I was fiddling with my car today because I was tired of not doing anything about it after it overheated about a month back. She ended up taking about a half gallon of coolant between the degas bottle and the crossover and I still wasn't done. I heat cycled it a couple times during the burp process and by the end it was still taking small amounts of AF but not like at first when it gulped it. My question is this: how do you get the cluster to read in diagnostic mode to see true coolant temp? I read you depress the odometer knob with the car in key on, engine off but all I kept getting was the trip meter.
