It should sit on the bar with the arrow next to it, in the halfway position. Mine never deviates from that unless I'm giving it a thrashing.

my 5me used to sit one below the bar, unti i was either:
Stuck in traffic
Cruising 110 on highway
then it would go up to the bar, but never over.

I've given up on the clutch fan and today I am going around the auto shops for an AU Falcon Thermo fan and the fugly box which sits on the side of the radiator as I got nowhere to tap a sensor nor want to put holes in the radiator tanks.
I'll get photos of it when I do it tomorrow, if I can source cheap Thermo Fans. The Ford dealer wants $340  for them 
Cheers.

I bought mine of Ebay. They were Brand New EL Ford Thermo's and cost $230 delivered.
I think they are slightly different than AU, but not sure. Anyway, they'll fit fine with mine.
I'd get the rest of the system checked properly before lashing out on such a purchase though..

It's too late, I went the local dealer... Oh well... I'll head up your way Allan this arvo and we can do a "Sting Operation" on your closest dealership on a mission - "Sting Op Cheap AU Fans"

teh 5me supra sits on half, sometimes one bar below. thats a reconditioned radiator too.
teh 7mgte supra is the same, with a recond. radiator. it overheated on the way home which was pretty funny- but i think it was due to no coolant in the top tank
just out of curiosity, what does it mean if the radiator is blowing bubbles into the overflow tank after driving?

You mean after you switch off the car...? Or when the car is just idling...?
Either way I think it means its running hot and coolant is boiling off. I hope I'm wrong.

its when i switch the car off. the radiator and associated accessories aren't overly hot, and the temperature gauge suggests its running fine. theres no coolant in the oil and the coolant is a healthy colour. exhaust blows no smoke...
im thinking theres a coolant leak from a hose somewhere. if its a headgasket ill go spastic, it's already done 2 and now has a HKS metal one. ive got to get the head torque checked i think...
michael- there was no coolant in the overflow bottle which we thought was a bit odd. we topped that up and forgot about the radiator. fairly stupid aye.  
but since the trip is hasn't got hot at all... which is good.

Change your radiator cap and see how it goes, it seems that the spring may be loose or gone...
But why? Aren't you going over to the 7M

yeah i think i will change the radiator cap, its getting serviced soon...
this is on buffy, the red supra, with the 7m.
however the white supra has a fully recond radiator etc and its all fairly new so it should be peachy in the white one anyway

I called around some ford wreckers - got my au falcon thermos brand new for $250 with a 1 year warantee (which I promptly voided by cutting the shit outta the shroud and messing with the wiring).
Oh, and AU thermos are one of the main reasons I hate PNPL - they wanted $250 for AU falcon thermos with a fubar shroud

The guy I got my new EL ones (BNIB Genuine Ford) are back on ebay (maxcashflow is the seller - I think that is the correct spelling) and there is some AU XR8 ones that are 115 at the moment.
Looking at the pics of the AU and EL ones, it appears that the positioning of the fans is the only difference

It's called heat-soak and it's quite normal. When you switch the engine off there's still a huge amount of heat stored in that big cast-iron block, and with the coolant no longer circulating the temperature can rise above boiling point. The radiator cap lets the steam out via the overflow bottle, hence the bubbles.
My 2JZ used to do this all the time until I wired up my thermo fans to constant power, ie if the coolant is hot the fans will come on even if the ignition is off. No more bubbling.

did the fans ever run enough to drain the battery so you couldnt start the car again?

I've had my thermos wired up like this for nearly two years and I've never had a flat battery. In warmer weather the fans can stay on for half an hour after I shut off the engine, but it doesn't seem to be a problem.

It's just a normal "heavy duty" battery, nothing special about it. My fans aren't especially big though (they're MA70 aircon fans) so they probably don't draw that much current.
Draven: there is actually quite a lot of coolant flow thanks to thermal currents. Proof of this is the way the fans cycle on and off every couple of minutes after the engine is hot; they cool the radiator and switch off, then after 30 seconds or so more hot coolant has flowed into the radiator so they switch on for a couple of minutes, then off for another 30 seconds, and so on about a dozen times over.
Also, if you watch the temperature gauge you can see what a difference the fans are making - the temp only climbs a couple of bars above normal, but with no fans I've seen it go all the way to the top and start flashing. That's indicating coolant temperature just out of the cylinder head, not in the radiator.

Done the conversion... I would like to say a HUGE "Thank You" to Allan for helping me fix & wire up the Thermos to the car... Also I can't forget Yian and his LOW Supra as he went with Allan & I to pick up the Fans from Ford...
I'll post the Pics as soon as upload them on the Net.

... Allan did most of the work and I stood back as I wasn't confident in doing it all on my own and didn't want to screw up a perfectly good radiator and scratch/damage the MA61 in anyway. PM/Message Allan as he would be happy to help as he did a fantastic job and both of us are happy with the job.
