I had the same problem with my TR3B. I though it always ran hot or was
getting ready to overheating. Not the case. The car after warming up
would always read at 3/4's on the guage not at 1/2 or normal temp.(I'm
not sure what the guage says)After checking the thermostat and
radiator cap I got a "candymakers" thermometer from the local hardware
store (they are getting harder to find all the time!) and let the car
warm up. I let it cool down enoough so that i could take the radiator
cap off and making sure there was a filled radiator put the
thermometer in the radiator and let the car run at idle while checking
the thermometer. Sure enough the thermometer read about 15-20 lower
than the guage and the car never has overheated even in the worst heat
of the summer.
