SO I worked on burping the system - spent 30 minutes idling after it was warmed up - heater on high etc.. nothing changed - the fluid in the reservoir never changed position at all - from cold to hot it stayed the same. The fans ran - which was good - but the temp still climbed up pretty far. The heater wasn't blowing warm air either - it worked fine the other day when I was nursing it home (had the heat on hoping that would help keep it cooler.) Any thoughts - does this sound like a thermostat issue or temp sensor?
Thanks
