I had a similar problem with my Riley One-Point-Five. I took a meat thermometer
and put it in the radiator. I started the car and let it warm up. I could
compare
the guage with the actual temp. The guage was correct. I took the new thermostat
and put it in a pan of water. I monitored the temp and watch to my amazement the
thermostat didnt open fully. New didn't imply it works in my case.
