Does anyone know hot to bleed the coolant on a 2001 4.4 X5? The truck is running fine but the coolant level light comes on everytime I shut it off. I just replaced the waterpump and hoses and tried to bleed it by doing the following:

Car off
Loosen bleeder screw
Turn car to position just before starting
Turn temp to highest setting - fan to lowest

There are no bubles coming out and the fluid is full

Thanks
