Djape ,

what do you mean on/off variations?

i can get you a thermostat and/or fan switch of any sort.

for head mounted application a thermostat from yugo/zastava is a bolt on fit, also available from 68-92 (or 96?)

At what temperature does it go on and at what temp off ?

[djape1977]

there's diferent startng temperatures. for example, it starts at 72 and turns off at 68, or on at 86/ off at 78 etc..

will post details when i check what's available at local stores

Djape, 

Any luck ?

sure, but i forgot to post answer  

there's about a dozen diferent on/off temperatures available ranging from 68/76 to 98/104 and peretty much everything in between. prices also range from about 2,5e to 10e. experience has tought me to steer clear from cheapest ones. 5-10e range usually works flawlessly. many diferent makes available also.
interesting fact is that fan swithches for

FIAT - 125, 127, 128, 131, 132, argenta, ritmo, regata, panda
LANCIA - pretty much all models
VOLKSWAGEN - golf mk1 and mk2, polo mk1 and mk2, passat mk1 and mk2
AUDI - 80 mk1, mk2, mk3
ZASTAVA/YUGO - all models

are interchangable, with same thread, so they're straight fit and choice is wast.

also interesting is thermostat for lada models 2101...(all models in between).. 2107 which are interchangable with 131/132 lower radiator hose thermostat and is also available in "low temp" mode. in my lada is the one with 68-86 temp range, while "standard" one is 86-96. price is 12-15e range.

I read this topic with most interest. Here is my opinion as a mechanic and also as a 131 Abarth owner. For normal use the original set up is perfect. My Racing has the original stuff. But for racing you could consider a lower temperature thermostat. Because the engine runs higher revs it will produce more heat. Therefor it's better to have a thermostat that opens sooner. The thermo switch in the radiator should only be replaced when the engine reaches high temperatures fast.

In my Abarth i have 78 degrees thermostat and a switch on the dash for the fan. This means i have to check the gauge for reaching 80 degrees and turn it on manually. See picture of another group 4 dash.

that might be a hit or miss affair. i prefer a setup with fan switch doing it's job but with manual override switch.

there's also another solution which worked fine for me for years. i had a 132 diesel which was smashed before i bought it and original radiator was replaced with one from regata diesel. 132 was 2,5 liter and regata 1,9. radiator from regata was about 3 liters smaller capacity. in original 12 liter system. that makes a lot of diference. i was unable to find original radiator so i had to find another solution.
i used complete switch/thermostat setup from hausehold water heater. although it was made to work with 220v AC current it worked just fine with 12v DC, connected via relay. temperature probe was glued to the bottom of the radiator and i kept temperature adjustment switch also which was bolted under the hood. i also installed BIG fan from bmw 5 series. that system could be adjusted to kick in at range from 50'c to 100'c. i usually kept it at 80'c in the summer and 95 in the winter.
it is a strange solution but it worked fine and i kept it even when i was able to find original radiator after year 2000 when serbia finally got out of wars and sanctions...
