 half or 3/4- normal for this car for the last 50000 miles.

 Which can I believe, or is there a reason for the condition that might
 be known?  It has never done this before.

 Thanks in advance, >>

Keep in mind the following two things whilst diagnosing this problem.
1. The light is to indicate a low coolant level.  The coolant level sensor is
located in the cap of the plastic coolant tank at the left/rear of the engine
compartment. This is NOT the tank you can see through the license plate hole.

2. The circuit that activates this light "latches" the light on whenever the
coolant level drops - even for an instant.  To reset the light circuit you
must turn the van off & then back on again, otherwise the light will stay
activated "forever".

Good luck,
