Please help. 2001 bmw 325ci. Was heating up. Changed radiator that had a leak, overflow tank, thermostat and also replaced fan clutch. New hoses as well. When car is idling , is fine once I drive for 15 mins, temp goes up to red, sometimes comes down, sometimes stays red. Shut off for 10 mins. Then restart, Temp is back down but goes up once I drive. I think I bled system correctly, but nothing seems to work, any ideas ?
Make sure you do some reading on bleeding the air from the cooling system and bleed it again. Also did you change the water pump?
+1 on Water Pump, but If engine was overheated It could be a head problem. these I6 engines tend to go bad when overheated.
