yes, it's my understanding that the thermostat begins to open at the rated temp, say 180deg, and is fully open at say 200. So not only does it warm up the engine quickly, but works to maintain a certain temp range. Assuming you're not over 200deg, the thermostat should be less than wide open and dictating the temp... at least at the point of the thermostat.
I have had people tell me that the thermostat is either open or closed though, which may be the case, but I don't think it matters. Even if it is a hard switch like that, once you hit 180, it would open, coolant would flow, temp would drop, 'stat would close. Open, close, repeat, to maintain 180deg or something close to it. As long as the system had the capacity to maintain 180 (and it should), it would. Being a mechanical device, and understanding somewhat how it works, I'm betting it wavers slightly in a partialy open condition to maintain the temp. If I get a chance, I'll verify tonight with one of the extra 'stats I have. From what I remember in testing them previously, they don't just open or close, they are capable of partial states.
I understand what Water Wetter is SUPPOSED to do and why, but why that would change the temp gauge readings is what confuses me.
