It seems like I have had to burp my radiator 3 times already. Each time after a drive the upper hose is rock hard and it takes a little more coolant. I have probably done hundreds of timing belts and tstats and never had this much trouble burping a system. I ran the heater, elevated the front, and opened the bleeder. I even filled the radiator super slow. My temps can get as high as 206 and my upper hose is rock hard. Are these cars a little tricky or do I have a problem? I am an ex Toyota tech and I am somewhat new to my twin turbo
