I've sent this info yesterday and today - but unwittingly used the ACRE
address instead of FlyRotary addr.  Sorry for any inconvience and for the
delay in getting this to the FlyRotary list. (I fixed my Address Book so I
will know to whom I am sending e-mails!)

Here's the info again - cut and pasted from original e-mail:

Re: recent problem with "no or little flow" of coolant

I stumbled on this link for an easy-to-install coolant flow sensor at
http://www.usradiator.com/diagnostic.htm

I cut & paste the info here:
"Digital Flow-Meter
   We now offer in our complete line of cooling diagnostic tools,
instruments designed to help professionals better understand cooling system
failures.  Our new Digital Flow-Meter quickly and accurately measures
coolant flow in gallons per minute at various RPM's while testing the
vehicle in a garage or on a read test (this unit is portable and can be used
while driving your vehicle).   Obvious mechanical failures such as worn
bushings and seals are easy to see and diagnose, but inadequate flow and
cavitation caused by worn impellers can only be revealed by accurately
measuring the cooling flow while the vehicle is running at idle or test
driven.  The battery operated Digital Flow-Meter is light weight and
portable with an easy reading lighted dial.  Unit comes complete with a
1-1/2" I.D. connection, wiring harness and easy calibration procedures.
Installation is simple, unit plumbs directly into top radiator hose with
wiring harness plug-in.  The length of wires on the harness will easily
reach from vehicles engine compartment to inside most vehicle cabs.
Batteries not included."

I think we've been looking for (wanting) this for a LONG TIME.
