this thermo is installed with the spring down. as for a new radiator? thats just odd. i can imagine that that would be the problem. like i said it runs cool with no thermostat.

Take the thermostat into the kitchen an place it in a pan of water. Put a cooking thermometer in there with it and turn up the heat. Make note of the temperature where the thermostat opens. You may have run up on a dud.
