Hi I'm considering to soon put some EF thermofans in my EA falcon and want it to be fully automatic, so need a thermo switch.

I don't have alot of money and electrical thermoswitches are pretty expensive, so I was wondering if anyone knows of any other cars I can get a plain thermo switch off at the wreckers. Preferrably I am after one off a car that is a dual-stage sensor so either none, one or both fans can be running.

Any ideas on which cars might have one of these cheeky buggers in it?

Thanks

I bought switch from Ford that screws into bang on thermostate housing via a relay.The switch earthed triggered realy to to switch on...

Or you can purchase the Davis Craig fan switch.You need to install thermostate through radiator hose and radiator outlet pipe... Around $80.00 @ supercheap etc..

Ive had a the Davies craig Thermo switch in mine for years with no real hassles.
The Ford switch would be alot neater but.
EB Can you give us some details on the Ford one?
Was it just to suit the V8?

i have one out of a telstar... i know that i am a cooling freak, but its prolly gets a little hot before the fans come on. the gauge hits the M C [ NORMAL ] H before the fans come on, and they turn off just on the N. If i have the A/C on its constantly cool. If i am sitting in traffic i just wack on the A/C and its all good.

I would like to get one thats a little cooler. Also you need to make sure that your thermostat opens up before the switch turns the fans on. I only have a 1 stage switch so both fans come on at once, and both also turn on with the A/C.

The one in the V8 is operated by Haltech..Ecu controlled...

The XR6 is fitted on thermostate housing.I'm not sure what model this came from I got it through Fairlford in Sydney www.fairfordspares.com.au Gow St Padstow 02]9709 4777...
I notice some are fitted on lower radiator / hoce and some on top of radiator so it depends where is was fitted on original car to what temp settings are.Fans can be set up seperately on there own relay etc so if one fails atleast the other will still work hopefully...

Or better yet BPT do a beautiful proffessional wiring loom.
Go have a look on their website.
Looms only $70-80.

I have an adjustable temp switch hooked up to a relay. Soon to be switched by the ECU.

I don't think the adjustable switches are that much. If you want a fixed rate, just walk into Repco and ask for one of the temp you want. 93 or 94 degrees is probably best, just after the thermostat opens.

I have one of the Davies Craig ones from Super Cheap Auto, it came complete with all wiring, relay, adjustable switch, crimp terminals etc for $69. Follow the instructions and you cant go wrong, its all supplied. As for a cheaper option I know a lot of people just have a on/off switch but how annoying would that be? "Oooh, look hun, the temperature is rising, quick flick on the fans would ya!" Haha.

I'm guessing the Davies Craig and Repco ones are only single stage switches correct?

Another thing I need to know, I know I have to set the thermo switch higher then the thermostat, but what do you recommend I do, get say a 95C switch and leave the standard thermostat in there.... or put a 92C switch in and put a lower rating thermostat.

Thanks

I'd be leaving the standard thermostat in there, I haven't had any issues with it.
