Wasnt sure whether to post this in engines or electrical so admins please feel free to move if needed.

I want to look at lowering the temp that the radiator fan cuts in at. It currently cuts in at the correct temp I believe after searching the forum but this does seem to be rather high and I dont want it to cook my head gasket. (Currently cuts in at about 97 degrees. Anyway I remember seeing on the Fiatforum when I had my cinquecento a guide on how to lower the threshold temp but I am not able to find it.

Has anybody on here made the same mod and can point me in the right direction of where to look. I have searched the forum but I have not been able to find anything.

Thanks guys.
