The car is running fine ( I drove about 300 miles with the light on). at highway speed at least, gauges seem normal. I have a feeling the cooling fans aren't kicking in. the relay is fine. The engine feels cool when it is running, turn it off, and come back 10 mins later and it feels hot! I have some basic tools, but no multimeter to read the codes. Any advice? Could the fans be ok, but the coolant temp sensor is shot? Oh yeah, its a 91 rt tt.
