Tonight, we had a very strange thing happen... We had been driving all day in
100+ temperature and the van ran fine. Tonight as it cooled to a balmy 95, the
coolant light kicked on while at a stop light agter a short drive. We do not
see any leaks-thank God-but, as we pulled into the driveway we could hear the
coolant boiling.  Any ideas? Thanks, Christine and Dan and Althea 91
