I got nothing to add to the cool weather question. All I can say is that
on one trip up to Palomar Mountain last year, the coolant light on my 84
started to flash. I pulled over, looked at the tanks, couldn't find
anything wrong, crossed fingers and continued the climb. The lamp
continued to flash incessantly for a few months afterward, then quite
mysteriously stopped. Now it just flashed when I want it to: when the
engine is first started.

If anyone wants to write a nice article about this wondrous and sometimes
puzzling circuit, PLEASE do so at http://vanagonwiki.net/index.php/Coolant

If you haven't already, all you need to do is Create Account (upper right)
and you can start an article. No real writing skills required, just have
at it! If it's a mess, ask me for help! I don't claim to know anything
about how these things work, but I can clean up the page. We can all add
troubleshooting tips for the next guy that is staring at a blinking
coolant light.
