Dear friends... I am new to the forum. I would like to ask your opinion on a R53 overheating problem. Turns out coolant boils out of the expansion tank, fans don't turn on when the temperature gage gets to halfway. I have follow the procedure for a safe bleed and coolant refill. So far I have replaced temperature sensor, radiator and thermostat because I found they were bad. Expansion tank is for delivery in a couple of weeks but I don't think it is bad, it just looks old. The car was probably overheated like a week ago. Is it a good chance that may have blown the overhead gasket? Any ideas? Any help is very appreciated...
