so we are talking about a Thermostat for air-cooled Type IV VW engines.. ok...nice to know. all right.. starting all over .. sounds like they are working to me.. just late in opening .. for winter.. you sure want it warm.. ( and there might be cable length adjustment ..??.. I try to stay far away from anything vw and air-cooled these days ) if for get the temps you said ..100C is 212F of course.. doesn't seem like the t-stat should try to keep the engine that hot. so maybe they are both faulty. I'd think it would aim for something like 160F ... just a guess. The vast majority of people on this list that have and drive gasoline vanagons have waterboxer engines .. so when you just say 'thermostat' .. that is where their mind will go.........to a liquid cooling type t-stat for vanagons,.
