What makes you think your heater core is bad? Air trapped in the cooling system can also prevent the heater from working. And until you are sure ALL air is removed from the cooling system, you don't know whether the ECT switch or ECT sending unit is bad.im just gonna wait it doesn't make sense to bleed it at this point. still have to change the sensor and heater core. i really dread helping out with the dash removal. but im learning a lot helping with this project. im pretty sure air in the lines wont make the gauge not respond at all. and the fan didnt come on ever. before or after changing the radiator..
You are wrong and don't know much about your cooling system.im pretty sure air in the lines wont make the gauge not respond at all. and the fan didnt come on ever. before or after changing the radiator..
