Radiator fan thermo switch

[RXFORD]

I'm needing a thermo switch that I can fit into an Ali radiator hose adaptor/joiner.

I can weld in a threaded boss to suit no problem so thread doesn't matter, but being that its not earthing on head/rad, I need recommendations on a good switch that I'm guessing will be 2 wire. Doesn't need to be a fancy adjustable one or dual temp, just looking to make the current setup, which is a manual dash switch, more user freindly.

 

Cheers

Factory in a bunch of small Holdens, pick a part for a plug.

Thanks, sorry I should have been a bit more informative. 

I was hoping to here what other have used without failure as there seems to be a big price difference between some listed through supercheap/repco etc, and Davies Craig / Spal switches that are $100 upwards.

Don't want to buy some cheap thing and have it fail, but it others have used them successfully then I'l take the punt.

Have personally used a Fuelmiser switch (oex is just the supplier) in the past, as far as I know it's still working fine now but I don't own the car anymore.

I only linked that specific one as it's down from $120.

@RXFORD,

the Tridon ones are pretty good.

ive only ever had one fail because it was as least 20 years old and it didnt fail, it just changed resistance so the fan came on to soon. 

their range is pretty good to so you can find something to suit without to much drama.

Tridon tfs133 m16x1.5  is one of my goto 90 on 85 off and 2 wires so crimp to what ever suits 

Or tfs106 95 on 90 off m14x1.5 2 blade terminals

this style of thermostat is an easy fix……cheap, you can sikaflex the sensor to the top tank, or even insulation tape it to the top hose….. I normally weld a tube into the hot tank of the radiator….. it’s adjustable and if you want it can be used as a digital temp gauge….
