Go to your local motor factors, they should have a listing for fan switches giving the fan on an off temperatures

My car was running at 90 to 95 and went to 100 if stopped for a minute. I have put in a 82 deg stat and was wondering what temp range on/off switch I
would use that would operate with the 82 deg stat. Burton have a 95/90 or a 95/86. or is there another one that would suit better. I am using a vw
expansion bottle in the system.

I have run X-Flows in Escorts and Caterhams, all had 74 degrees stats which was the standard Ford fitment. Sold my last spare on E-Bay, they went
crazy for it. Was told they are no longer available. The engines ran at a rock solid 78 degrees on an accurate gauge. The Escorts always ran the
standard viscous fans so no fan switch, on the Caterham I ran 86 degree switches along with a manual override.

With the engines at these low temperatures I'd be concerned that the oil isn't getting hot enough to boil off water that condensates
inside the crankcase.

Well I ran the engines for probably 20 years and never saw any evidence of crankcase corrosion or mayonnaise in the rocker cover.
With a water temp of 78 degrees the oil temp was a rock solid 80 degrees in normal running but would get over 100 degress when pressing on hard or
standing in traffic.
As a comparison using the exact same gauges and sensors my Zetec (fitted with an 88 degree stat) shows a water temp of 88 degrees with an oil temp of
70 degrees normally which never goes above 90 degrees.
Neither engine was fitted with an oil cooler.
I would think that Ford know a thing or 2 about choosing the correct stat.

I hate when wrong info gets put on the net as fact.
The standard thermostat for temperate climates in all Fords for the 1960s and 1970s was 82c
88c was the hot heater option for cold climates and later became standard.
74c was an option listed by most UK manufacturers for tropical climates and competition use.

100c is well below boiling but with an 82c stat you can run a fan switch that cut in at 90c and out at 87c. or so.
What thread is your fan switch fitting?

Not wrong info. That is the absolute facts I posted. Having worked on Escorts from new I know what Ford fitted.

Thanks for the information. I am using a fiesta thermostat housing which is 22x1.5 so will try and find one that is on at 90 and off at 87 and try
that.
