I have had a few responses to this issue so far.

I never had this problem until a week ago.  The weather has been warm, unseasonably warm here in the SF Bay Area.

My tendency is not to be too alarmed, but something has definitely changed, and it hasn't been the weather.  My thought about the long block change that made all this go away for John Lauterbach, is that there was another part he changed that actually fixed the problem, not the whole engine?

So we all start our boxers and the light blinks for 5 seconds or so before it goes out.  Why?  Is the sensor a flow meter, so when the water gets circulating, that the light goes out?

Or is that just a delay time for the computer to do all its checks on all the systems including the temp sensors?

Perhaps I have a cooling system that needs bleeding, or has let in an air bubble, or maybe I have a flow issue related to an old radiator?

Anyone know?  I'm searching the archives.
