This is the fan thermo switch ERA uses. It's a 75 Centigrade switch:

Switch, fan thermo -- 1980-1984 VW Rabbit, Jetta: 823 959 481/75

Why would VW even make a fan switch that ran the fan all the time? If you wanted it to run all the time you wouldn't need a switch. If your lower radiator hose can't get below 167 degrees Fahrenheit then something is not right.
