hi doug,

i agree with you re the swing of the gauge. most of the time the gauge was dead center but it did change. what you describe sounds normal to me but once you get a sense of the 'normal' for your system, it's always worth watching for further changes. i think my fan cycled more as the miles built up and now i'm trying to get a sense of the new engine's and cooling system's qualities. if i can believe my gauge, i think it's now running a bit too cool overall since the gauge swings between 1/3 to almost 1/2. i may actually put the old thermostat back in.

if i read woodie right, his gauge never swings at all. this makes me wonder if his fan ever comes on? if it does, then at what temperature? he seems to be suggesting that the temperature difference between 'normal' and the temp at which the fan comes on is so small that his gauge doesn't detect it. my gauge always seemed quite sensitive ....... and system and environmental differences made slight changes in the range and duration of the gauge swings. i think the integrated multiple sensors and computer compensations are quite sophisticated and it may be that woodie's systems are accurate and functioning optimally and they keep the temp in a very narrow range. that certainly seems desirable.
