Mike,
If you monitor the temp of the expansion tank using a temporary
thermocouple taped to the tank and a digital hand held thermometer, you
can record the differential temp between the CHT and exit coolant temp.
Then you put another max line on your CHT gauge for coolant and the job
is done. My exit coolant temp works out at 25 degs C less than the CHT
pretty well throughout the range. I understand that doing it this way
is an acceptable compliance with the SB and saves another instrument in
the panel (unless, of course, you have an all singing all dancing EIS)
and more plumbing and wiring etc. If you wish to monitor coolant temp
directly all the time, Skydrive sell an insert tube with a sensor for
one of the coolant return pipes to the expansion tank, plus gauge etc.
Hope that helps.
Best wishes,
William

Has anyone come across a modification scheme to introduce a water
temperature sensor into the 914 engine installation.
