What is the best way to bleed the cooling system? There is no bleed screw but the thermostat housing is vented to the expansion tank. My first thought is to let it self-bleed with the cap off.
the m5 is self bleeding. There is a small hose out of the expansion tank under neithe the cap. just make you you have enought coolant in the system with the correct mixture. one painless and great things our cars have.
