I was wondering what temperatures people were running their cooling fans at, and what temperature thermostats they were using?
1800cc B
Im just soldering a boss into the top tank and bottom tank of my rad, to take a common M22x1.5 coolant fan switch as fitted to many 80`s 90`s cars and available in many cut in/out temperatures.
Im going to try a 92degree cut in 87 degree cut out in the top.
And a 88 degree cut in 74 degree cut out in the bottom.
My rubber bumper B has a 90 degree cut in as standard.
Im using a 88 degree thermostat.
Any thoughts or experiences would be welcome.
I`m not keen on the kenlowe style adjustable stats ugly and an inelegant solution.
( dont buy one of these look for a gas boiler spare they are the same Ranco and CHEAPER )
Im not keen on the type with a piece of metal pipe with a stat on either,

Hi Jason,
I have an 88 deg t'stat. I gave up on fan switches in hoses etc and fitted one in the car so I control when it comes on and off. Ok, you have to be careful in traffic but under normal driving I don't need it. I also had a little hole in the dash that needed filling!!

If you use a control stat from a boiler it would be best fitted at the bottom of the rad as the max temp is normally 80c.
Going off on a tangent, I have a sensor directly in the coolant on the head side of the thermostat with a digital gauge (not an NG).
I have found that the 82c stat normally opens at around 90/92c then the temperature drops in under 10 seconds with the stat closing at 82c and the cycle starting again to control the temperature.

Thanks for that, i do know with boiler stats the common Ranco types,fitted to 90% of pre electronics and thermistor sensor control ie twist and click are available as 90, and 100.They are identical construction to most sold as electric fan controllers.
I use an electrical temp gauge as well, and the 88 water stat opens approx 88 , and when i tried it in a pan on the hob with a laboratry thermometer it opened at 88, i wouldnt be surprised if the quality varies a great deal.
So many pattern parts that are supposedly OE quality are Shi*e
what do you think would be a good temp to have my rad bottom tank fan switch at, im going to try an 88 on 76 off one from a lancia.
