OK
now I'm in a bizarre cyclical thing with the coolant temp
several days it'll run nicely cool, just below the LED
then it'll start creeping up - left light, mid light
for a while it ran at the right edge of the LED
on instinct I did nothing about it except make sure everything was topped up
sure enough several days later started running cooler
then about a week in the normal place again
then back on up...
I don't think there's air in there
seems more like a clot of some kind, a sporadic restriction of coolant flow
I have an image of this plug of oil moving slowly through one of the cooling
tubes like and aneyurism and when it reaches the engine my van is going to
explode, antifreeze, sheetmetal everywhere, the tiny little black expansion
cap soaring, soaring heavenward
or maybe this thing is following the phases of the moon
it's about on that timeframe, this up and down thing
maybe I should check the almanac
any other suggestions?
