
some research from coolant companies has said that most engines are being designed for an ideal operating temp of 215F, so about 101 degrees. argument being that it allows the engine to get hot enough to boil any water from the oil, but that the oils are good enough quality to withstand the heat.
so i'm going to set it for 102 and cool it back to 94. see how it behaves.
also did a coolant change, very quickly - and my christ - i felt ashamed for my car, the previous owner had clearly neglected that area of servicing. my old man walked past and saw the buckets of old water and said 'oh, are you changing the oil?' thats how dark and dirty the water was! just did a quick 50/50 mix using off the shelf stuff as the car will need the water pump done in the next couple of months. |

If the ideal temp was 101degC then the thermostat would be set at about 98degC.
Generally the coolant (while cruising) will sit about 3-5degC above the thermostat opening temperature, which is 82degC.
You should also only use Toyota Red for the coolant.
50/50 mix with distilled water. |

Prices on thermo conversions seem a bit expensive on this thread.
Just converted my mates 1j z20 soarer to au thermos,
The fans cost $60 from the wreakers (if you must have brand new then its only $115) and a controller cost $15
Not sure where these figures of $250+ are comming from.
Au thermos sound like crap and put a heap of load of the alternator, but they do a good job, Better then stock?? doubt it, but if they do the job and cheaper to replace and easyer then stock, then do it.
Too many haters on this forum. And for people who think people other manfacturers parts on a toyota is wrong, Do you seriously think Toyota makes all the parts on these cars? Of corse not haha. |

yeah, dave, all my costs basically came from the controller and associated wiring.
costs were basically:
au fans $100 (cheapest i could find new on ebay was $170 del)
digital controller $160
thermo sensor housing $30
40 amp glass fuse holder (had to use a stereo one) $20
and then about 40 bucks for a 40amp relay, 50amp wiring and all the connectors and terminals.
so i admit, it wasn't cheap, and could definitely be done cheaper but i have a nasty affliction with my car, where i can't sleep properly if i know something has been done on the cheap.
that being said, coolant was just a temporary. i will definitely be getting genuine coolant put in as timing belt and water pump is being done at toyota.
in terms of noise, to be honest, they cannot be heard from in the cabin - i kept putting my window down at the lights to check if they were working or not and even then had a hard time. and compared to my clutch fan seized on and running flat out, they are 10 times quieter!
also the throttle response is noticeably better, admittedly i had a few days of the clutch fan seized on which was absoloutley murdering performance, but now it feels much nicer again.
just hurts a bit, if it wasn't broken there is no way i would have fixed/replaced it. that money could have got me my new exhaust and i would MUCH prefer that sound. so yeah.....cars....why must we love them so! |

$160 for a fan controller! :S Wowsa :S bit prices for what is $1 worth of electronic parts.
The controller kits I get are $15 and come with all the required sensors relays and fuses. |

well where were you at the start of this thread with that info 
i investigated plenty of options from as expensive as the spal units at over 250 bucks, down to the jaycar sensor kit for 24, to the more mechanical methods of tridon thermo switches, and even pick-a-part stuff like magna switches.
spal was too much, and didnt even give you any display info.
davies craig stuff was given the black ball by a mate who has been through two failures, also pretty ancient technology and looks pretty messy in the engine bay.
tridon switch would have been good, but i didn't know of anywhere other than the factory locations (radiator ortop of thermostat housing) to tap one in, and i couldnt get confirmation of what was safe to replace without upsetting something else.
in the end, this was the most reliable and confident way for me to do it. but its a nifty little gadget - in cabin display, monitors the temp live and obviously can adjust the settings. tell you what though, i had heaaaps of fun running the wiring through the grommet in the firewall and down through the dash!
also monitors voltage and gives a warning if the alternator is overcharging or undercharging, which is good peace of mind with the hit to the elctrical system the thermos give when they come on. |

Because thats what genuine Bosch ones cost (RRP is about $250)
The cheap Chinese imported ones are the ones you are speaking of.
(unless they've DRASTICALLY been reduced in price in the last couple of years) |
