Found my problem for my Hi and false temp gauge reading. I guess I should have known that the temp sensor on the block just below the Cylinder Head was feeding the Temp. Gauge not from the Expansion Tank . Pulled off the  connector at the sensor and the Gauge fell to zero. Replaced the sensor, and road tested ,rechecked with IR Gun all is well. Remember this is a inline Tiico. I am a Happy Camper again.
