Just changed both sensors on my Bro's ST2
Good info here:

https://www.simpsonsupplies.co.uk/EN...FIAT_2895.html All that needs doing is the crush washer filing down ever so slightly and it fitted a treat without any modifications.....
cost: £8.71
Only a few pints of coolant came out, remove upper right dash cover and access coolant top-up bottle (and if necessary - radiator cap) and it could probably with a coolant refresh in any case - or, filter and reuse the old.
Good luck - Frank
