Is the Safestat thermostat a Motorad Failsafe thermostat?
http://www.motoradusa.com/fail-safe-thermostat/"When overheating occurs, fail-safe automatically locks in the open position to permit maximum coolant flow" Some people report that once it overheats it stays locked-open?
If it is not that thermostat, does the Safestat company have a website?
