Fan Thermostat?
I'm fitting a radiator and fan from a Nissan Micra. I was going to use a fiesta thermostat housing for the fan switch, but the wopping great
plug on top won't fit under my nosecone.
Can anybody suggest an alternative method for controlling the operation of the fan?
Appreciate any help.
This is my first "new topic", so a little bit of history being made here today!

There are several different sensors that can be fitted inline in the radiator hose. Burton Power do several different ones.
Some of them are adjustable so you can change the temprature that the fan kicks in. They are about £30 - 50. Have seen them somewhere else, but i cant
remember where now 
Hope this helps

The sierra 1.8 td has the fan switch in the radiator hose, I'm looking into the suitability myself
If you can keep you head, whilst all others around you are losing theirs, you are not fully aware of the situation

Thanks for that. Sounds promising. I'll have to look into it.
I was starting to worry I would have to drop my engine!!!!
If these switches are in line in the radiator hose, does anyone have any thoughts on the effectiveness of drilling & threading a bit of pipe and
fitting it inline with the fiesta switch screwed into it?

Shouldnt be a problem if you can sort the right thread mate.
P.s Demon Thieves do the adjustable inline fan switch. I have got one on my car as it happens.......
Dont just build it.....make it!

I gave up trying to find a way to mount a stat reliably and just wired the fan to be on all the time.
If the micra rad is a bit marginal, and your engine is big, and the bonnet is cramped, it might not be a bad thing. So for me, running a cologne V6,
on all the time inst such a bad approach.

FWIW, the polo radiators have the thermostat built into the radiator. Makes it all very simple really...
assuming it works that is...

Fan Switch
The micra one has one built in - it is on the opposit side to the filler (?) cap. Supply power to the stat. it switches at 96deg. fan comes on. Our
temperature stat is in the engine block of the fireblade engine, not in the radiator.

There are some thermostats where they use a wire which fits in the top rad hose-just take the hose off-feed wire in then use some sealant and clamp it
back down.
HTH.

Sorry to hijack the thread but can someone recommend a good place to get stainless/copper pipe and a good selection of cheap radiator hoses in
different diameters and bends etc?

Scrap yard? Plenty of combinations of bends and lengths on cars there  just have to make sure the hose is ok and the different lengths wont
matter if you are using stainless or copper to join them up.

Heh, just been to scrappy. We have all the hoses we need for a test run, I was really just wondering about a good place to get new stuff for the
proper installation, mainly the metal unions and big jubs.

Hellfire's right- there's one built into the Micra rad.

Joel,
Is that the water thermostat or the fan switch?
Also, do you you know what diameter the in/out pipes are?
Thanks,
James

Davem
When you say the whopping great plug, what does it look like? there are two types of fan stat that goes in to the fiesta a small brass on with spade
connectors on top or a brass one with a largish plastic thing on top, if you have the bigger one then get a small one from a local auto suppliers.
Does this make sense?

James!
Its the fan switch... nearly forgot the difference! Of course the thermostat cant really be in the radiator unless the water constantly goes thru
it.
The polo came with 32mm pipes on it, though 34mm sierra ones still need a wiggle to get them on. Im using a selection of pipes, with 32mm copper tubes
to join them top and bottom. Gonna put blobs of weld to make the 34mm end fit better!

Mild steel is fine - jag used it on the v12 - takes over 15 years to rust thro.
got to a scrappy and get lotsa odd bits of hose....they wont charge you much. if you see one you really want to buy new, at least you know the model
it came from - if you write it on the hose. However, when you find out that things like sierra bottom hoses cost 20 quid, you might want to use second
hand ones....

Try this mob in Stoke and Nottingham
www.oakbray.co.uk
If its rubber or plastic and its got a hole through the middle they'll have it and they do mail order I think
I got some flexi hoses for mine for a very good price so didn't use any fixed bends at all.

Well loads of options then!
I'll have to get my radiator down and see if I can find a fan switch.
MarkP for info I have the big plastic plug so failing above I'll have a look round for a smaller version.
THANKS EVERYONE

Just change the big plastic type for the smaller one, simple really. they both fit.
simple to do and cost about £2

fan thermostat
Once had problems with coolant temperature getting very high when towing a caravan uphill in hot weather using a turbo diesel with the intercooler in
front of the rad, tried a bottle of Water Wetter from Demon thieves, dropped the coolant temperature by approx 20 degrees. may be worth a try if your
cooling system is a bit marginal. cheaper than a head gasket Rusty

Duurrrrrrrrr!
Got my radiator down, and there it is, staring me in the face.
Wires going from my fan to the radiator, connected to a fan switch/stat.
Thinking back, I wondered what that wire was when I bought it!
Got there in the end, but I think it's worth repeating:
THE NISSAN MICRA RADIATOR IS DEFINITELY FITTED WITH A FAN STAT
I may have this engraved on my forehead.
