<font face="Verdana, Arial" size="2">I remember a few years back reading that the heater should be run at least once a month to prevent the coolant in the heater core from going bad. I was reading a repair manual for a '90 Tbird and it mentioned that the engine coolant is always flowing through the heater core, and when you turn on the heat, a door opens exposing the heater core to the passenger compartment. I live in Hawaii and never have any need for the heater but should I be running it once a month, or is it a similar design to the Tbird?
Thanks.</font>
