Evening all I own a 96 sti . Over the last few days despite the temp gauge showing normal temperature (around halfway), the heater is blowing cold air' And no matter how far I drive the radiator is always ice cold. Have had these symptoms before in previous cars and after taking the thermostat out things have been fine. Is this the thermostat? or a deeper problem? thanks for any advice
