Jim:
I have been running a temperature gauge to both locations and have seen a 15
degree difference between then on occasions. This may be the result of
running a Plus 8 radiator in my Plus 4. During the winter the radiator
location will barely move the needle off the stick (130) but does show
spikes when the thermostat opens, meanwhile the thermostat housing shows
170 . .
I agree with yours and Freds statement there SHOULD be little or no
difference between the installed thermostat temperature rating and the gauge
reading, given the ideal cooling system, however Morgan does not have the
ideal cooling system with it'd fan some four inches behind a radiator
limited in size by the body design and drawing air from an uncowled opening
,. Morgans will show a fluctuation in temperature.
With todays 107 (F) temperature Duchess did tend to run a few degrees
hotter in traffic than the the 170 (F) thermostat and once moving did come
back down to a respectable 185 (F) .
My point was simply that a Morgan which runs 200 to 205 in traffic and 185
on the expressway is not necessarily something to worry about.
