I don't know how accurate my gauge is. I run no thermostat in my 100 Six and
have the sleave installed to run that way. Temp sensor in head.
Temp stays under 180 most San Diego days (70-80 degrees lately). usually is
about 160-170. It doesn't act like it's any hotter. No excess coolant spilling
out. Seems just fine.

Coasting down a hill, it often gets below 160. Driving along steady on a mild
day it will stay at 180 (expected), then exceed that on a hot day pulling a
load or sitting in traffic. My heater is usually off--but the valve on the
block is open year-round--and I've used it as an 'auxiliary radiator' when it
gets close to 212deg.

The only explanation I can think of is that the engine is sufficiently
air-cooled in benign conditions to keep the thermostat closed. I've tried
several thermostats with same result, and have tested a couple on the stove in
hot water. Apparently, others are experiencing the same phenomenon.
